-
1. The voltage stabilizer cannot start the manual control mode without voltage adjustment function?
Possible reasons include limit switch failure, boost and down pressure button failure, poor contact of the voltage stabilizer motor power supply, etc. The solution includes replacing the limit switch, checking the connection line, replacing the button, connecting the voltage stabilizer power line, etc.
-
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.
