Servo Controlled Voltage Stabilizer
In laboratories and Industries where precision supply voltage is essential to avoid damage in costly equipments and instruments, use of servo controlled voltage stabilizer are recommended. This type of voltage stabilizer provides desired output voltage, either in single phase or three phase with a minimum of variation i.e. ±1% with an wide input range starting from 90V-265V in the lower side & 220V-290V on the higher side for single phase stabilizer & 160V-500V in the lower side and 380V-500V on the higher side for 3Phase variety as per customers specification.
