Eaton PoE transformers in flyback and forward designs for PoE applications Eaton Power-over-Ethernet high voltage transformers
■Eaton’s Power-over-Ethernet transformers (PoE) are suitable for a wide range of ethernet power devices using IEEE802.3 ethernet protocols. Eaton’s PoE transformers support various PoE controllers across many power devices ranging from 3 W to 156 W. Eaton’s PoE comes in 6 standard transformer sizes (EP10, EP13, EFD15, EFD20, EFD25, EFD30) and in both flyback and forward topologies. Flyback designs are often used as energy storage while the forward designs provide energy transfer mostly for high power outputs, typically 50 watts and above.
■Applications for the PoE transformers include lighting, remote cameras, industrial automation, security systems, Voice over Internet Protocol (VoIP), network access points, chargers, network routers, bluetooth, and network repeaters. They perform reliably in high operating temperatures ranging from - 40° C to + 125° C and up to 1500 V isolation voltage.
●Features and benefits
■Flexible/standard footprint options
■Design flexibility across sizes and electrical performances covering from 3 W to 156 W
■Full PoE transformer line covering IEEE Type 1 (802.3af), Type 2 (802.3at), Type 3 (802.3bt), Type 4 (802.3bt)
■Offered in two popular topologies: flyback and forward designs
■1500 Vac isolation between primary and secondary
■High operating temperature to - 40° C to + 125° C
■Low leakage inductance for low-loss energy storage
