Hi Eddie,
I ordered one of these 3 months ago since I also liked the 3 memory settings and output power indication. Did find that the turn on rise waveform is non-monotonic and the output noise level is much too high especially for audio work. Radiated emission is also horrendous. When you have an AM radio nearby and turn on this power supply you can "hear" all the noise being emitted. Using a sniffer probe we can find the radiated emission is all coming from the front panel PCB with a STM8S10 SMU. Didn't like how they positioned the chassis ground post in between the + and - posts such that a 3/4" test adapter can be used when needed. Last but not least, there are (4) 1W SMT current sense resistors used and when the output is set to 24V or higher the temp measured on these resistors were well over 100 degC (hot!). As these are soldered right on the PCB, discoloring of the PCB shouldn't take too long to occur. For these reasons and some others not mentioned here I decided to return the PSU. For me it was one of the worse PSUs ever evaluated and I'm surprised Kaiweets is reselling this (unpronounceable) brand.
Wow - thanks for this great feedback! I'll have to look into this and see if there's a good fix. I like the size and the setting work great. I like all the digits and ease to get the voltage that I want, but I have been having one crummy month and haven't had the chance to deep dive into this PS. I appreciate your great feedback!
Hi Eddie, really like you comments on the power supply.🎉Thank you for the info.😁
You bet! Thank you!
I have one of those, come in handy for general use
What is its basic specs, such as output noise and regulation.
Very useful information thanks ❤❤❤
Thanks so much!
Nice power supply
Thank you!
I have a multimeter from kaiweets! Great quality for sure.
Anyway, i built my own DIY 0-50V 10A 500W variable power supply. The only thing i really envy is the nice display and the memory thing...
Nice video, keep it up!
Thanks for your great feedback! Great project - thanks for sharing!
Hi Eddy
I dont think it is a Kaiweet, the front says:
Wanptek😂😆😉😍
I got three wanptek, and I just ordered two like this yesterday, so I can build a plus-minus supply. I am very happy with wanptek, and even more after they changed the controll. Despite it having a fine knob it is absolutely hell to adjust precisely..
PS what is the correct name or term for a plus/minus supply?
Thanks so much! You are correct (I believe) Kaiweets just sells it as well with the Wanptek name. Viewers here get a 15% discount for Kaiweets just use the KA15 code.
The fine tune knob on mine you can push it in to move the control to any digit and adjust, so mine is easy to get precise voltage outputs.
The Plus and Minus setup using 2 power supplies is simply a series power supply connection with the middle terminals that connect being your zero volt ref in relationship to the top (positive) and the bottom (negative) voltages. Make sense? BTW - great way to get 2 rail voltages for amplifiers;) I did a video on this using two Kaiweets PS: czcams.com/video/zWNxDlWrafw/video.html
Is better than nothing loved it thank you

Thanks so much! I'll get a real video out very soon.
Hey, I just got mine like today as I'm writing this comment. I wanted to ask, can I have the fan always on ? Is there an option / hack to do so ? Because I like my electronics to always run cool :) Seems like this fan barely turns on...
Thanks for your feedback! I would think that you could modify it to keep the fan on. But, I think they did a nice job and this thing is really efficient, so I'm actually happy not to have the fan noise;)
@@KissAnalog Did you test to see the temps of the fets ? Are they cool ? Are they in parameters ? That's why I'm worried about.
What the power supply do when I touch the red and black wire when its 30v 5a? 😊
LOL - thanks! It will have no trouble protecting itself;)
@KissAnalog but when i touch the red and black wire on 30v 5a with fingers
@@KissAnalog😊
at 30 volts, nothing will happen. Unless you lick your fingers really good beforehand... then you will get some tingle out of it. :) @@nev11m
I just received the lesser WANPTEK DPS3010U that doesn't have memory buttons.
What do you use the green ground terminal for?
Thanks for your feedback. Yes this one with the memory buttons is very nice. It is on a 20% off sale so it is about $80: amzn.to/3XqjwZ1
The ground terminal can be used to tie your load to chassis/earth ground if that is desired. I almost never use that.
@@KissAnalog Ok thanks! Its so nice to have variable power so I can finally see at what voltage things turn on and off and how adding or subtracting resistance can change the required supply voltage !
Yes a variable power supply is almost a must for the bench;)
I prefer Riden power supplies.
At 3.6 volt 10 amp is possible
Yes it is ;)
What's the ripple look like Mr Analog?
Great question! I'll have to do a full review of this power supply. I have really like it so far.
Would this power a ham radio
I think it would if it takes less than 300 Watts. If you gave me the model number I could look it up.
Link please
Thanks for asking! amzn.to/3T2UsGX
It’ll fit nice in the trash.
LOL - It fits very nice on my bench and works fantastically! Why don't you like it? What do you like better?
Bought this PS and it's a POS. Turns on and all looks good but no output...DOA. Returning asap and I tossed the box..oh well.
That’s too bad. Mine works great and they have a 4.4 out of 5 stars with 286 voters, so not bad. Did you check the fuse on back? I wonder if it was a return?
@@KissAnalog Sorry Eddie for my less than acceptable comment. Just frustrated it didn't work out of the box. I checked everything a dozen times, just no go. Have replacement unit on the way. Apologies and thanks for reply.
Thanks for your feedback - and no worries. It is frustrating to get a DOA! Let us know how the new one works.
@@KissAnalog Hi Eddie, the new power supply works good. Impressive really for a low cost supply. The first one must have been a "fluke" 😉 I did replace the included cables with better 14ga silicone ones I made. All's good for now, thanks for your kind reply.
pls no shorts hyper annoying. thx
Sorry about that! I had a death in the family so I was using these shorts to fill in until I could spend the time on a real video. I am working on one now;)
@@KissAnalog very sorry to hear that. Please accept my sincere condolences for your loss.
All these new switchers are rubbish and noisy by my standards, can also do really funny things with high precision circuitry making you chase your tail when the source of the problem is the supply not your circuit.. it of course depends on what your doing with it..
Hi are you still happy with power supply?
Yes I really like this power supply:)
@@KissAnalog Thanks.
