I have 2 ABB Power plates from a 75 kW 380v industrial AC controller.
PP30012HS
This is the only relevant document I could find in my search: http://www.wqyd.com.cn/pdf/pp30012hs(abbn)5a.pdf
Also from this machine:
Thyristor/ Diode Modules skkh 132/16 e
http://www.rell.com/resources/RellDocuments/SYS_24/609903.pdf
Are any of those components good to work with for a DC controller or should I just put them on ebay?
