4.When the switch is turned on, why AVR can’t start the work?

Possible reasons:

1.Improper connection, there might be loose contact from the AC mains and or from the AVR to the appliances;
2. overloading, the power capacity of the connected appliance exceed the stabilizer maximum output power. Usually in this case, the fuse will blow up or the circuit breaker will trip off;
3. Different frequency between the AVR output frequency and the frequency of the electrical appliance.
1. make sure that the utility power is properly connected to the AVR and the AVR to household appliances;
2.ensure that AVR is not overloaded.
3.make sure the AVR output and loaded appliances in the same frequency range.

5.When you switch on the AVR, why the LED lights display ”unusual” ?

Possible Reasons:
1. high or low input voltage exceeds the AVR input voltage range;
2. high temperature protection;
3. circuit failure.

1. wait until the input voltage return back to the AVR adjustment range;
2. switch off the AVR and let it cool down;
3. bring to the service center for repair.

6.Why does the AVR immediately trip off when it is switch on?
The loading capacity must exceed the fuse amperage or circuit breakeramperage!
In this case, you need to reduce the load, or use a larger capacity of the AVR to power the loaded appliance.
