    PROTECTION Short circuit   The power supply can resume normal operation when the short circuit is removed during power supply.
    Overload 105%-200% rated output power
    Protection type:Hiccup mode,recovers automatically after fault condition is removed
    Over current After the over current fault is removed, the power supply will automatically resume normal operation.
    Over voltage   When the output voltage exceeds the rated voltage, the power supply will be protected and normal operation can be resumed after the fault is removed.

    Safety standards  Design by IEC60950 standard
    NOTE All parameters NOT specially mentioned are measured at 240VAC input,rated load and 25℃ of ambient temperature.
    Ripple & noise are measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1uf &47uf parallel  capacitor.
    Tolerance: includes set up tolerance. Line regulation and load regulation.
    Length of set up time is measured at first cold start .Turning ON/OFF the power supply may lead to increase of the set up time.
