Had to get one of these as I'm regularly charging high voltage batteries, and this will allow me to set custom voltages on my batteries depending on needs. Just put it together yesterday. I didn't even bother testing the 70v supply- I just put everything together, plugged it in and it worked. I can't imagine what a similar specced unit from western manufacturer would cost.

Nice unit specially for the low price. I got one of these, managed to get it in february before the Corona lockdown. Got the control unit and the case. Buildt the powersupply out of an old transformer, and it's working great. You can program and store different voltage and current settings. The battery holds the memory for these presets.
Very neat little power supply, I can see this being very useful for people who need something that cost effective, I kinda want one. You did an excellent job explaining how it works too 👍👍
Nice review. Would have been nice to also see: - if it could deliver 60V/12A safely without overheating or burning up - if it would regulate battery charging when the temp sensor was reporting high temp.
I have a smaller unit. The DP30V5A. Mine has been a good unit for the last 2 years. Only problem I had was, the main schottky diode burnt up, just 5 days after I had it. I botched a through hole schottky diode on to it & never had another problem. I think they make good products, it's just that the surface mount Shockey diodes are weak. If they happen to burn up, just replace them!
Hello, you may type the desired voltage and current. Just press volts button, type let’s say “13.8” and hit enter. There is a case kit with fan, fuse, temperature for switching power supply and as an optional the switching power supply itself for this converter.
Built mine some months ago, using an industrial grade power supply (350W 60V for stepper motors/CNC) that fit into the enclosure (you also should have bought!). Works fine and is still much cheaper than any other from a "known brand".
hello, I see that in your video description, it is Banggood link, they are not going to sell the RD series power supplies any more after clear their warehouse stock,if you like, you can use our RD aliexpress official store
@@12voltvids Amps are not power. Such a switching converter has an efficiency of typically 85%. At 30V and 10A, for example, this already results in 45W heat. This is too much for the small heat sink...
I would like to see you build your power supply for this. The one I made for myself. goes to 30 volts. 5 amp. I'm using a power supply from a power chair. It has a toroidal Transformer with a full Bridge rectifier board & a 2000 uf 63 V. Capacitor on it. The power supply says it's 24 V. RMS. 3.33 amps. By DEWERT . , I thought it was perfect for the DP30V5A. I ended up burning up the surface mount Shockey diode in it. I replaced it with a through hole schottky diode, botched it. It's been working great ever since. I learned how to make it from watching you on your Channel. Thank you & keep up the good work!👍
Thats one smart unit, i can see it being very handy :-D You can never have enough power supplys or meters. My only requirement is to turn down or change the pitch of the beeper, it would send me mad sorry madder :-D
@@rdtech9153 I saw another video where the RD6006 had a substantial ripple on the output. I was wondering if that had been resolved in the 6012 as I just purchased one of these units a few days ago.
Why do you keep switching the load on and off to adjust Voltage and Current? The whole idea is to make those adjustments with the load switched on, so you can monitor the parameters WHILE you make the adjustment.
I was showing the current limit trip. Just trying to find the trip point for cold filament. Remember incandescent light bulb draws much more current when the tungsten is cold. I wasn't turning it off. When I had current max limit set too low it tripped and turned off. I hit the button again to turn on again before the filament totally cooled down allowing it to stay on. It was more of playing with it to see how sensitive it was. Since the current limit is a hard switch off not current regulation as the other setting is, it shuts down. Now the current regulation could be used to limit in rush current, set that to the max that the lamp needs to operate and it will limit the current to that level as opposed to the OCP or OVP which shuts down if it exceeds setting.
@@12voltvids - I was referring to adjustments at *other* times. For example at 10:29 to 10;42 when you adjusted from 13.8v to 12v then upon switching on again showed that the HID headlamp was "Constant Power". So my point was that the Current and Voltage limits can be made dynamically, which is a great way to learn the characteristics of the connected device. For example, by slowly adjusting the voltage up and down, you can determine the dropout voltage of the HID ballast, rather than making multiple adjustments with a power cycle in between like you did from 9:38 onward.
will be an interesting project indeed..im looking forward to that one not only as a bench top dc power supply but wondering how it would work in a solar setup im thinking of installing .. using the charger feature and the solar panel as the supply and lead acid batteries as the storage medium on cloudy days..
Since this is a "Buck" regulator, it can only supply up to a couple of volts lower than you input voltage. So if your solar batteries are 12V, the PSU output will be maximum about 10V. This is not the best unit to act as a charger, you should use a proper MPPT controller for charging the batteries.
Hmm, it can take up 70V DC, I have a few big transformers from old AV receivers. I wonder if they have one with symmetric +/- power supply - it would make nice Lab PS.
@@12voltvids ok. I never heard of ANY being 4.3. I've been buying them & using them in different projects for the last 6 years & using many different types of 18650s. My interest in them started when I gave up smoking & started vaping. ALL of my vaping products use 18650'S. I probably have over 100 of the batteries laying around & just recycled About 100.

@@ronniepirtlejr2606 How many of those green ones I showed in the video would you like to see. I have 4 of them right here now, and they are all fully charged, 4.31 volts.
Could somebody explain to me why it has the green output jack for charging purpose? The red output jack should be good for charging. What other functions that the green output jack can have for charging?
You supply the input power using a suitable PSU or transformer. Better to use a transformer plus rectifier and smoothing caps, since the Switch Mode power supplies have a lot of nose which gets superimposed onto the output of this controller. You can use any input voltage that you like, up to a MAX of 60-70V. If you use 12V supply, you get about 10V out, whist using 24V will allow you to output up to about 20V.
Nice. Double check all settings if charging Li-ion batteries. I'd put 'em in a metal box (.50 cal ammo can from Harbor Freight?) capable of containing a battery fire (especially if left charging unattended). Very thorough demo. Thank you.
Li-po for sure. The standard 16550 types are pretty safe. They have internal fusing that kills them before they go up. That is what the temperature sensor is for. To shut down charging before they get to the explosive stage.

Here is one of those moments to educate. A standard layout is 789 456 123 0. Every computer keyboard and calculator is laid out that way as are all scientific instruments. You are looking at a telephone keypad which is 123 456 789 *0#. Do you know why the telephone keypad is laid out that way? I all has to do with the way that push button phones evolved. They started (when automatic dialing was invented) as rotary dial phones. If you look at the keyboard you will also see letters. Starting with 2, there is ABC, 3 has DEF, 4 GHI, 5 JKL, 6 MNO, 7PRS, 8 TUV, 9 WXY. Note that I omitted Q and Z. There is a reason for this, and all the telephone workers that have been around a whle will know what I am talking about. In the early days of telephone dialing, each distric in a city had it's own central office. In Vancouver, ,where I am from we had central offices with names, and to this day the names have not changed. ALpine, FAirfax, MUtual, CAstle,TRinity ect. The Nxx (first 3 digits) of a 7 digit phone number was hard coded to the exchange. In the early days there was 5 digit dialing as well, I will go into that. (in some cases 4 digit) Each block of numbers went from 0000 to 9999. That means only 1000 possible phone numbers per block. So in the central office there was a pre selector, that went from 0 to 9. Now you have 10,000 possible numbers per central office. Each central office had a 2 digit office code, which were initially represented by the office name. Your phone nuber could be ALpine 5 9907 for example, or MUtual 8 2554.. To dial this number, you dialed the first 2 letters for the office followed by the switch number and then the line. ALpine is 25 then the next digit was the switch code 6, followed by the house number 9907. In the earlier days, when there were fewer than 1000 numbers in the office, you would just dial the office followed by the house code. (Those numbers BTW were real, the first was my wife's parents number when they first got a phone. I have that old ancient rotary dial phone here and it still works, and has the original number card with AL5-9907 printed in it from BC Tel) The second number was the old request line for 73 CKLG radio. Anyway, back to the keypad layout. Since the phone system had used letters going way back to the early days, to this day the letters are on the keypad. We use them now for things like name dialing, hence they added the Q and Z. To keep things simple, the numbers were arranged 1 2(abc) 3(def) ect on the phone keypad start at the top row.
