Abstract
A system and method are provided for displaying electronic devices operable when electrical power is supplied to them at respective operating voltages through respective power connectors. The system has a power supply providing input electrical current at a first voltage and cable structures each connected with the power supply and having a respective power connector electrically connecting with the power receiving structure of one of the electronic devices. The cable structures each include a voltage regulator system that receives the input electrical current, converts it to an output electrical current at an output voltage, and transmits it to the power connector, so as to transmit an operating electrical current to the associated electronic device. The voltage regulator system sets the output voltage of the output electrical current such that the operating electrical current delivered to the associated electronic device has a voltage that corresponds to the operating voltage of that device. This is accomplished by connecting the voltage regulator to a calibrating component with a selected electrical characteristic that sets the output voltage. A security circuit creates an alarm when separation of the electrical device from the system occurs.
