„GB PoE+-Ethernet-USB“ adapter for industrial use with an EMC perspective
Overview
| Topology | LAN / POE |
| Output 1 | 57 V |
| IC revision | a |
Description
The " GB PoE+ Ethernet USB adapter" is based on the reference design of a 1 Gbit/s Ethernet USB adapter without PoE function, which was described in detail in RD016. The " GB PoE+ Ethernet USB Adapter" offers three interfaces, a USB Type-C (USB 3.1), an RJ45 1 Gbit/s Ethernet interface with integrated PoE function, and a connector for a DC/DC converter with an adjustable output voltage of 6 to 18 V and a maximum output power of 25 W. The board is designed to get users acquainted with PoE technology.
