APPLICATION NOTES
Power Over Ethernet (PoE) is a technology for wired Ethernet, the most widely installed local area network technology in use today. PoE allows the
electrical power necessary for the operation of each end-device to be carried by data cables along with the data, rather than by separate power
cords. Thus, it minimizes the number of wires used to install the network, resulting in lower cost, less downtime, easier maintenance and greater
installation flexibility.
The IEEE standard governing PoE is IEEE802.3af. Compliance with this standard ensures inter-operability between devices.
The PEM1200 series modules offering a modular solution, incorporating full IEEE802.3af compatibility signature to the PSE and isolated on-board
DC/DC converter. The PEM1200 series are ideal modular system blocks allowing manufacturers of Ethernet equipment to “PoE enable” their
equipment with minimal effort and cost. The PEM1200 modules series offer simple and quicker product development, maximising return on
investment.
PEM1200 can be powered using a user designed power supply which has adequate thermal and over-current protection. It is strongly
recommended that only IEEE802.3af compliant power supply equipment be used to prevent damage to the module, which lacks output stage
thermal protection .
ESD Protection: It is required that the system designer must provide ESD protection such as an SMAJ58A (uni-directional) or SMAJ58CA (bi-
directional) TVS diode at the PEM1200 input(s) to prevent damage from over-voltage surges and for system EMC compliance.
