UFC921A101 3BHE024855R0101

Product Description:

The ABB UFC921A101, with order number 3BHE024855R0101, is identified as an INT-2 Board Varnished designed for use in various ABB industrial control systems, particularly within ABB variable frequency drives (VFDs) and the UNITROL 5000 excitation system for generators. It acts as an interface board with a varnished coating for enhanced protection against moisture and contaminants, increasing its durability and reliability in diverse industrial environments. In VFDs, it likely plays a role in power supply control and managing the motor control electronics for regulating speed and torque. In the UNITROL 5000 system, it’s a key component of the automatic voltage regulator (AVR), controlling the generator’s excitation current to regulate voltage and reactive power.

Key Features:

• Interface Board (INT-2): Facilitates communication and control within ABB systems.
• Varnished Coating: Provides protection against moisture, dust, and other contaminants.
• For ABB VFDs: Involved in power supply and motor control.
• For UNITROL 5000: Part of the Automatic Voltage Regulator (AVR) for generator control.
• High Reliability and Performance: Designed for demanding industrial applications.
