UrduServo Voltage Correctors
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 an acute/ higher failure rate of electrical equipment such as bulbs, tubes, chokes, starters, 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 the input voltage is lower or higher than 230V (single phase)/ 400V (three phase) even for few hours a day, then you definitely require a stabilizer.
