Digital Voltage Stabilizer
The importance of the use of servo voltage stabilizer (single and three phases) with sensitive electronic & electrical equipment is well known. No one likes to risk the life of costlier appliances, CNC machines, electrical equipment, motors 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. SERVOKON Servo Voltage Stabilizer have designed to give a constant output voltage for single as well as three phase applications with stability +- 1%. the efficiency has as 98% or more.
Out put 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. Therefor use of servo voltage stabilizer saves power and reduces MDI. The microprocessor control makes operation flaw less.
