Power over Ethernet Plus Transformer EPW15

Power over Ethernet Plus Transformer EPW15

As a key element in isolated DC-DC conversion for Power over Ethernet Plus, the EPW15 transformer enables compact and efficient power delivery over data lines. Its design supports forward or flyback topologies at switching frequencies up to 400 kHz, meeting the rigorous 30W power objectives set by the IEEE802.3at standard.

This makes it an ideal, ready-to-integrate solution for powering a wide array of PoE+ Powered Devices (PDs), including equipment in industrial automation and intelligent lighting networks, where combining data and power on a single Ethernet cable simplifies installation and reduces costs.
