    Description

    The 万博全站官网-万博全站手机下载 series of modules are designed to extract power from a conventional

    twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3af and IEEE 802.3at Power-over-Ethernet(PoE) standard.

    The 万博全站官网-万博全站手机下载 signature and control circuit provides the PoE compatibility signature and

    power classification required by the Power Sourcing Equipment (PSE) before applying up

    to 30W power to the port.

    The DC/DC converter operates over a wide input voltage range and provides a regulated

    output. The DC/DC converter also has built-in short-circuit output protection.

    VA2

    TX Input (2). This input pin is used in conjunction with VA1 and

    connects to the centre tap of the transformer connected to pins 3

    & 6 of the RJ45 connector (TX) - it is not polarity sensitive.

    3

    VB1

    Direct Input (1). This input pin is used in conjunction with VB2 and connects to pin 4 & 5 of the RJ45 connector - it is not polarity

    sensitive.

    4

    VB2

    Direct Input (2). This input pin is used in conjunction with VB1 and connects to pin 7 & 8 of the RJ45 connector - it is not polarity

    sensitive.
