I have bought the 32V 5A version. The metal case is grounded proprerly. The user interface is a little bit confusing at th first run because of only one rotary encored but namageable. The current measurement shows 0A at output current up to 12 mA. However the short current protection works fine. I can recommend the product.
great power supply. Perfect choice for beginers but it is having it's place also in a profesional workshop.
Great power supply for the price. Works well, easy to use. Plenty of power for such a small unit. I recommend replacing supplied power cord with a proper one. The cord that i got had very thin wires made of some stiff material that is definitely not copper.
