PoE Switches

We provide a wide range of PoE/PoE+/PoE++ switches with up to 90 W output per port to deliver high-speed data transmission while powering high-power devices over long distances. With an industrial-grade design, our PoE switches provide surge protection of 4 kV per LAN port. Additionally, Smart PoE management features simplify PoE network deployment and maintenance.
