The HyperLink BT-CAT5-P1-4848 Single-Port CAT-5 Midspan/Injector kit (also known as PoE Passive Splitter) is a commercial grade Power-over-Ethernet device that provides DC power for one PoE-equipped device. It is compatible with AP’s and other equipment supporting the IEEE standard PoE pinout (Pins 4&5 Power + / Pins 7&8 Power -).Power-over-Ethernet eliminates the need for an AC outlet at each AP location. Only a single Ethernet cable is run to each AP instead of separate power and data cables. The injector is typically installed near the Ethernet hub.This unit can be used as either an "Injector" or as a "Tap". When used as an injector the device sends DC power through the Ethernet cable to a remote PoE device. When used as a "Tap" this unit taps the injected DC power from the Ethernet cable for use by certain non-PoE devices.Integral Surge ProtectionThe integral lightning and surge protection individually protects the 4 data lines as well as protection for the power lines. High speed devices clamp any voltage, positive or negative on the wires. The limits are +/- 15 volts on pins, 1, 2, 3, 6 and +/- 58 volts on pins, 4, 5, 7 and 8.The BT-CAT5-P1-4848 features shielded RJ45 jacks. This along with the BT-CAT5-P1's metal housing helps reduce the effects of EMI interference. A ground lug and terminal is provided directly on the injector housing providing superior grounding. The cast aluminum housing includes integral mounting feet for ease of installation.This kit includes the injector/tap and a 48VDC @ 48W power supply (PS4848-25R).This unit is also available individually or in the following kits:Injector only - BT-CAT5-P1 With 48VDC @ 70 Watt Power Supply - BT-CAT5-P1-4870 With 56VDC @ 117.6 Watt Power Supply - BT-CAT5-P1-56118
