Detailed Working Principle
Our voltage corrector operates using a servo motor-driven variable transformer (Variac) along with a buck/boost winding. When there’s a shift in input voltage, a microprocessor quickly detects the change and activates the servo motor. This motor adjusts the variac to either add or remove voltage through the buck-booster transformer. The outcome? A stabilized output voltage that stays within ±1% no matter how much the input fluctuates. You can monitor real-time input and output values on the voltmeter, and if the input voltage strays outside the set limits, an alert buzzer will sound. Plus, if there’s an overload or short circuit, the system automatically pauses power to protect both the equipment and the device.
