IECO Servo Voltage Stabilizer, Output Type : AC Single Phase, AC Three Phase, DC

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 air-cooled servo voltage stabilizers are suitable for small and medium capacity loads of 1-25 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. Depending on input voltage range, the stabilizer is either natural air-cooled or forced air-cooled. forced air-cooling is provided by directed air-flow fans fitted inside the stabilizer enclosure. 

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.
