    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: Troubleshooting switching power supply

    1. There is voltage output, but the voltage remains too high.
      This malfunction is mainly caused by regulated sampling circuit and regulated control circuit. DC output, sampling resistance, error sampling amplifier (such as TL431), opt coupler, and control circuit of power supply form up a closed control circuit. Any problem at the circuit will lead to over tension of the output voltage.
    2. Poor load capacity
      Poor load capacity is a common malfunction. It is often seen at traditional power supplies or those which work for long hours. It is caused by aging components, unstable switch tube, or poor cooling condition. Users shall check and confirm the status of regulated diode, rectifier diode and HV smoothing capacitor etc.
