3. Alarm
| Alarm signal | |||
| Items | Yes / no | Technical indication | Notes |
| Power down alarm signal | Yes | 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 display | Yes | Using indicator light(red): red light is on, input is normal | |
| Normal output LED display | Yes | Using indicator light(green): green light is on, output normal 52V | |
| Output on/off control | Yes | Output 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.
