At last someone who gives clear detailed instructions on how to use a PSU. Ive watched loads of videos but your is by far the best for a total female beginner. THANKYOU
For the last few hours, I've been trying to bring myself up to speed on using my entry level benchtop power supply. Your video is the clearest and straight forward so far. Thank you very much.
Thank you so much for this video!! I just bought a cheap power supply and i was just getting ready to send it back because i didn't think it was working. You explained everything so well!! I have been watching videos for the past hour and they all had me confused. Your video got me back on track. Thx again!! Take care!! Aaron
I knew I could set them but I never really knew how they worked in concert with eachother, also that’s crazy bro you just found that out with all that you do @sreetips lol :)
i bought a power supply because i plan on doing some electroplating, and this is the best ive seen so far I know this video is 2 years old and you've probably since moved on or perhaps have already done so but a best practices and safety video would be nice for those of us who are a bit gunshy
Thank you so much; I have a power supply and this was no where in the whole instructions and it is made by a diff manufacturer… and this works thanks thank u
I found your video via Perplexity 8-) which is cool to have a human explaining. Thanks for showing the setting of ceilings values, and charging that li-on battery which I was trying to do to revive a death dewalt 20V pack.
Thanks man! I got myself a power supply about a year ago similiar to the one on the right except mine's Evetek and it doesn't show wattage, but to this day I had been rocking my brain in figuring out how to display the change in current output on the machine, so I gave up on it supplying current and just focused on voltage. Appreciate the help!
I started researching how to use these because I thought the one I bought was broken! At 3:00 you answered my question! Don’t forget the rubber gloves! 🤣
Nice video. A couple of features to look for that don't necessarily add a lot to the price are a lock button that locks your adjustments so you can't accidentally change your settings and a separate power switch to allow you power on/off to the leads after you've adjusted your settings without turning off the main power.
Thanks for the video. I just recently purchased the Longwei that you have. I was mostly conserned that I might damage it by miss using it. Thanks again for a clear explanation on the proper use.
Thanks for sharing your experience and thoughts. I am currently researching bench top power supplies. Appreciate you explaining these details and differences. Helpful video Update: Just ordered a Longwei 3010D with course & fine adjustments from Amazon 2 day delivery 😎😄
I have a unit similar to the one on the right. "Nice" is the brand on it. One of the many sellers warns you to ONLY adjust the current limit (by shorting the leads) when the voltage is set to 5 volts or less! That isn't mentioned anywhere in the manual that came with the unit.
Very nice tutorial. I have been using the Longwei identical to the one you were demonstrating for some time, but this video actually taught me some things I did not know about the unit. Thank you.
I know it's an old video, but it helped me get my head around how to use this. I'm using kind of the same purpose as you with lithium cells. Mine have dropped to 0v so bumping them. See if they are any use so putting them to 3.6v and testing the resistance. I'm not very good with electronics so doing this in the garage. I have built 10s4p packs and 12s3p for my electric skateboard but with new cells. I managed to get hold of couple hundred or so recycled cells see if i ca do something with them. Thanks for the quick video
Thanks for this. I just bought the Kungber 30V 10A unit which I like. This said the instructions that come with the unit are okay, but only okay. I really needed to see someone step through the basic possible configurations of the device, with constant current and constant voltage, and the automatic cross over between the two, in order to understand how the controls work and what the displays mean. The Kungber seems like a well made, basic tool. The wattage display is a nice bonus.
Well explain to me how to use it. I recently bought the same exact model, and I really only need it to test headlight assemblies. I'm confused on to set the voltage, and amperage. Most of the assemblies I'll be testing only need 12v, about 4 amps, 55w at the highest for bulbs. So do I set it at like 13 volts, 4-5 amps, and then it's plug and play to the assembly?
The current control is just a current limiter, that is all it does. You can leave it on maximum for most things. Its useful if you are testing something that is delicate, ie a new circuit you are testing and you want to limit the power for the trial run to make sure nothing overheats gets damaged.
It has been quite a few decades since I diddled with electronics, at least in "bench mode." I've just gotten this new Kungber and am still trying to muster the courage to actually connect it to my breadboard circuit. It is just ~so~ counter-intuitive to me to see my selected voltage in the display and SHORT THE OUTPUT! But I'm doing it...ever so gingerly. I think I am going to pretend for a while that the current controls just do not exist (like in my old-timer experience). I really do not like to work with power without feeling absolutely in control, without everything being completely intuitive. OK, I'll set the current, but only change it with great deliberation. I guess I feel like I have to, because I don't see the easily accessible fuse on the front panel, which used to put the brakes on my current. And, of course, I can see that this is really so much better, because a one-amp fuse my have limited the fire hazard in the past but didn't do much for protecting the low-power ICs and other components that we mostly work with now. (If I had been on the design team for this product, I would have insisted on a button that said "Adjust Current" and shorted the output internally without me doing such a wretched thing myself. IMO, kinda bad to initiate total newbies into any kind of electrical work without supporting their wise instinct not to connect + straight to -.)
New subscriber trying to learn as much as I can before my Lithium iron cells arrive. You explained this perfectly not everyone watching understands what each piece of hardware being used is for.
Your black psu do turn off instantly, but it takes a while to discharge the output capacitors. If you connect a load and turn it off you will see that it shuts down almost instantly...
i have one that has a special knob instead of a potentiometer style thing, and when you press on it, you can change which digit you want to change, so it works as a coarse and a fine knob at the same time.
This is the video i needed! I am currently trying to charge a 12 v motorcycle battery. I am limiting the volts at 12v and the amps at the max battery amp input at 2.6 amps. I am curious why when I connect the power supply to the battery it only draws 0.008 amps.
It maintains cv and will not switch over to cc to supply the battery with a decent amount of current to charge it quickly. Its a lead acid battery so i’m not eager to test my hypotheses on it. If i bump the voltage ceiling up i do notice it will take an appropriate amount of current but i don’t want to explode a battery in my garage.
12V lead acid batteries typically charge at 14.4 volts (that's what a cat alternator generates). Check the datasheet for your battery's recommended charge voltage.
Great info. The manual was more than lacking information. Especially on set up. Is there a way to set s fixed output for both Voltage and Current? Let's say I want to supply a constant 36V at 8A, could this be achieved?
Great video thanks for sharing, it’s possible the kungber has residual charge in it capacitor/s and takes time to power down, be interesting to switch it off under load and see if it powers down faster. Thanks again for a very informative upload.👍🏽
If you want precise outputs of voltage & current use the power supply in tandem with digital multimeters & adjust voltage & current to your requirements. You can buy two DMM for $50 & now you have better metering for you bench power supply.
Note and an assumption on my end. As far as the black one staying on longer and the white shutting off instantly my guess would be that they both are shutting off slowly the white just cuts off the display. Would both have caps they need to drain?
Why one takes longer to turn off is it probably has a large capacitor in the circuit to have a move stable control. I'll have the one that takes longer to shut down.
Great video. The earth terminal. Are both power supplies isolated from earth . If you wish to get a positive and negative voltage can you connect the positive of one supply with the negative of the other
I'm trying to use one of these to electroplate. I set it to 3.0V, then short the terminals and set it to 0.70A. But then when I connect the object to the -ve and the zinc anodes to the +ve, it goes into constant current mode and only shows 0.3V & 0.7A. I can't adjust the voltage. I'm so confused.
That Kungber has two models, 5A and 10A. I wonder if the 5A can be modified to output 10A also. I bet they have internally the same components (for production efficiency by the manufacturer). It could be just one resistor affecting the max current limit.
I have a Kungber power supply like yours and I have been using it to drive a small 12V stepper motor. Today, I went to go use it and it is showing nothing but zeros. Zero voltage. Zero current. Turning the knobs changes nothing. Any ideas on how to fix this? Is my power supply junk?
At last someone who gives clear detailed instructions on how to use a PSU. Ive watched loads of videos but your is by far the best for a total female beginner. THANKYOU
and a male apparently. Thank you!!
Thank you for not having a 12 minute intro.
For the last few hours, I've been trying to bring myself up to speed on using my entry level benchtop power supply. Your video is the clearest and straight forward so far. Thank you very much.
Glad this helped. I went through the same experience.
Agree.😎
Definitely the best one I've seen so far
Mine has been sitting in the box until finding this video... It's like getting a birthday present all over again!
@@TheWilltoBuild if I set mine on 14V and connect it to a battery it automatically jumps into CC 🤦🏻♂️ HOW does it stay in CV?
The Kungber on the right is the exact model I just bought! The instruction manual looks like Google translate was drunk, so I appreciate the info.
Thank you so much for this video!! I just bought a cheap power supply and i was just getting ready to send it back because i didn't think it was working. You explained everything so well!! I have been watching videos for the past hour and they all had me confused. Your video got me back on track. Thx again!! Take care!!
Aaron
I saw videos regarding this power supply. I must say that this is one the BEST video and awesome explanation. Thanks a lot. 💐
Finally! An explanation on CC/CV power supplies that I can understand. Thanks
Glad it was helpful.
Finally ! A clear explanation on how to use these things properly and safely .... thanks brother ! 😊
Very helpful video! This is really what people will need if it's the first time they bought themselves a bench power supply
Excellent, I never knew that I could set my power supply like this until I watched your video - thank you!
I knew I could set them but I never really knew how they worked in concert with eachother, also that’s crazy bro you just found that out with all that you do @sreetips lol :)
Very good tutorial! I cracked up when you perfectly placed the ad segue when the camera mount moved. I like your videos!
Great video man, it took me 5 or 6 trys with other clips but as soon as u spoke I knew exactly how smart u are and how articulate.😊
i bought a power supply because i plan on doing some electroplating, and this is the best ive seen so far
I know this video is 2 years old and you've probably since moved on or perhaps have already done so but a best practices and safety video would be nice for those of us who are a bit gunshy
Thank you for a great explanation on setting the power supply up to read voltage and current.
Super helpful video for me to learn how to use a bench power Supply that is new to me.
Very helpful, as a beginner I appreciate this very much.
Thank you so much; I have a power supply and this was no where in the whole instructions and it is made by a diff manufacturer… and this works thanks thank u

Thank you. I learned something today. Now I can use my power supply correctly.
This is what I spent all day looking for. Thank you and nice job
I started researching how to use these because I thought the one I bought was broken! At 3:00 you answered my question! Don’t forget the rubber gloves! 🤣
loved this video, perfect explanation. not too much fluff and an easy way to understand. Thanks man!
I had challenge setting the current, thanks for the current adjusting explaination
Nice video. A couple of features to look for that don't necessarily add a lot to the price are a lock button that locks your adjustments so you can't accidentally change your settings and a separate power switch to allow you power on/off to the leads after you've adjusted your settings without turning off the main power.
Thanks, you have a easy way of explaining things and this helped me understand how to set the CC mode.
Thank you for clearing this up for me. It was a complete mistory until I watched your video.
Thanks for the video. I just recently purchased the Longwei that you have. I was mostly conserned that I might damage it by miss using it. Thanks again for a clear explanation on the proper use.
Great explanation! I just bought a similar unit but 32V/6A that have the useful output on/off button.
You definitely explained how to set up the Kunberg better than the instructions did. Wish I had watched your video first.
This is so helpfull dude.. i set mine to CV.. set my settings, connect it to my battery and it would go to CC.
But thats normal.. lol.
Thanks bro!
Thank you so much. Now i understand it alot better. And how you explain it is 100% spot on.
I'm with sreetips on this one man. Great job. thank you.
Amazing, thank you. As someone that knows nothing about this, this made it very easy to understand.
Thank you so much for the concise and bs free explanation!
10/10 recovery on the camera drop.
Thanks, great explanation of the constant voltage/current issue as well.
Just bought one to charge my headway lithium bank for my car audio system and this is a great explanation! 👏👏👏
Thanks for sharing your experience and thoughts. I am currently researching bench top power supplies. Appreciate you explaining these details and differences. Helpful video
Update: Just ordered a Longwei 3010D with course & fine adjustments from Amazon 2 day delivery 😎😄

likely to reduce arcing at higher voltages. 60V may produce a pop?
Helpful immensely. I also read your safety message in comments too that is excellent too. Cheers hey!
Thanks for making this video. Very helpful.
Very nice tutorial. I have been using the Longwei identical to the one you were demonstrating for some time, but this video actually taught me some things I did not know about the unit. Thank you.
Well said very clear and easy to understand. Thank you.
I like the ad break right when you drop your camera. Very suspenseful.
I know it's an old video, but it helped me get my head around how to use this. I'm using kind of the same purpose as you with lithium cells. Mine have dropped to 0v so bumping them.

Your video is very helpful and easily understood. Thank you.
Great video This is exactly what I needed.
Very concise and helpful for a total noob, thank you!
Thanks very much for this. Very helpful. Never new this at all! 👍
Very well explained for this newby 👍
Best instructions video of all
Thank you for video, my bench psu didn’t have detailed manual, this helped
Good explanation for beginners like me
Great video for me to learn. Thanks !!

plus, mine shows the max amps if you touch the amps knob for about 5 seconds, which is very useful.
Your audio quality is very good
Yes that was very helpful. Thanks I appreciate the advice
Very good tutorial, exactly what i was looking for.

Very good video my man. Best one out there!
9:50 not only destroy it but if you're not there you can set your house on fire with these
Great video thanks for sharing, it’s possible the kungber has residual charge in it capacitor/s and takes time to power down, be interesting to switch it off under load and see if it powers down faster. Thanks again for a very informative upload.👍🏽
That's a very good point - I'll give it a try.
Thank you very much for a nice video👍
That was incredibley helpful, thank you
Great video. Answered all my questions.👍🏼👍🏼
If you want precise outputs of voltage & current use the power supply in tandem with digital multimeters & adjust voltage & current to your requirements. You can buy two DMM for $50 & now you have better metering for you bench power supply.
When would you use the ground plug connector?
Note and an assumption on my end. As far as the black one staying on longer and the white shutting off instantly my guess would be that they both are shutting off slowly the white just cuts off the display. Would both have caps they need to drain?
Why one takes longer to turn off is it probably has a large capacitor in the circuit to have a move stable control. I'll have the one that takes longer to shut down.

Great video, great explanation
Thanks for this
Great video mate , well explained 👍🇬🇧
Great video. The earth terminal. Are both power supplies isolated from earth . If you wish to get a positive and negative voltage can you connect the positive of one supply with the negative of the other
Well explained! Thank you.
Is there a version of these types of power supply that keeps track of how much capacity they charge over time?
Thanks for the video, awesome!
Could I use this to charge a gen 2 prius module instead of a hobby charger?
I'm trying to use one of these to electroplate. I set it to 3.0V, then short the terminals and set it to 0.70A.
But then when I connect the object to the -ve and the zinc anodes to the +ve, it goes into constant current mode and only shows 0.3V & 0.7A. I can't adjust the voltage.
I'm so confused.

Wish I would have watched this about adjusting amperage... fried an Arduino board lol. I was like why isnt the amps moving....
Hi, I have a nicd battery pack with 8 X 1.2v 800mah batteries, what would I set my voltage and amperage to for charging it?
What are the settings to connect a car battery for a garage car stereo system?? Thank you
I have a sps w605 I set the cv to 18 for a 18v battery and the amps at 5 put the battery on it and it shows the cv but no Amps is that normal
I have a Kungber power supply like yours and I have been using it to drive a small 12V stepper motor. Today, I went to go use it and it is showing nothing but zeros. Zero voltage. Zero current. Turning the knobs changes nothing. Any ideas on how to fix this? Is my power supply junk?
how can I determine the max amperage for a component? like a car fuel gauge or something of that sort.
can this supply be used to.isolate a short or does it got short protection
In order to adjust the current you have to short the leads. So I imagine you could use it to isolate a short.
Great video thanks !
