Power over Ethernet Transformer EP13

The EP13 Power over Ethernet (PoE) transformer is an industrial-grade surface-mount (SMT) magnetic component, purpose-built for PoE-powered devices (PDs). Boasting improved power-handling capabilities over the EP7 and EP10 models, it is optimized for high-power applications in modern networked systems.

This flyback transformer delivers robust performance with a 36–57 V input range, 200–500 kHz switching frequency, and reliable operation from -40 °C to +125 °C. It also provides 1.5 kVAC (1-minute) isolation between primary and secondary circuits, with multiple output power and voltage configurations to suit diverse design requirements.

Widely deployed in PoE-enabled equipment, the EP13 is an ideal choice for IP telephones, wireless LAN access points, access control terminals, and surveillance cameras, ensuring stable power delivery in professional networking environments.
