  • So far so good.

So far so good.

  • A nice bench power supply with some limits
Style: 5 Amp Max.
This power supply is a good unit for beginners, its footprint is pretty small on a desk, it is silent when used with small draws, pretty accurate in readings whether voltage or current drawn but it lacks the possibility to set a current limit along with a voltage setting. That means this unit can only do constant voltage or constant current, not both at the same time which, for some applications is a serious drawback. My unit is 2 years old and still performing well, though I did not mishandled it or pushed to its limits very often. As it is a switching power supply, expect some capacitance especially when powering of (power fades slowly) and powering on (power surges suddenly with over voltage ). ... show more

  • Other than some QC issues, great little PS
Style: 5 Amp Max.
For the price its great. the only issue i had was when it arrived, it rattled. so i popped it open and found a rouge screw bouncing around inside. it was a screw intended to hold the vertical PCB to its mounting plate, it had likely not been tightened when it was assembled. I put it back in and while i had it opened i went ahead and tightened all the other screws and bolts under the cover just to be on the safe side. That issue aside, its a great little unit. it will be more than enough to do what i need it for. ... show more

  • Works fine and very compact.
Style: 5 Amp Max.
I am getting back into electronics as a hobby and I was looking for a cheap variable power supply. This almost fits the bill but I wish I would have paid a little more and gotten the 10 amp version. I thought 5 amps would be plenty starting out but just a string of programmable LED lights draws more current than 5 amps. If you are absolutely sure that 5 amps is enough for your needs then by all means get this but otherwise spend a little more and get at least a 10 amp power supply. ... show more

  • Good until you want a smooth signal
Style: 5 Amp Max.
Great power supply, until you start making things that don't work when noise is introduced. This supply produces a super noisy signal, and it's enough to trigger the brown-out state on some microcontrollers. Microcontrollers just so happen to be the majority of what I work with, so I ended up tearing this unit down for parts. ... show more

  • Power delivery is accurate and reliable. Power supply was shipped with one foot missing.
Style: 5 Amp Max.
I used this power supply for medical research flow regulation, and it has worked very well. The only negative was that it arrived with only three of four feet and no identical part replacement was available. Amazon help offered reimbursement for aftermarket feet, none of which really fit. Quarter inch thick stick-on rubber foam stabilized it. It's quite a good power supply for the price. ... show more

  • Precise voltage control.
Style: 5 Amp Max.
I purchased the power supply for electronics experimentation. I have not yet started to use it but L tested it's operation and liked it very much. I am more 5 pleased with the purchase.

  • Excellent value
Style: 5 Amp Max.
I will be using this for etching, plating, and the occasional electrical project. It was as described, and functions well. Smooth adjustment potentiometers, crisp and easy to read display, and good build quality. It regulates well and is accurate. A good value over all. So far I have no disappointments, and if it proves itself over time I would not hesitate to purchase a second higher amperage unit. ... show more
