    1. General Details

      The PEM3200 is globally one of the smallest size, full power IEEE802.3at and IEEE802.3af compliant Power Over Ethernet (PoE) Powered Device (PD) extraction module delivering up to 30 watts peak power, when sourced from a competent power IEEE 802.3at Power Sourcing Equipment (PSE), using twisted pair CAT5 or higher Ethernet cable. It offers fixed POE Class 4 and provides Two Event Physical Layer (Layer 1) classification, as per IEEE802.3at and supports layer 2 classification via an “AT Detect” pin. The module also supports Type 1 and Type 2 PD operation of the IEEE 802.3bt.

      The PEM3200 output ripple is controlled within IEEE specifications. For improved EMI performance, the PEM3200 is featured with in-built frequency dithering and a dedicated pin for adjusting the switching frequency for additional tuning for targeted EMI filtration. PEM3200 supports external Auxiliary DC power, and enables Remote Shut Down to keep POE supply on standby mode.

      The PEM3200 is a low cost solution with a high efficiency DC-DC converter with 1500V safety isolation, in-built under-voltage, over-voltage, output over-load and short-circuit protection. The PEM3200 series require minimal external components and provide a quick, easy, and cost effective method for Ethernet equipment manufacturers to “PoE enable” their equipment.

      PEM3200 is ideal for POE application for IP & PTZ cameras, gaming instruments, audio & video interfaces, security and access control devices, door monitoring, sensors, environment control devices, routers, and network access points.
