    Note 1. All parameters NOT specially mentioned are measured at 230V AC input, rated load and 25°C of ambient temperature.
    2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
    3. Tolerance includes set up tolerance, line regulation and load regulation.
    4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.

    Tips: Switching power supply output voltage is too low, how to do?
    Except regulated control circuit, the following aspects may also cause undervoltage output:

    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 power supply and lower its load capacity.
