What should I do if the AVR(Automatic Voltage Regulator) cannot stabilize the output voltage?

When the Automatic Voltage Regulator cannot stabilize the output voltage, you can try the following methods to solve the problem:

Check the input voltage: The inability of the AVR to stabilize the output voltage may be caused by fluctuations in the input voltage. Therefore, it is necessary to ensure that the input voltage received by the AVR is stable to ensure the stability of the output voltage.

• Check the load: Check whether the load of the equipment connected to the AVR is reasonable. Excessive load will affect the stability of the AVR.
• Check the connection: Check whether the connection between the AVR and the power supply and load is good, and make sure the connection is firm and reliable.
• Check the circuit: Check whether the internal circuit of the automatic voltage regulator is normal. There may be component aging or failure causing the output voltage to be unstable.
• Restart AVR: Try to restart AVR. Sometimes a simple restart can solve some temporary problems.
• Check the manual: Check the AVR user manual to understand the fault codes and solutions, and follow the instructions in the manual to troubleshoot.

If the above methods cannot solve the problem, it is recommended to contact the AVR manufacturer or professional maintenance personnel for further diagnosis and repair.
