The PS4820-POE-1 is a Power-over-Ethernet (PoE) Injector/Midspan with integral 48 Volt, 20 Watt power supply. It provides DC power for one PoE-equipped device by "Injecting" DC power through the CAT5 ethernet cable. It is compatible with AP's and other equipment supporting the IEEE standard PoE pinout (Pins 4&5 Power + / Pins 7&8 Power -).
Since the PS4820-POE-1 is completely self-contained, a separate power supply and injector is not required. The PS4820-POE-1 features an impact resistant polycarbonate enclosure and includes a 3-prong detachable power cord.
