    PROTRCTION

    Short circuit

    The power supply can resume normal operation when the short circuit is removed during power supply.

    Overload

    105%-150% 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 temperature

    Ambient Temperature 70℃ ± 10%

    Protection mode; the product is hiccup state, protect the product from damage, when the fault is ruled out, the power supply is normal.

    NOTE

    All parameters NOT specially mentioned are measured at 230VAC 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.

    1. Adjustable photo electron driver; one dimmer can drive multiple power supplies;and the numbers aredecided by the dimmer maximum load capacity. The positive and negative of dimmer should be connected topositive and negative of the power supply’ s dimming.Terminals,Regulating the dimmer will produce a kindof 0-10V signal to power supply, then changing the luminous flux of the lamp.
    2.Regulations Dimming operation Tandem triac dimmer before input terminals AC,then adjust the outputconstant current value.
    Notice:the output of the 0-10V adjustable photo electron driver that dimming interface of the power supplysupply connected should be a stable 0-10V DC voltage.
