Abstract
A remote power supply arrangement for graphical display systems. The remote power supply places one or more power supplies in a separate location, some distance apart from the graphical display, rather than within the display cabinet or module itself. Power is then transferred from the power supply to the display by electrical cords. The remote power supply provides lighter weight displays, less noise near the displays, and improved maintenance and repair. The invention includes apparatus, methods of providing remote power to displays.
Claims8
graphical display apparatus comprising a display having a plurality of:
- display modules, and a remote power supply.
Graphical display apparatus comprising a remote power supply and a local power distribution board.
Graphical display apparatus having redundant power supply with a plurality of power units, and a power integration and switching system which adapts the redundant power supply to accommodate a failure in a power unit by supplying power from non-failed power units to seamlessly provide power to a graphical display during such failure condition.
A method of providing power to graphical display comprising the steps of:
- a. providing a remote power supply and a power transmission cord and a power distribution system and a plurality of display modules;
- and,
- b. using the remote power supply to provide power to the plurality of display modules by transmission via the power transmission cord and the power distribution system.
A method of maintenance of a graphical display maintenance comprising the steps of:
- a. providing a remote power supply having a plurality of power units and a power integration and switching system and providing a power transmission cord and a power distribution system and a plurality of display modules;
- b. using the power integration and switching system to supply power to the display modules during a failure of one of the plurality of power units;
- and,
- c. replacing the failed power unit.
A method of maintenance of a graphical display maintenance comprising the steps of:
- a. providing redundant power supply with multiple components, and providing a plurality of display modules;
- b. using the redundant power supply to supply power to the plurality of display modules during a failure of one of the multiple power supply components;
- and,
- c. replacing the failed power supply component.
