Main Functions Real‑time monitoring of medium‑voltage drive DC‑link bus voltage. Fast trigger crowbar thyristor under DC‑bus over‑voltage fault condition, release fault energy and clamp bus voltage. Provide hardware‑level fast over‑voltage protection for drive power‑semiconductor modules. Collect crowbar circuit working status and fault feedback signals, transmit status information to drive main controller. Front‑panel LED indicators display power‑on status, trigger‑action status and hardware fault alarm codes for on‑site inspection. Hardware self‑diagnosis detects board internal circuit abnormality and trigger‑loop fault, upload fault alarm codes to drive main unit. Parameter setting and fault diagnosis are completed by ABB drive commissioning tool.

Installation Requirement Plug‑in installation inside ACS2000 / ACS5000 medium‑voltage drive cabinet. High‑power main‑circuit cables and weak‑signal control‑wiring shall be strictly separated. Ensure reliable cabinet protective grounding. After board replacement, confirm full part‑number GDC801A101 / 3BHE024747R0101 matches original drive configuration, restore complete drive parameter settings. Perform power‑on self‑test, crowbar trigger‑function simulation test and internal signal‑loop verification. Different hardware revisions cannot be directly interchanged without parameter adaptation. Do not put into service until no hardware self‑diagnosis fault alarm exists.

Typical Application Scenarios Crowbar protection spare‑part for ABB ACS2000 / ACS5000 medium‑voltage AC drives, widely used for large‑power fan, pump and compressor motor drive‑system maintenance in mining, metallurgy and power‑plant auxiliary‑equipment fields.

Key Features

1. Dedicated Rigi‑Crowbar drive protection board for ABB medium‑voltage drives, provides microsecond‑level fast over‑voltage protection for DC‑link loop.
2. Conformal varnish coated PCB, suitable for humid and corrosive heavy‑industrial site environment.
3. Integrated status monitoring and self‑diagnosis function, convenient for on‑site fault location.
4. Cabinet‑internal plug‑in structure, convenient for on‑site replacement and maintenance.
5. Strict full‑part‑number matching shall be observed during spare‑part replacement; cannot be substituted by ordinary control boards.
