Overview

IM141020002pic3.jpg

In the PoE scheme, two different types of devices are involved: Power Sourcing Equipment (PSE) and Powered Devices (PD). Compatible with IEEE802.3af standard, SPD8001 is an isolation type PD module for PoE system so that the electric energy can pass from PSE to SPD8001 module though Ethernet cable.

With multiple protecting functions such as over current, input under voltage and over temperature, this module provides a stable and reliable PoE solution for you.
