All electronic devices are generally designed to work within a particular voltage level. They can be damaged, sometimes beyond repair if a voltage fluctuation occurs. So expensive and important electrical appliances like computers, air conditioners, refrigerators and televisions need to be protected from this kind of fluctuation. That is where a voltage regulator or a voltage stabilizer comes in.

The absence of stable power supply cause breakdown of sensitive equipments thereby harming the work process. So to overcome these difficulties we manufacture these premium quality Servo Controlled Stabilizers.

We offer a unique range of economical but precision Air Cooled & Oil Cooled

servo voltage stabilizers

. It is a reliable product for stable power supply. These are being manufactured by using high graded raw materials.

Our Three phase and Single phase servo controlled voltage stabilizers, are well known for its reliability & ruggedness, These are used where a precision voltage is required.
