The ZIG-POEPRO-100A (Tx) provides a complete solution for detection and powering of POE IEEE 802.3af devices such as the ZIG-POEPRO-100A (Rx). The ZIG-POEPRO-100A (Tx) POE solution will safely detect, classify, and provide 48V up to 25W power to RX device connected to the HDBaseT port. The Tx unit will first read a signature from the Tx and only enable power delivery if all constraints are met. During the power delivery the link is continuously monitored for any fault or overloading conditions and the current is limited to avoid hazardous conditions. The ZIG-POEPRO-100A (Tx) senses the removal of a powered device and turns off 48V power immediately when the Rx is disconnected.
