Product Overview

• Part Number: GVC736CE101, full order code 3BHE039203R0101
• Brand: ABB
• Type: All-in-one thyristor trigger power assembly (thyristor + drive trigger board integrated)

• FunctionCore power switching component for generator UNITROL excitation rectifier cabinets and ACS6000 medium voltage inverters. It receives optical trigger signals from main control boards to complete AC-DC rectification. It adjusts excitation current of generators and output voltage/frequency of medium voltage drives. Built-in signal conditioning, fault detection and overcurrent protection circuits monitor thyristor working status in real time, cutting off pulses when abnormalities occur to protect power devices. Double-sided water cooling structure dissipates heat efficiently for stable heavy-load operation.
