Tips: Why the output voltage of switching power supply is too low?
Except regulated control circuit, the following aspects may also cause undervoltage output of SMPS power supply.
1. Switching power supply load presents short circuit (particularly short circuit or performance of DC/DC convertor). In case of the foresaid condition, users need to clear load of the switching power supply to check working status of the power supply and the load circuit. If voltage output appears normal after cutting off load circuit, which means the condition is caused by overload. If voltage output remains abnormal, that means there is problem with the switching power supply.
2. Failures of rectifier diode and smoothing capacitor at the output terminal can be confirmed by substitution.
3. Deteriorating performance of switch tube will result in breakover failure which would increase internal resistance of the SMPS power supply and lower its load capacity.
12V DC switching power supply (SMPS) works at rated power of 200W and rated current 16.5A with low price and high quality. Great SMPS power supply with short circuit, overload and overvoltage protections, widely used at office devices, household appliance and industrial equipment.
