-
1. 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.
-
2. 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.
-
3. Does the voltage regulator frequently lose power?
Possible reasons include improper adjustment of overvoltage value on control circuit board. The solution is to readjust or repair.
-
4. 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.
