What Our Customers Are Saying
- Well packed and fast delivered. I had to make the repair described here in "Questions & Answers" - pin changes in connector from the voltage regulation potentiometer. It is only problem of this power supply. Now I am very satisfied and I can recommend it if you are able to make eventually described modification. Besides this problem is this power supply really great and well made. Used multiturn potentiometer provides very smooth setting of output voltage. Output current is high enough for my purpose. The big feature is a compact size. Datel69,16/12/2021
- Gyorsan megérkezett (2022.01.01-én rendeltem, 2022.01.05-én megkaptam) a Csehországi raktárból. Hibátlanul működik. Amikor rendeltem, akkor nagyon jó akció volt rá, ami most már sajnos nincs. :-) fataca,05/01/2022
