3.describe

The module is designed to extract power from conventional Class 5 Ethernet cable twisted pairs and meets the IEEE 802.3af Power-Ethernet (PoE) standard.At the same time, the module allows the power supply category to select "Intermediate Overlap" and "End Overlap" power supply without distinguishing polarity.

Based on the IEEE 802.3af standard, this paper establishes information connection about the connection status, device type, power consumption level of the receiving device PD, and then applies power supply to port compatible devices based on PSE to power the PD through ethernet.

This module DC/DC converter works in a wide input voltage range and low ripple low noise output.The DC/DC converter also has built-in output overload, output short circuit and overtemperature protection, and provides a 1500Vdc (input/output) electrical isolation.

1: Typical number is 25 C, nominal voltage is 48V, for auxiliary design only.

2: Output ripple and noise can be reduced by an external filter, see the application instructions.

3: If operated under the specified minimum load, the module emits audible noise and may cause PSE malfunction.
