The MikroTik RBPOE is a passive PoE Injector, equipped with a Fast Ethernet port (10/100 Mb/s). It is used for powering devices via Ethernet cable. The product complements MikroTik's high-quality power supplies, which are characterized by innovative solutions. It supports voltage in the range of 10 - 28 V DC and uses passive PoE. When using a RouterBOARD that supports 10-28V PoE, the input must have a voltage of at least 18V to cover cable losses.
