摘要： A system is disclosed for controlling operation of an LED lighting system, including a Power over Ethernet (PoE) LED driver couplable to a PoE switch via a power and communication link. The PoE LED driver includes a microcontroller for controlling an LED driver chip to operate an associated LED lighting fixture. A voltage and current measurement unit is coupled to the microcontroller to receive power from the power and communication link, and to provide signals to the microcontroller. The provided signals can be representative of an input electrical parameter of the power and communication link. The microcontroller is programmed to compare the signals representative of the input electrical parameter against a predetermined value, and command operation of the LED driver chip based on the comparison.
