LT Servo Voltage Stabilizer

Automatic Voltage Controller (Balanced Type) System voltage is higher/ lower than the rated voltage, the following consequences have been observed, The sensitive CNC machines require a fortune to be invested, are prone to breakdown even due to slight variation in voltage. The fluctuating voltage is hazardous to expensive cards of these HI-tech machines. 

With the fluctuating voltage the quality of the end products say in moulding plants, welding plants etc. will not be constant thereby increasing the rejection rate. Voltage on the higher side drops the power factor at least by square function. Low power factor decreases the overall system efficiency.

In electric motors (particularly smaller capacity upto 7.5 H.P.), The higher current requires higher setting of over load relay to avoid the frequent tripping of motors. Higher setting of 5551155 relay has very less safety margin against single phasing and mechanical faults. For example, during any fault, suppose the relay setting is 15-20% higher than actual operating current, then the relay will take 4-6 minutes to trip. The motor can not withstand the high current for such a long firne and in most cases it bums out before the motor trips. 

Universal's servo voltage stabilizer is meant to overcome all the above problems by maintaining steplessy a constant level of voltage irrespective of the fluctuating power supply system.
