-
1. The voltage stabilizer has no automatic adjustment function?
Possible reasons include sampling transformer damage, control circuit board damage, etc. The solution includes repairing or replacing damaged parts.
-
2. The output voltage of the voltage stabilizer deviates from the regulated value?
Possible reasons include no response to the adjustment potentiometer or a broken circuit board. The solution includes replacing the circuit board or potentiometer.
-
3. The output voltage of the voltage stabilizer oscillates?
Possible reasons include too high output voltage accuracy. The solution includes adjusting the potentiometer and adjusting the voltage value appropriately.
-
4. No output voltage from the voltage regulator?
Possible reasons include open circuit of normally closed contact of stop button, broken contact of voltage regulator button, etc. The solution is to replace damaged parts.
