Product Overview

• Part Number: GCC960C103, full part code 3BHE033067R0103, accessory code 3BHE033068P106
• Brand: ABB, Origin: Switzerland
• Matching Equipment: ACS2000 medium voltage inverter
• Type: Phase signal conditioning & optical interface board

• FunctionServes as signal intermediate board between ACS2000 main control unit and high-power power units. It collects three-phase voltage and current signals for phase synchronization and closed-loop calculation. It converts control commands into optical fiber trigger pulses to drive power semiconductors. It monitors phase imbalance, overvoltage and overcurrent faults, sends fault feedback to the main controller for protection interlock, guaranteeing stable rectification and inversion of medium voltage frequency converters.

Core Features

1. Fiber-optic signal transmission completely isolates high voltage and control circuits, strong anti-interference in high-voltage power cabinets
2. Precise multi-channel phase sampling, supports phase locking of multiple power cells for multi-level medium voltage drives
3. Built-in hardware fault judgment circuit, timely capture phase loss, phase deviation and power unit abnormalities
4. Conformal coated PCB, dustproof, moistureproof and oil-resistant, adapts to long-term operation in metallurgy, mining and chemical harsh environments
5. Standard card slot plug-in installation, supports hot swap, convenient on-site replacement without long system shutdown

6. Status indicator LEDs on the board for fast positioning of communication loss, signal failure and trigger anomalies
