Product Background

3BHE024747R0101 is a dedicated crowbar‑drive control printed circuit board for ABB ACS2000 / ACS5000 medium‑voltage VFD (2.3kV‑6.6kV) series high‑voltage inverters. It is installed inside the medium‑voltage drive cabinet, as the core control unit for the crowbar protection circuit (Rigi Crowbar) of IGCT power semiconductors. This board is a critical spare‑part component for medium‑voltage drive systems. The original ABB production is discontinued (EOL); only original surplus stock, refurbished or aftermarket compatible spares are available in the industrial spare‑parts market. It cannot work as a standalone device; it must be mounted inside ACS2000 / ACS5000 drive chassis to operate.

Main Functions

1. IGCT Crowbar trigger drive control Generates accurate trigger drive signals to activate the crowbar protection circuit. When DC‑bus over‑voltage or fault conditions occur, it triggers the crowbar circuit to discharge the DC‑link capacitor, protecting IGCT power devices from over‑voltage breakdown damage.More products: www.plcva.com
2. DC‑bus voltage monitoring & fault detection Continuously samples and monitors DC‑link bus voltage of the medium‑voltage inverter. Detects over‑voltage, abnormal voltage surge and hardware circuit faults.
3. Isolated drive signal output Provides electrically isolated drive pulses to the crowbar thyristor / IGCT power devices, separates low‑voltage control logic from high‑voltage power main circuit, suppresses strong electromagnetic interference.
4. Fault status feedback to main controller Transmits crowbar‑circuit status, fault alarm signals and trigger‑event information to the main drive control unit, so the system can log fault codes and execute system shutdown protection.
5. Internal self‑diagnosis Performs real‑time health check of on‑board circuits. Reports hardware failures to the drive system for maintenance diagnosis.
6. Auxiliary power management Receives auxiliary power supply from the medium‑voltage drive system; manages power for crowbar‑drive logic circuits.
