This PoE injector is a 30W single port solution for remote powering the Kerlink's Wirnet range by AC power supply. One RJ45 port is for Ethernet input, the other is for Ethernet output + Power.Two LEDs have diagnostic functions. One “POWER” is for Input Power (green), the other “ACTIVE” is for Output Power (green up to 15,4W and blue above).This PoE injector provides 55Vdc, 0.55A with input AC voltage (up to 30W) over the full temperature range -40°C to 65°C. Automatic Detection and Protection of nonstandard Ethernet terminals implemented.
