    Description

    The RT7670 is a High Power over Ethernet (PoE Ultra, BT) module that can deliver up to 60 Watts of output power.

    The RT7670 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 and IEEE 802.3bt Power-over-Ethernet(PoE) standard.

    The RT7670 signature and control circuit provides the PoE compatibility signature and

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

    to 60W power to the port. It has been designed to work with existing high power PSE’s from leading manufacturers.

    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.

    l Power Classification

    The RT7670 is Type 4 - Class 8 PD requesting the highest nominal amount of power from an IEEE802.3bt PSE  If the RT7670 is connected to an IEEE802.3at PSE, the PSE will recognise the initial Class 4 pulse from the as a Type 2 PD and provide ~25W.


    l PD Signature

    The RT7670 input complies with the IEEE802.3af specification. When the inputs are connected to a Power Sourcing Equipment (PSE), they will automatically present a Powered Device (PD) signature to the PSE (when requested). The equipment will then recognise that a PD is connected to that line and supply power.

    The J1  S1 S2 pins must be connected together when used with a Phihong POE80U or POE60U PSE.



    l Operating Temperature Range

    It is important to remember that RT7670 is a power supply, and as such careful consideration should be taken over the mechanical design of the host product, with provision for heat sinking and/or forced air cooling.

    At full power the RT7670 will generate heat. The device has been designed to be used with heatsink plate or thermally connected to the chassis of the host equipment, or cooled with forced air.


    l About cooling

    RT7670  if work At full power 60W putout ,need forced air or metal heatsink/ enclosure

    1. Air flow: Min 2.2 CFM
