Sylvan Voltage Stabilizer
Sylvan Voltage Stabilizer

Product Description:
Air Cooled & Oil Cooled

A Voltage Stabilizer is used to control a fluctuating voltage at input & still deliver an almost constant voltage, at the output. Sylvan’s Servo Voltage Stabilizers (SVS) are a very effective solution to voltage fluctuation problems that are a common phenomenon in power lines nowadays. Sylvan’s SVS are designed to handle a wide range of input fluctuations and still maintain specified output voltage within +/- 0.1% regulation. The output voltage waveform is completely distortion free and the regulation remains typically unaffected by the load power factor.

Installing a Voltage stabilizer at the mains will ensure a stabilized voltage is delivered to all your equipment and help you save energy (hence save the environment and save money) and increase the life of your equipment.

Available in Single Phase and Three Phase with both Air Cooled and Oil Cooled options.

Cost Saving Calculation:

An average industry site consuming ~250KVa can save upto Rs.1,80,000 in a year after installing a Servo stabilizer.*
