Automatic Servo Voltage stabilizer

The Automatic Servo Voltage Stabilizer is a high performance unit that keeps the voltage at a set value without interruption. A fully automatic control loop reacts in less than 10 ms and changes the voltage at up to 105 V each second. A variable speed high torque DC servo motor drives the regulating transformer smoothly - the output stays level even when the supply or the load is unbalanced. High-grade core laminations plus electrolytic-grade copper keep losses low - efficiency is normally above 98 %. The unit is fitted with overload cut off, over-voltage and under-voltage alarms and a manual bypass switch. Rugged industrial construction uses plug in glass-epoxy cards for quick servicing but also long life. After any fault trip the stabilizer resets itself and continues to hold the voltage steady protecting sensitive equipment.
