Description:

PoE_v.1.2 module is an Ethernet PoE splitter for 10/100/1000Mbps LAN networks which supports such standarts as IEEE 802.3bt with PoE high-power PD interface with automatic MPS & autoclass recognition.

Module supports Power Levels for up to Type-4 90W and Type-3 60W Operation , power modes higher than 25W must be implemented together with appropriate cooling solutions / additional heatsink.

The Automatic MPS function of the module enables applications requiring very low power standby modes. The PoE_v1.2 module automatically generates the necessary pulsed current to maintain the PSE power.

The PoE_v1.2 module also implements a delay function to allow the remote PSE to complete its inrush phase before releasing the Power Good (PG) output. This ensures that the IEEE802.3bt (draft) startup requirements are met. The Auto class enable input also allows advanced system power optimization modes compliant with IEEE802.3bt (draft) standard.
