    1. General Details

      The PEM1200 series of PoE modules are designed to extract power from CAT5e or higher Ethernet cable, conforming to the IEEE 802.3af Power over Ethernet (PoE) standard. The PEM1200 series is identical to the PEM1300 series, except the PEM1200 series do not have on-board bridge rectifier diodes.

      The PEM1200 provides 1500 V DC isolation between input and output. It features adjustable output voltage and programmable IEEE 802.3af power classification enabling users to design their products for the growing “green power” movement.

      The PEM1200 is a full featured yet cost effective solution useful in general purpose segments including the IP network camera, VoIP phone, access control, RFID, wireless access points, and office/building automation segments.

      Input
      Input Voltage
      36V to 57V DC (for higher power operation an input voltage of 51V or higher is recommended) Extracts power from either data pair (pins 1,2,3,6) or spare pair (pin 4,5,7,8) or both pairs
      Input Current
      600mA maximum continuous as per draft IEEE 802.3at
      PD Detection
      Presents IEEE802.3af PD signature and Class 0 classification to PSE on any one pair
      Ports
      RJ45 shielded connector for PoE Input
      Output
      Output Voltage (±3%)
      12V           13.5V           15V            18V            21V            24V
