This digital stabilizer has a wide input voltage range, which allows the stabilizer to deliver safe voltage to your appliances, irrespective of the voltage from main power source, and the voltage going out of the stabilizer to your appliance. It also has a overload protection feature, which ensures the tripping of the circuit breaker when the stabilizer is overloaded to prevent damage to appliances and stabilizer. The circuit needs a manual reset, when the overload condition is eliminated. The cooling fan helps to cool the coil of the main transformer during operation, thereby helping to prolong the life of the stab. The 2000VA stabilizer is recommended for medium and large freezers or refrigerators, and all types of electronic home appliances.
