SYSTEM FOR SUPPLYING AC POWER TO A DISPLAY VIA A LOW VOLTAGE CABLE

摘要

A system for supplying AC power to a display via a CAT7 or similar low voltage cable comprises a transmitter connected to an AC power outlet and generating DC voltage transmitted by the CAT7 cable to a receiver. The receiver converts the DC voltage to AC voltage and supplies AC power to the display. A limiting circuit limits power transmitted by the CAT7 cable to a predetermined wattage, depending on the feedback from the receiver, which insures safe operation of the system. Power from the display is disconnected if a pre-programmed power consumed by the display is exceeded or falls below a predetermined threshold.
