Hi All
Just want to give a fair warning about this company.
brought a one of there "big" psu (CSY600-6) almost a year ago.

i did not put much thought in that, shit can happen. they send me a new power board.
Got it assembled and started the test of the psu when i got to around 300v it blew up again...
so i got a closer look and realised they used 2 x 0603 resistors as the input divider for 600V, wtf :/
They obviously don't know what they are doing...
I still don't have a working psu and they don't respond to me anymore.
I just want to know how to calibrate the unit, apparently a hard question to answer.
$1000 down the toilet!...
