DC Power Supply Variable(0-30 V 0-5 A), Eventek KPS305D Adjustable Switching Regulated Power Supply Digital, with Alligator Leads US Power Cord

This is a great little power supply. I really like it. I will probably buy another one.

The media could not be loaded. Pros: Good value. V/I limiters. Accessories.Cons: 300W max output? Likely not.I figured it was time I get myself a benchtop power supply instead of using these wall plugs that I have.Most reviewers did say the knobs are a challenge to use and I agree. The fine and coarse are not what you expect in terms of precision. So having a multimeter handy is at the very least a must have.Along with the multimeter it hit 5V, 12V, and max with no issue - max it can do seems to be 31.54V. When set to 0V and then discharging the output caps you get 2.5mV.When you power it off from max it takes about 40sec to get to 100mV. To get to max from off is less than 3sec.The current limiter seems to work fine. You can see picture I tested it at 10A. My fuse isn’t working so I can’t really verify if it’s truly 10A. Considering that the voltage wasn’t too far off I’d say it’s accurate.I don’t know what the maximum power output is and the manual doesn’t give a clear indication other than the range. I posted a question and maybe the seller will respond. You can search for “maximum power output”. So is it truly 300W? Unlikely, since it small.It comes with a few alligator clips which is very much appreciated.Overall, I’d say this is great for home use and if you’re purchasing this then most likely you already have a DMM to go with it. Just be aware we/I don’t know the max power output.*Update* Seller responded that it is 300W. I need find some beefy resistors to test it out someday. Will update when I get to it.

The media could not be loaded. The unit is great overall. I really liked the ability to have 10amp output, as I do a lot of low-voltage, high amperage projects like flashlights, motors, ect. The unit comes with two pairs of clips where both ends are alligator, which I find useless, so I spliced on a JST connector to one of my two which works much better than alligator clips. The display is nice and bright, easy to read and controls and display are understandable.However, there's a major annoyance with the voltage adjustment. The "coarse" adjustment is super sensitive, like a tiny movement goes up a volt. This is really bad when I'm trying to test between 3-5v but 5.5v will destroy the device. The fine adjustment on the other hand only has a swing of about 0.2v, which isn't enough for really testing how circuits respond to a battery draining from 4.2v down to 3v. If the coarse was not as sensitive and/or the fine had a larger swing I'd be totally happy with this unit and would give it 5 stars.If you really want the 10amp output (as I did) and don't want to spend 100's, then be prepared to make your voltage adjustments BEFORE plugging in your electronics as otherwise you can fry them. Otherwise if you can get by with 5amp or less output you might consider a different unit, one that has infinite spinning dials or digital increments so that the adjustment is a lot more precise. If you are only using your unit for a single set voltage and don't change it at all this unit will be the best.PS if anyone knows if it's possible to replace the coarse/fine voltage adjuster pot with one that has less or more resistance to make it less/more sensitive to avoid this issue, please respond!

If you work in and automotive, motorcycle, or any type of motorsports or electronics repair shop you should own an adjustable DC power supply. Or if you're just into electronics and like to tinker like me then an adjustable DC power supply will definitely come in handy.I already own a larger adjustable DC power supply which I really like and use all the time. But I find that I am carrying it from my gadget room down to my garage on a regular basis and decided to buy another. What drew me to the Eventek KPS305D Adjustable power supply was that it was small and it was inexpensive, especially after "clipping" the discount coupon that was available at the time of purchase.It arrived looking and functioning exactly as shown and described by the seller. I hooked it up to a project and measured voltage and amperage output and my meter mirrored the readings on the Eventek KPS305D Adjustable Power Supply. (see pic below)I also tried different voltage and amperage outputs using both the "course" and "fine" adjuster knobs and was quickly able to dial in the desired outputs. The supplied power leads are just average, but will most likely work on most applications that I ma using this for.So far I like this adjustable DC power supply. If I experience any issues I will update this review.I've also included a picture below with some extra measurements included.

I bought this for bench flashing ECU’s. I have a setup at my shop that I built the power supply for but wanted something clean and compact for when I rarely flash the hardware at home.I set constant current for 1.5amps and voltage at 13v. I never even adjust voltage while powered on. It worked great 3 times (total of maybe 45 minutes) then the forth time I switched on and the amperage shot up well past 1.5amps and kept going. Before I could power it down the power supplies fuse blew and ecu was fried. Now every replacement fuse blows immediately.Upon further research I found how common the boards in the power supply fail. Most likely cause is transformer inrush current.

Il fonctionne très bien j'apprécie
