Customer Review

I was for some time in search of a good adjustable power supply, which provides a sufficiently large range of voltage and amperage.

While rummaging in Amazon I came across this unit and was based on the few reviews initially a bit skeptical. Nevertheless, I decided to buy and now is this baby since yesterday with me in the shop and has some appliances and lighting elements (LEDs, etc.) supplied with power.

It's really quite large and especially difficult. A quick look inside after loosening the housing screws shows that this equipment has been processed very valuable. Outwardly, it looks a bit old-fashioned, however, but for the for purpose of does not matter. I have opened the device because any tiny particles flying around in the case and I wanted to see what it was. It has then been found, however, that at a thicker solder probably a little, I'll call it "solder balls" has flaked. However, the solder joints themselves are all OK After removing this Abplatzers rattling was gone.

Particularly positive:
- Very easy to read display
- Really finely adjustable voltage and current. For other power supplies you need here partly patience
- Quality workmanship and layout of all components inside the unit.
- Idle relatively quiet. Other devices sometimes whistle at high frequency

I am very pleased and can recommend this device clearly.

A drug that tastes delicious. Rank: 5/5
