ABSTRACT:
A flexible cable is provided for a lighting system having a power supply that includes a power supply input to receive a first signal having a first frequency and a circuit for converting the first signal to a second signal, and at least one luminaire coupled to a lamp driver. The cable comprises a first leg of wires for carrying the second signal. The first wire electrically connects a loop output of the power supply to an input of the lamp driver and a second wire electrically connects an output of the lamp driver to a loop return of the power supply. The cable further comprises a second leg of wires electrically connected to a ground of the power supply and the ground of the lamp driver. The second signal has a substantially constant current and a second frequency distinctly higher than the first frequency. The flexible cable further comprises a modular connector.
