Ask a Question
  • Hi, Do you you have any MODE B Passive POE injectors? (multiport if possible to power several devices)

    Yes, we offer the WT-GPOE-4B, the WT-GPOE-8B, and various others which offer both Mode B and Mode A. Please contact our expert technical support at 512-479-0317 for your specific needs. 

  • Can I use this in a configuration with one incoming LAN to split to 2 powered outgoing 802.3af cat 5 cables?

    This product is a passive midspan PoE injector. It will require one line of data into each LAN port to provide data on the corresponding PoE out port. If you are looking to only use one data line in and get PoE out of all ports, please see our PoE switches. As always, feel free to contact our tech support at 512-479-0317 for your specific run. 

  • I have the WT-GPOE-4-48V48W. On the product specs here, it says a max of 1.25A per port, but on the device itself, it says 650mA per port. Which is correct? Thanks.

    Thank you for bringing this to our attention. The 1.25A is the maximum power supply output. The limit per port is 0.65A / port.

  • ¿este dispositivo puede alimentar a 4 equipos ubiquiti PBE-M5-400 sin problemas?

    No, para el pago de Ubiquity PBE M5-400 o la versión WT-GPOE-4-B-24V30W de 4 Puertos, esto alimentará sus 4 unidades.

  • I have a WT-GPOE-4-48v48w that has stopped working...no active LED on power supply or injector. Is there a fuse inside or something else that might have tripped?

    This injector does have fuses inside, and each port has a fuse limit of .65A. Our support team will send you an email to find out more about your application. 

  • I have your POE injector WT-GPOE-4-48V48W at home. I need to be able to connect two non-POE cameras. Both are 5V 1.3A and use a 2.1mmx5.5mm plug. What should I order? At work I am using a Juniper EX2200-C POE+ and want to be able to run a Raspberry Pi 3B+. What POE splitter would you recommend for my use at work?

    For the 5v 1.3amp devices you will need WT-AF-5V10W with our 1.35 to 2.1mm RA Adapters. For the Raspberry Pi, you can use our WT-AF-5V5W with your PoE + Switch.
