ABB 3BHE014557R0003 UNITROL 1000 Excitation Control Module

ABB 3BHE014557R0003 (UNITROL 1000 Z.V3) is a high‑performance digital excitation control module from ABB, integral to the UNITROL 1000 family 

for synchronous machines (100kVA–80MVA). It delivers precise automatic voltage regulation (AVR) and reactive power control, widely deployed in hydropower,

 thermal power, marine, diesel‑electric locomotives, and industrial drive systems.

Key features include:

Core Control: Regulates generator terminal voltage and reactive power, ensuring stability under load variations and grid disturbances.

Industrial Grade: Designed for high‑vibration, harsh environments with robust mechanical construction and reliable field‑proven performance.

Flexible I/O & Communication: Supports multiple I/O points, RS‑232/485, CAN, and Ethernet, enabling seamless integration with SCADA/automation systems.

Diagnostics & Connectivity: Integrates with CMT1000 tool for local/remote configuration, monitoring, and firmware updates; equipped with LED indicators for status/alarm visualization.

Ideal for new installations and retrofits, this module ensures reliable power generation and system stability. We supply new, original, and refurbished units with full warranty and global fast delivery.
