NMPD Series of compact power extraction modules from C&D Technologies Inc., Power Electronics Div., Mansfield, MA, are powered device (PD) modules for Power over Ethernet (PoE) applications. The PD interfaces feature onboard DC/DC conversion and provide a full IEEE 802.3af-compliant data and power interface to an Ethernet line, including short-circuit protection. Operating with a max. output power rating of 10 W, modules extract power from a CAT5 twisted-pair Ethernet cable when sourced by IEEE 802.3af-compliant power-sourcing equipment. Applications include PoE designs for security equipment, public address systems, remote environmental monitoring, telemetry, and industrial control.
