Northstar “Honeycomb Series” MVR-D50KVA/AZ Single Phase AVR 50KVA with TVSS Input 220VAC ±20% Output 220VAC Automatic Voltage Regulator for Industrial

The Automatic Voltage Regulator is composed of a voltage regulation system, servo motor and automatic control circuit. When grid voltage is unstable or when the load changes, the automatic control circuit would sample, amplify and send a signal to control the servo motor to adjust the position of the roller brush on the voltage optimizers system, and regulate the output voltage to the rated value finally.
Our products can offer high capacity and high efficiency. They are easy to operate, require simple maintenance and offer high reliability.

The UNITs can match any load, especially unmanned operation of equipment in telecommunication centers. The UNITs provide stable output voltage supply for electronic equipment such as telecom base stations, CNC machines, printing machines, production lines and others.
