Servo Voltage Stabilizer

Servo Voltage Stabilizer (single and three phases) are used with sensitive electronic and electrical equipment like CNC Machine, electrical equipment, motor lab equipment, Medical Equipment etc, by connecting AC Voltage which is not stabilized and dips at one point of time and at other point of time rises to very high value. Voltage Stabilizer are designed to give a constant output voltage for single as well as three phase applications with stability of +/- 1% and efficiency as high as 98% or more.Output voltage stability of Servo Voltage Stabilizer allows the optimum drawing of the current by load and as such no extra electrical power is consumed at low as well as high voltage. Therefore use of servo voltage stabilizer saves power and reduces MDI.
