Products Description
ABB 3ADT218437R0004 DCS400 DC Drive Main Control Board Unit
Feature & Principle
It is the core control board of DCS400 DC thyristor drive. It receives speed and current feedback signals, completes closed-loop PI regulation, generates trigger pulses for thyristor rectifier bridge. It supports parameter setting, fault recording and communication with upper controller, and provides overcurrent, overvoltage and overspeed protection logic.
