Product Detail

ABB 3BHB004027R0101 alias GVC700AE01 fiber optic IGCT drive board, applied to ACS6000/ACS8000 MV drives and UNITROL excitation cabinets for pulse driving and fault monitoring.

Product Overview

Part Number: 3BHB004027R0101, alias official model GVC700AE01
Brand: ABB, Origin: Sweden
Matched Power Device: Press-pack IGCT such as 5SHX0445D0001; supporting auxiliary boards 3BHB003152P201, 5SXE05-0155
Type: IGCT dedicated fiber optic gate drive control board
FunctionServes as core driving unit between main control system and IGCT power devices of high-power converters. It receives fiber optic trigger signals from upper control boards, amplifies and converts signals into gate driving pulses to switch IGCT on and off. It integrates real-time hardware fault detection, collects working status of power devices, feeds back overcurrent, overvoltage, overtemperature and trigger abnormal signals to main control unit for protective interlock. It cooperates with snubber circuits to suppress high-frequency voltage spikes, guarantee stable rectification and inversion of medium voltage inverters and generator excitation rectifier loops.

Core Features

Full fiber optic signal transmission, complete electrical isolation between high-voltage power side and low-voltage control side, excellent anti-interference performance for high-voltage power cabinets
Integrated pulse shaping, fault diagnosis and feedback circuit, closed-loop drive control with high response speed and stable trigger waveform
PCB with conformal coating, dust-proof, moisture-proof, oil and corrosion resistant, adapting long-term heavy-load operation in power, metallurgy, chemical harsh environments
Multiple onboard LED indicators for power supply, trigger signal, running status and device faults, convenient quick on-site troubleshooting
Standard fixed layout matched with press-pack IGCT power stack, reserved cooling installation position for easy assembly and replacement
Built-in surge filtering and anti-jamming circuit, low malfunction rate under frequent high-current switching
