Introduction

The module is designed to extract power from traditional class 5 Ethernet cable twisted pair, and meets IEEE 802.3at power Ethernet (POE) standard. Based on the IEEE 802.3at standard, this paper establishes information connection about the connection status, device type, power consumption level of the receiving device PD, and then applies 25W 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.

Features

• Compliance with IEEE802.3at standard.
• 39V~57V wide operating voltage range.
• Maximum output power up to 25W; Rated output: 12V/2A.
• The output ripple is less than 150 mV.
• Conversion efficiency can be as high as 88% (input: 48V output 12V@2A).
• With overcurrent, short circuit, under voltage, surge and other excellent reliability and circuit protection.
• PCBA standard size: 53.4mm14mm16mm
• Input/Output: isolate 1500Vdc.
• High reliability: The design meets the 5 million hour average failure interval.

Applications

• Video and VoIP Phone
• RFID Reader
• Multiband Access Point
• Surveillance camera
