Embedded PoE/PoE+ Modules - PSE & PD Modules
 

1. General
Power over Ethernet is a revolution solution for Ethernet communication. PoE can provide power and Ethernet communication signal simultaneously from local side to remote device via a single Cat. 5 cable, because all of electronics devices need power when they are operated.

The PoE link needs one Power Sourcing Equipment (PSE) and one Powered Device (PD) to implement it. So far, IEEE802.3af-2003 is the PoE standard for normal power application and the IEEE802.3at-2009 is the advanced version for high power PoE (PoE+) application..

2. Befact Technologies PoE Embedded Solutions (Modules)
Befact Technologies provides total solutions of embedded PoE modules, including normal and high power applications. And all of Befact PoE products are IEEE802.3af/at compliant. For high power solution, it is not only can support high power mode but also is backward compatible to normal power application.

(1)  PD Embedded Modules (Isolated mode)
A. High Power (PoE+ 25.5W, IEEE802.3at compliant) PD – AHPD-12 (12V/2.125A, 92%)
B. Normal Power PD - TPD-12 (12V/12W, 89%), TPD-50 (5V/12W), TPD-33 (3.3V/12W); SPD-12 (12V/12W, 89%), SPD-50 (5.1V/12W); PDI-12 (12V/12W, 92%), PDI-50 (5V/12W).

(2) PSE Embedded Modules
A. High Power (PoE+) Quad Port PSE – PSE-HQD (maximum current - 650mA/port).
B. Normal Power Quad Port PSE – PSE-QD (maximum current – 450mA/port).

3. Implement Single Voltage Power Supply PoE Enabled Ethernet Switch by PSE-QD, PSE-HQD, TPD and THPD Module
The PoE enabled Ethernet switch needs two primary power sources, one is for PSE module (typical 48Vdc) and another one is low voltage power source (example - 12Vdc / 5Vdc) for Ethernet switch, CPU, Flash memory, RAM,… and so on. So, the power supply has to source two different and isolated output voltages; alternative solution is an isolated DC/DC power module is equipped to be as the low voltage power source for Ethernet switch, CPU, Flash memory, RAM,… and so on.

Now, Befact Technologies provides an easy, quick and low threshold solution to implement PoE enabled switch. The SPD, TPD , PDI and AHPD module can be as an isolated primary low voltage DC/DC power source for CPU, Flash memory, RAM and peripheral circuits and share the same primary power source (typical 48Vdc) with PSE-QD or PSE-HQD module.

4. Implement PoE Enabled Remote Device by TPD, SPD, PDI and AHPD Module - Example PoE Enabled IP CAM

5. Implement Double Power PoE Link by Befact PoE Embedded Solution
A. Double Normal Power PoE Link (Example in One Port, Up to 40W Output Power)

B. Double High Power (PoE+) PoE Link (Example in One Port, Up to 60W Output Power)

6. Implement Double Power in Gigabit Ethernet Application
A. Double Normal Power PoE Link (Example in One Port, Up to 40W Output Power)

B. Double High Power (PoE+) PoE Link (Example in One Port, Up to 60W Output Power)
