Uninterruptible Power Supply

Earl Integrated Power & Controls, a division of Earl Industries (Portsmouth, VA), was enlisted by the U.S. Navy to create an innovative, vertically mounted voice-data-video (VDV) network node for the Ford Class Aircraft Carrier. One of the major challenges in this endeavor was that the rugged uninterruptible power supply (UPS) required to power the system would have to be equally innovative, owing to the node’s vertical orientation; the need for extended battery backup runtime; quick replacement of the unit’s power factor correction board; access to the Ethernet switch; and limited space availability.
