Six protection functions to achieve safe voltage regulation 1. Overload protection When the load power reaches 120V%, the voltage stabilizer will automatically protect and cut off the output. 2. Overvoltage protection When the output voltage exceeds 265V, the overvoltage indicator lights up and cuts off the output. 3. Undervoltage protection When the output voltage is lower than 175V, the undervoltage indicator lights up and the output is cut off. 4. Delay protection The delay protection starts the voltage stabilizer and waits for 3 seconds before it can work. 5. Phase loss protection If one or two phases of the three-phase power are missing, the voltage stabilizer cannot be started. 6. Over temperature protection When the temperature is too high, the voltage regulator automatically protects.
