This device lets you use any 48V PoE source (including Passive PoE, Telecom PoE, 802.3af and 802.3at) to power RouterBOARD devices. Simply plug any 48V PoE powered ethernet cable into one port, and any 8-30V capable RouterBOARD device into the other. This device is able to provide high power output - up to 24W (up to 1A at 24V). You can power it with virtually any 42-57V PoE solutions available on market today (Passive, Telecom, 802.3af and 802.3at PoE plus supported).
The device is a rugged metallic design with high capacity components and integrated heat sink design. The case also has mounting holes so you can attach it to a wall. Ethernet shield pins are inside the Ethernet connectors so that shielded ethernet can be used to ground either at the converter itself or at the devices at both ends.
