Can I Continue To Use The Voltage Regulator If The Overvoltage Light And Work Light Are On? Will It Be Damaged?

The overvoltage light of Static Voltage Stabilizer is on because your input voltage is too high and exceeds the input range of the voltage regulator, causing the overvoltage light of the voltage regulator to light up.

In this case, you can use a multimeter to measure the output voltage of the voltage regulator when the red light is between 250V-245V, which proves that the voltage regulator has an overvoltage alarm and no protection function.

You can measure whether the mains voltage exceeds 250V. If it exceeds, the voltage regulator is good. If it does not exceed, you need to find the voltage regulator manufacturer for repair.

As for whether the voltage regulator working light and overvoltage light are on, can it continue to be used? The answer is no, because long-term use will burn out the voltage regulator. Adjust the voltage stabilization gear to a lower level to reduce the overvoltage value. Overvoltage will cause the coil current in the transformer to rise. If it is overheated for a long time, you will feel that the voltage regulator is very hot to the touch, which is easy to burn.

The voltage regulator input is too high. The reasons are as follows:

1. The input voltage is too high, higher than the voltage regulation range.

2. The voltage stabilization sampling comparison circuit board is faulty.

3. The voltage regulator servo motor is faulty.

What you can do is to measure whether the input voltage is too high. If it is too high, the voltage regulator may not be able to stabilize the voltage.
