Description:
The RT5X00 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 RT5X00 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.

*Note: It is important that the minimum output adjust is not taken below 10.8V (12V Nominal) and 21.6V (24V Nominal). Setting the output voltage below this level may result in the module being permanently damaged.
- Power Classification
The RT5400 and RT5300 classification is fixed at Class 4, this means that an IEEE802.3at Type 1 or an IEEE802.3af PSE will default to Class 0. However an IEEE802.3at PSE will recognise the Class 4 as a Type 2 PD.
