The importance of the use of servo voltage stabilizer 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. C&S Servo Voltage Stabilizer have been designed to give a constant output voltage for sis well as three phase applications with stability + 1% , the efficiency has been maintained 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
