Servo Voltage Stabilizer

Servo Voltage Stabilizer Single PhaseServo Voltage Stabilizers Three Phase
The Servo Stabilizers are ideal choice for used as Mains Voltage Stabilizer, they provide continuous and precise voltage regulation without any break in supply. AULTEN  Stabilizers are highly power efficient having less than 2% no load losses.

If your unit is suffering from low/high/unbalanced voltage, you need to install a stabilizer soon. Industrial units having acute/ higher failure rate of electrical equipments such as bulb, tubes, chokes, starter, contractor coils, motors etc., should verify that it may be due to voltage variation (esp. High voltage). You may note down hourly readings of incoming voltage for a few days continuously. If you find that input voltage is lower or higher then 230V (single phase)/ 400V (three phase) even for few hours day, then you definitely require a stabilizer.
