Hello

 

we want to replace the analog controller BHEL 400Amps, dual converter ( Simadyne) with digital controller using the existing power section( thyristors). What factors are to be considered for this. Is it possible to use ABB make DCS500(250Amps) controller for this. Pl give your valible suggessations.

Hello pslakhe

 

ABB make a DC upgrade "kit" called called the DCR500, this is a kit that interfaces the DCS500 digital electronics to an existing drive power electronics ie thyristors. But you need to discuss your application with your local ABB drive people. From the reading I have done, the standard kits are to replace old ASEA Tyrac8 and BBC Veratron drives.

 

I think however, you will find that it will be more cost effective to simply replace the entire drive 400Amp is a small drive.

 

Cheers
