Title:
通信ケーブルを介して搬送される電力を制御するための方法及びシステム
Document Type and Number:
Japanese Patent JP6587256
Kind Code:
B2
Abstract:
Power over Ethernet (PoE) communication systems, control circuits and methods are presented for controlling power delivered to a powered device through a communication cable, in which a power sourcing equipment measures a supply voltage and selectively discontinues provision of power from a power source in response to a measured supply current exceeding an adaptive limit signal representing a supply current level corresponding to a predetermined safe operating power level at the measured supply voltage.
