    3. Alarm



    Alarm signal
    ItemsYes / noTechnical indicationNotes
    Power down alarm signalYes

    When normal input, output low impedance;

    When the power off, output high impedance

    AC input fails, output +52V, in the case of full load, alarm signal is up to + 2.2 V (test need to add pull resistance); when +52V drop to +38 V, time interval shall not be less than 1 ms
    Normal input LED displayYesUsing indicator light(red): red light is on, input is normal
    Normal output LED displayYesUsing indicator light(green): green light is on, output normal 52V
    Output on/off controlYesOutput switch controller controls internal power supply protection circuit signal electric potential by rocker switch on the panel to achieve output power off and on.

    Note:


    1. The power indicator light is required to install on the PCB board ( in the same side of the input and output socket), the red light on the input, the green light on the output.

    2. Alarm port circuit requirements: when input power is normal, optocoupler conduction (saturation), alarm port output low impedance . When input power is down, Optocoupler cutoff, IN OK port output high impedance, and the driving current of alarm port need reach 10mA.
