-
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. Decrease in voltage regulator load capacity?
Possible reasons include defective brushes, poor contact between brushes and voltage regulator coil, etc. The solution includes replacing brushes, adjusting brush spring pressure and brush position, etc.
-
4. DC switching regulator overload?
If the load exceeds the voltage regulator's tolerance, the voltage regulator will burn out.
