Ask a Question
  • Can the WT-GPOE-4B be used with 48V dc

    Yes, this injector can be used with a 48VDC power supply. The GPOE-4B will send power on Mode B (+4,5, -7,8). Please reference our Mode A vs. Mode B blog to learn more about the difference in modes. 

  • I am hoping to run some Ubiquiti 24v gear out of an industrial control box with an existing 24vdc power system. Is the 2.1mm connector a 2.1mm x 5.5mm barrel? Is there a DIN rail mount for this?

    Yes, the female DC connector is 2.1mm x 5.5mm. We do offer a DIN rail mount in the beta room for some of our products, but this injector is wall-mountable.
