EPE-5818Gaf is a single-port power injector for Power-over-Ethernet (PoE) applications for use with gigabit systems. Unlike existing power injectors, the EPE-5818Gaf is not limited to working only on 10baseT or 100baseT systems, but is compatible with systems up to 1000 Mbps. It can easily extend the wired connection distance through the Ethernet cable which avoids the long power line which might bring dangerous and incident. EPE-5818Gaf offers power supply up to 48V/375mA with Ethernet cable. 4 Pairs are with data transmission; pin # 4,5 and 7,8 with power enabled to device via center tap (center tap is a connection made to a point half way along a winding of a Transformer). The EPE-5818Gaf PoE generates safe power over category 6e. By sending 48V, Ethernet terminals which need more power such as wireless LAN high power device, IP media center, and web camera are powered remotely.It is especially design for outdoor networking facility and low port density installations.
