ABBUNITROL 1000 3BHE014557R0003 complete set is a turnkey digital excitation control solution developed by ABB for synchronous generators and synchronous motors, covering all core hardware and supporting software required for standalone operation. The core control unit 3BHE014557R0003 features a 32-bit 100MHz dual RISC processor architecture, separating real-time excitation control and data communication tasks to avoid operation delay under heavy load fluctuation. The full configuration contains main AVR motherboard, excitation power output module, signal isolation terminal block, DC auxiliary power adapter, communication cable set, user operation manual and licensed CMT1000 PC commissioning software, all factory inspected and aged to eliminate early failure risks.

This unit realizes multi-mode intelligent regulation including constant voltage (AVR), constant excitation current (FCR), constant power factor and constant reactive power control, supporting bumpless mode switching without generator power fluctuation. Built-in comprehensive protection and limiting functions cover V/Hz overexcitation limit, maximum/minimum field current limit, PQ boundary limit, overvoltage, undervoltage and overheat protection, with non-volatile flash storage to record 1000+ fault event logs with precise timestamps for rapid troubleshooting.

It supports multiple standard communication protocols including Modbus TCP/IP, RS485 Modbus, CAN bus and Ethernet, enabling seamless connection with DCS, SCADA and remote monitoring platforms. The compact DIN rail mounting structure saves cabinet space, with wide environmental adaptability for -25°C ~ +55°C continuous operation, suitable for new power plant construction and old excitation system upgrade renovation projects. Fully certified to CE, UL and European ENTSO-E grid codes, it meets strict grid ride-through (FRT) requirements for global power grid access standards.
