Product Description

BEMAC UST-204-E

The BEMAC UST-204-E is a high-performance Thyristor-type Automatic Voltage Regulator (AVR) specifically engineered for use with brushless AC generators. This robust unit ensures a stable and consistent voltage output by precisely controlling the exciter field current. It features built-in under-frequency protection (UFRO) to safeguard the generator from damage during under-speed conditions. With its reliable solid-state circuitry and compact design, the UST-204-E is an essential component for maintaining optimal performance and power quality in a wide range of industrial and marine generator applications.

Technical Specifications:

  • Model: UST-204-E

  • Sensing Input Voltage: 220/440 VAC, 1 phase, 2 wire
