The EPW15 Power over Ethernet Plus (PoE+) Transformer is designed for high-power Ethernet applications requiring stable power delivery and reliable data transmission. Built with a high-performance EPW15 ferrite core and precision winding technology, it ensures efficient energy transfer, excellent signal integrity, and strong EMI suppression.
This transformer is optimized for PoE+ (IEEE 802.3at) systems, supporting higher power levels compared to standard PoE solutions. It is widely used in PoE switches, IP surveillance cameras, wireless access points, VoIP devices, and industrial Ethernet equipment.
Its compact structure allows easy integration into high-density PCB designs while maintaining long-term electrical stability and thermal reliability. Custom designs are available for different network power requirements.
