-
1. 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.
-
2. 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.
-
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
