OOPS I spoke tooooo soon in my last comment , Later in the video I saw you adjusting the volts and saw that it is the click type for the different adjustments , I rather that over the coarse and fine knobs.......
I ordered one from Ali Express when I found out that stepping was controlled by pushing the Volt and Amp knobs in , and I paid 64.00 USD plus sales tax and a lil shipping came to almost 77.00 dollars .... I sure do like mine and it can charge a large tablet fully in a short while ....I also like that Ice white blue color on the display...
The stepping is very handy, lets me control at different granularities. I was able to test a board at different voltages and see it's current consumption, with a current limit in case the board-under-test misbehaved.
If you attach a device that needs a lot of current, it would generate more current, up to a limit. There may be a constant current mode, but if the device has a large enough resistance then it may not be able to adjust voltage enough to make that current. It has a voltage limit of 30v.
Thanks for the video :) Any chance you could do a follow-up for the PSU using you oscilloscope to check for output ripple voltage, transient spikes and peaks, over voltage etc. on the PSU eg. when powered on, switching output or adjusting voltage?
@@JohnColemanesque same. ended up buying DPS series and its on/off as well. i very dislike that but seems like it would be the same if i went for the other series so i will prob keep it
@@corinasechelariu1307 actually I missed that part where he turned off the beep and found out that the push select of the knobs changed the numbers , I actually saw that in another review video, I ordered one from Ali Express and I paid 64.00 USD plus sales tax and a lil shipping came to almost 77.00 dollars .... I sure do like mine and it can charge a large tablet fully in a short while ....I also like that Ice white blue color on the display...
Can the beeping sound be made less loud, or is there only an option to switch between on and off? In fact I was thinking of soldering a little adjustable potentiometer in-between the beeper and one of its wires, maybe someone could advise me on what value would probably be suitable?
Hmm, I'd have to check the manual to see how the controls worked. I'll admit, that after unboxing it, I nearly only use it for different voltage outputs and monitoring current while doing it - although i use it for that a lot. As for adding the extra resistor, possible, but take huge care before rummaging in a power supply, there will be capacitors with nasty shocks in them, and stay well clear of the mains side.
Does it show you real time current being drawn if you adjust the voltage? Reason why I’m asking I seen another video and it does show it but after a few seconds
Hi! I have the APS3010H version of this. Identical except it has memory buttons. Watch out, as there are a couple of major design flaws. Firstly, it has two switchmode power supplies: one for the PSU output and another for the controller circuitry. The former has mains filter circuitry, but the latter has absolutely none, so it squirts bucket loads of RFI back down the mains. Even ferrites on the mains lead don't clean it up. Secondly, there is totally inadequate filtering on the output. Using an oscilloscope to probe anything connected with this supply is totally futile.
That's bullshit or you have a defective unit. I own the 120V 3A version of this unit from its original producer Wanptek. While the ripple output filtering isn't stellar, it's quite good, especially taking the price point in consideration. RF back swamping the line is negligible
Can anyone explain what the ground terminal is all about? Is this supply -30 0 +30? or 0 30? If it's the latter then how does the output relate to ground?
The question is if that 0 is mains earth reference or not. If it is not, and you connect it to something is, then there’s a potential between the two you likely don’t want.

You know those wires do pull apart to reach the connectors better?

@@Orionrobots I agree , It sure came in handy when I found a bag of 5 MM LED's of unknown voltages ...
How can you get it to generate more current than volts
If you attach a device that needs a lot of current, it would generate more current, up to a limit. There may be a constant current mode, but if the device has a large enough resistance then it may not be able to adjust voltage enough to make that current. It has a voltage limit of 30v.

I'll put that in the list - it would be handy to see what those look like too.
Thanks, id also ask if its proportional regulated fan or is it on/off like aps models?
@@Boz1211111 having bought one (WPS3010H thanks to this video), mine appears to on/off.....or I am only triggering the first threshold level
@@JohnColemanesque same. ended up buying DPS series and its on/off as well. i very dislike that but seems like it would be the same if i went for the other series so i will prob keep it
I've looked at those before and it looks good in the video But I like the coarse and fine controls on a power supply......
The digital push knobs on this unit feels great and handy.

Looks liker a cheaper clone of the Wanptek which i think is the original with USB port and all. BUt thanks for video hope you liked the PSU
Thanks for watching!
The Wanptek don't have the usb port as well. They are the same product, same manufacturer. And its not cheaper... it's the same price.
@@corinasechelariu1307 you're answering a 3month old post. The price was different back then atleast in my country ;)

Hmm - that's something to test in a subsequent video...
@@Orionrobots Hi, did You test it?
Hi... What size is the output post plug?
That is something I can measure or check - perhaps in a next video?
Hi bro
Can it be used in the repair of mobile phones!?
If you require a reference voltage for testing the phone, then yes. However, with this particular type, I'd be ware of that startup voltage!
@@Orionrobots
Thanks bro

Is it "review" ? Why don`t you tear it down ?
I've done the occasional teardown, but mains power supplies are an area I'd prefer not to tear down, due to how dangerous they are inside.
Can anyone explain what the ground terminal is all about? Is this supply -30 0 +30? or 0 30?
If it's the latter then how does the output relate to ground?
Ah I just heard it near the beginning of the video - 'single output'. Not a lot of use to me then. Still don't get the ground terminal though.
The question is if that 0 is mains earth reference or not. If it is not, and you connect it to something is, then there’s a potential between the two you likely don’t want.
Hi are you still happy with Power Supply?
Hello, I've been using it to test and power projects, like this one - ua-cam.com/users/shortshieLF3K6hrs
