AC Voltage Stabilizers - Single & Three Phase  1 to 800 KVA

  • Cost Efficient Electromechanical / Servo  type Single and Three Phase Voltage Stabilisers
    designed to maintain the mains voltage constant at all times.

  • Offering high reliability, fast response and high output voltage accuracy,
    SES voltage stabilizers are ideal for most applications delivering no magnetic interference
    and being able to withstand high instantaneous overload conditions.

    Bypass control switch
    Voltmeter / Selector switch (Internal)
  • Compliance with International Standards
    BS EN50081-1;2/IEC 61000-4-3;4
    BS EN5490/IEC 60529
  • CE Conformity
  • Cost Efficient Voltage Stabilisation Solutions with Fast Speed of
    Response and High Output Voltage Accuracy.

  • Ashley-Edison’s Model SES Voltage Stabilisers are designed to
    maintain the  mains voltage constant all the time. Their electromechanical
    / servo design will electronically ensures the mains voltage remains
    stable should the incoming mains voltage drift high or low.  

  • They are characterized by the high efficiency and are  completely
    unaffected by power factor, load and frequency  variations.  

  • SES Voltage stabilisers can withstand high instantaneous overloads
    and do not create any magnetic interference.

  • Compact in size, quiet in operation, these voltage stabilisers are very suitable for  indoor
    use and can be located near to equipment without causing any magnetic disturbances to
    the equipment.
