Tycon Power's POE-INJ-S PoE Injectors
POE-INJ-S PoE Injectors inject dc power to a Cat. 5 cable to power remote equipment using Power over Ethernet. There is an LED version with one LED that indicates power is being supplied to the inserter. The other LED indicates when a device is plugged in at the far end of the Cat. 5 cable and that device is drawing current.
