4-Port Gigabit Mode A PoE Injector without Power Supply


Simplify installations with a multi-port midspan injector. Power up to four IP cameras, desktop phones, WiFi access points, or other low voltage devices through a network data cable using this Power over Ethernet (PoE) injector. A Passive PoE injector always delivers the same voltage as its power source. Kit this injector with a 48v or 56v power supply to provide direct voltage to your IEEE 802.3af/at device.

Compatible with IEEE 802.3af with Mode A Negotiation. This midspan meets the IEEE standard negotiation using pins 1,2 / 3,6 to deliver PoE power to your device.

Ask a Question
  • looking for a 4 port poe solution for my ip cameras. fd8381-ev. recommendations?

    This Vivotek camera is 802.3 AT POE compatible and consumes a maximum of 22 watts per device. Our WT-AT-4-56v120w or WT-AT-8-56v120w are 2 802.3 AT injectors (power supply included) and will work great with this Vivotek Camera.

  • I don't want to fry my PoE cameras with 48v, do they regulate voltage on the far end?

    PoE cameras accept 44-56 volts and step it down internally to the chip voltages of 5 volts or less. This reduces loss in the Ethernet cable.

  • Each device needs it\'s own data line? Why is that?

    A PoE injector (like this one) adds power but data only passes through. A PoE switch (like the WS-GPOES-8-7) will work with a single data input.
