Product Description
BEMAC UST-201-D Automatic Voltage Regulator
The BEMAC UST-201-D is a high-quality Automatic Voltage Regulator (AVR) designed for use with brushless generators, particularly in marine and industrial applications. This robust half-wave phase-controlled thyristor type AVR is engineered to maintain a stable generator output voltage by regulating the exciter field current. It features built-in Under Frequency Roll Off (UFRO) protection, which reduces the output voltage in low-speed conditions to protect the excitation winding from damage. The UST-201-D is known for its reliability, precise voltage regulation, and durability, making it a trusted component for ensuring consistent power generation.
