Product Details

The ABB 3BHE035301R1002 UNS0121A-Z,V1 UNITROL 1010 is a compact original ABB Automatic Voltage Regulator (AVR) for synchronous generators and motors. As a critical ABB excitation control spare part, this ABB UNITROL 1010 AVR delivers precise voltage regulation and reliable excitation control, supporting multiple control modes and built-in protection functions. It features Ethernet, USB and Modbus communication interfaces, offering great system compatibility and convenient parameter configuration.

Product Uses

This automatic voltage regulator is mainly used for excitation control and voltage stabilization of synchronous generators and synchronous motors. It is widely applied in thermal power plants, hydropower stations, diesel generator sets, marine power systems and industrial power generation projects. It can stabilize output voltage during load fluctuation, improve grid stability and protect generators from abnormal operating conditions. When the original excitation controller fails or ages, the ABB UNITROL 1010 AVR can be used as replacement spare hardware to restore generator control performance and reduce power system downtime.
