Servo Voltage Stabilizer

Home Products Servo Voltage Stabilizer

Single Phase Oil-Cooled

Servo Voltage Stabilizer is meant to correct Low or High Mains Voltage and maintain the Load Voltage at ± 1 % of 230 or 240 Volts. Voltage adjustment is actuated by a combination of Auto-Variable and Series Transformers by adding or subtracting a small voltage to Incoming Mains, thereby achieving a constant output voltage.This action is continuous, without any break, and is effected through a Micro-controller based Control Mechanism.

Single Phase Oil-cooled Servo Voltage Stabilizers are suitable for Medium to High Capacity loads of 5-350 KVA. These Voltage Stabilizers can be installed at domestic or commercial establishments to provide comprehensive protection to the Whole House / Establishment, thus saving sensitive equipment from damage due to Mains fluctuations 24x7 365 days.

Besides providing protection, Servo Voltage Stabilizers installed on Mains improve Power Factor and reduce Energy Bill wherever Mains is beyond ± 5% of 230 / 240 Volts. If there is higher deviation in Mains Voltage, substantial saving in Energy Bill is realised by installing the Servo Voltage Stabilizer at Mains itself. Details are available on request.

ieco® Servo Voltage Stabilizers provide trouble free service year after year without any particular maintenance.
