What is Power over Ethernet?
Power over Ethernet ( PoE ) is also called PoE power supply , which is a technology that can transmit power and data to the device through twisted pair wires in Ethernet.
- With this technology,
- PSE provides 44 ~ 57V voltage, about 350
- The PSE terminal provides a voltage of 50 ~ 57V and a DC power supply of about 600mA. Each port must provide at least 30W of power. After 100 meters of CAT-5 cable, the PD terminal must receive at least 25.5 W.
