Ag59FE PoE Configurable PD Controller Module

The Silvertel Ag59FE module is a power-over-Ethernet-powered device (PD) controller module that can be paired with a DC/DC converter to provide a complete PoE solution.

Designed to extract power from a conventional twisted pair Category 5 Ethernet cable, the Ag59FE complies with the IEEE802.3 specifications, including full compatibility with the IEEE802.3af, IEEE802.3at, and IEEE802.3bt amendments, and provides the required signature and control circuitry within.

The Ag59FE can be configured as a Type 1, 2, 3, or 4, Class 0-8 PD device, requesting up to 90 W of power from the PSE.

The Ag59FE does not require a load for operation; however, PoE does have a maintain power signature (MPS) requirement as stipulated in the IEEE802.3 specification to ensure that power is not supplied to an unconnected port. To prevent any device from being disconnected, the Ag59FE can apply a pulsed load to the Ethernet link to satisfy the MPS requirement while minimizing power consumption. If the PSE has indicated it supports the low-power MPS introduced in the IEEE802.3bt, amendment, the Ag59FE will automatically change to the low-power profile for the pulsed load to further reduce power consumption.

Designed and manufactured in the UK to the ISO9001 standard, this PoE module, when used in conjunction with an isolated DC/DC converter, constant current circuit, or enclosure, creates a fully compliant PD solution, providing a DC voltage to the connected peripheral device.
