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
