UFC789AE 38HE014022P102
ABB UFC789AE 38HE014022P102 Excitation Control Board
Product Description
The ABB UFC789AE 38HE014022P102 is an excitation control board designed for applications such as synchronous motors, generators, or large – scale variable – frequency drive systems. It plays a crucial role in controlling the magnetic field (excitation) of these systems.
This module features precise magnetic field current control with a PID regulation accuracy of ±0.5%. It also offers automatic voltage regulation (AVR) to maintain stable output voltage. In terms of protection functions, it includes over – excitation/under – excitation protection, out – of – step protection, and magnetic field short – circuit detection, which enhance the reliability and safety of the system. In addition, it is equipped with communication interfaces that support Modbus, Profibus, or ABB – specific protocols, enabling seamless integration with other devices in the industrial control network.
