Outdoor Voltage Stabilizers
Single & Three Phase - 6 to 500 kVA

  • Outdoor IP54 Single and Three Phase Voltage Stabilisers designed
    to maintain the mains voltage constant at all times.  

  • Based on our standard SES electro-mechanical stabilisers, OSES
    stabilsers offer high reliability, fast response and high output voltage

  • Housed in IP54 enclosures, OSES voltage stabilizers are ideal for
    most applications delivering no magnetic interference and being able
    to withstand high instantaneous overload conditions.

  • Wide Range
    Single Phase & Three Phase
    6 to 500KVA
  • Input Swing Range Available from
    ±10%, ±15%, ±20%, ±25%, (To Specify)
  • Output Voltage Regulation
    Accuracy ± 1%,
  • High Efficiency
    Better than 98%
  • Independent Phase Control Circuit
    Maintain each phase voltage stable,
    irrespective of load unbalance.
  • Soft Switch-ON
Ensure that the Voltage Stabiliser is at its
minimum before it commence full stabilization
