AVR Voltage Regulator

Ascent’s AVR200 Series Automatic Voltage Regulator provides a stable output voltage supply for electronic equipment and is widely used in telecom base stations, CNC machines, computerized topography, printing machines, production lines, and other voltage stabilization applications.

•    Wide input voltage range

•    Wide load power factor range (resistive, capacitive, inductive)

•    Continuous operation and short time overload rated

•    Long life roller type carbon brush

•    Negligible wave distortion to output

•    Self-coupling transformer can be connected at the input or at the output of the DBW

•    Protection circuit (over/undervoltage and overcurrent with shutdown delays)

•    Vacuum pressure impregnation process for F or H class insulation of the magnetic components

•    Surge protection option is available on request

•    Multiple outputs or other output voltages are available on request
