-
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. 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
