1. The voltage stabilizer cannot start?
Possible reasons include the wrong phase sequence of the input power line, the air switch in the machine is not turned on or damaged. The solution is to swap any two power connections or check whether the power line is normal, close the switch or replace the switch.
-
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. DC switching regulator overload?
If the load exceeds the voltage regulator's tolerance, the voltage regulator will burn out.
-
4. DC switching regulator overheating?
If the heat dissipation is not good or the ambient temperature is too high, the voltage regulator temperature will be too high, causing failure
