-
1. 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.
-
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. DC switching regulator overload?
If the load exceeds the voltage regulator's tolerance, the voltage regulator will burn out.
