L-Com BT-CAT5-P1J-4848 Single-Port Passive PoE Injector/Picker with 48VDC @ 48 Watt Power Supply



  • The BT-CAT5-P1J-4848 Single-Port CAT5 PoE Midspan/Injector (also known as PoE Passive Splitter or Tap) is a commercial grade Power-over-Ethernet device that supplies power for a 10/100 Base-T Power-over-Ethernet, PoE equipped network device. It is compatible with a Power Device (PD) that support the IEEE 802.3af standard PoE power feed using Mode B (Pins 4/5 and 7/8). Additionally, the unit supports both positive and negative DC as well as AC power up to 55 volts. Only a single Ethernet cable is run to each Network Appliance instead of separate power and data cables. Power-over-Ethernet eliminates the need for an AC outlet to be installed.

  • The BT-CAT5-P1J features integral surge protection for the data lines and power feeds. The unit eliminates the need for an external surge protector. The unit provides protection for both common and differential mode surges. High-speed semiconductors clamp any voltage, positive or negative on the wires. The limits are +/- 58 volts on the four cable pairs. The design utilizes Thyristor diode technology which has superior power handling capability compared to TVS or Avalanche diode based designs. The BT-CAT5-P1J can also be used as a standalone lightning surge protector.

  • A ground lug and terminal is located directly on the injector housing providing superior grounding. The cast aluminum housing includes integral mounting feet for ease of installation.

  • This kit includes the protector/injector and a 48VDC @ 48W power supply (PS4848-25R).
