should support up to 60v. On test with 40V power supply the load stopped to work. it is not possible anymore to change the load or switch it on or off (it shows new values on the LCD display, but the output is short-cutted) Waste of money.

  • KKChan I had the same problem as you did. The problem is that there is an SS54 schottky diode across the current input (as protection) and its breakdown voltage is only rated at 40V. Anything above 40V will blow this diode. I changed the diode to a 1N4007 (not ideal but that was what I had) and everything works OK now.

  • KKChan My unit blew its MOSFET with input current at just 5A. I had to change the MOSFET to an IRFP460 and then it works fine. I submitted my review but Banggood never published it. I guess they want only good reviews. I used to submit glowing reviews with "highly recommended" rating when I received good items from Banggood. But I don't bother now.
