POWER ELECTRONICS: Navy chooses Behlman power supplies to keep aging shipboard displays in working order

U.S. Navy officials needed large power supplies to keep aging AN/UYQ-21(V) shipboard display systems operational. They found their solution at Behlman Electronics Inc. in Hauppauge, N.Y. Behlman received follow-on orders for the company's model 94020 power electronics device for the UYQ-21(V) display system.

The UYQ-21(V) displays are aboard several Navy surface warships, including Ticonderoga-class cruisers, Arleigh Burke-class destroyers, Oliver Hazard Perry-class frigates, Wasp-class amphibious assault ships, and Nimitz-class aircraft carriers. The displays need high-power electronics control to keep old cathode ray tube (CRT) screens running.

The aging display systems in recent years have had problems with their aging power supplies, which no longer have manufacturer support. Behlman engineers adapted the Model 94020 high-voltage commercial off-the-shelf (COTS) power supply to match the size, shape, and performance requirements of the UYQ-21(V) display system.

Tests eventually led to Navy approval of the Behlman 94020 design. Production and delivery began in 2007. The Behlman power supply has proven itself in real-world operation, and the company has received additional orders for delivery in 2012.

The Behlman 94020 power supply operates from a 28-volt DC input; supplies four high-voltage outputs with levels as high as 25,000 volts DC to power the UYQ-21(V)'s color CRT display; and is a rugged design suited to withstand the rigors of shipboard combat operations.
