ABB UNITROL 1010-1002 3BHE035301R1002 Automatic Voltage Regulator

Product Description

ABB UNITROL 1010-1002, part number 3BHE035301R1002, is a Profibus communication sub-module of ABB UNITROL 1000 series compact excitation regulator (AVR, Automatic Voltage Regulator), designed for brushless excitation control of synchronous generators. The main UNITROL 1010 is a low-capacity excitation controller with rated excitation current of 10A, supporting voltage regulation, limit protection and grid paralleling monitoring. This sub-module expands Profibus-DP communication, enabling data exchange between the excitation unit and DCS / PLC systems. It is widely used for power plant excitation cabinet retrofitting and spare parts replacement. This model is obsolete, available mainly as new surplus stock, used and refurbished units.
