Automatic Voltage Regulator Output Voltage Is Unstable

What is the specific reason for the unstable output voltage of Automatic Voltage Stabilizer during use? Friends who want to know can look at the following points:

1. The input voltage of the automatic voltage regulator is stable, and the output voltage is unstable. The reasons are:

1. The load is unstable, and the change speed exceeds the response speed of the automatic voltage regulator;

2. Fault of the automatic voltage regulator.

3. The operating voltage of the general AC voltage stabilizer is between 170V and 250V. Outside this voltage range, the automatic voltage stabilizer will be protected. The "pop...pop" sound is the sound of the protection relay.

2. Solution to the unstable output voltage of the automatic voltage stabilizer:

Add a voltage regulator in front of the automatic voltage stabilizer to increase the voltage to about 1.1-1.2 times the original voltage, that is, when the voltage is the lowest (160V), the output voltage is about 180V, so that the automatic voltage stabilizer can work normally.

Note: Do not increase the voltage too high, and ensure that the output does not exceed 250V at high voltage.

After explaining the problem of unstable output voltage of the automatic voltage regulator above, let's take a look at other common sense of automatic voltage regulators:
