Introduction

This PoE (Power over Ethernet) module is a legacy Cat 5 and Cat 6 twisted-pair Ethernet power module based on the IEEE 802.3at PoE standard, designed to extract power from a PSE through standard Cat 5 and Cat 6 Ethernet cables. The module input complies with IEEE 802.3at signature detection and classification standards, pre-configured as a Type 2, Class 4 device, allowing the module to draw Class 4 power from a PSE with a rated output voltage of 24V. The high-efficiency DC/DC converter achieves approximately 87% efficiency, operates over a wide input voltage range, and delivers low-ripple, low-noise output. The DC/DC converter also features built-in output overload and short-circuit protection, and provides a 1500Vdc (input/output) isolation barrier.
