PRESS RELEASE

Date: March 21, 2006

BEHLMAN Hauppauge, New York, March 21, 2006— Behlman Electronics Inc., known     for its leadership in providing power products for industrial, commercial and military applications,

has been awarded a follow-on contract to provide Behlman 94012-MK-119 Power Supply System

for use on the U.S. Navy AEGIS Destroyer MK-119 Fire Control Systems.

Behlman was originally awarded a contract to design a form-fit-function replacement MK-119

power supply system for the Navy’s systems integrator when the original manufacturer went

out of business. Behlman responded by building, testing and delivering a first article

94012-MK-119 system in just 90 days. As a result of the improved performance and

cost-savings made possible by the modified COTS design of Behlman’s power supply system, Behlman was subsequently asked to manufacture a replacement 3000 VA uninterruptible

power source (the Behlman UPS-3000) for the MK-119 Fire Control System.

“Our ‘can do’ attitude and ability to get things done on the first contract resulted in multiple

additional production contracts with the systems integrator and the Navy,” explained Behlman

Vice President of Sales and Marketing Ron Storm. “We’ve proven our ability to deliver,

and the MK-119 Power Supply System has proven itself able to withstand the rigors on board

U.S. Navy warships.”

The Behlman 94012-MK-119 Power Supply System features a modular design with three

load-sharing, line replaceable units (Behlman 94016-MK-119 LRUs). In the event of the loss

of one LRU, the remaining two LRUs can support the full load while the third unit is hot-swapped (replaced without shutting down power on the system). The ruggedized, modified COTS LRUs

are N+1 redundant and feature current sharing, front panel status indicators and internal fans for cooling.

Behlman’s 94012-MK119 Power Supply System is rack mountable (19” rack mount chassis, 3U)

with an option for slides, and is designed to meet MIL-STD-1399 and MIL-STD-461 specifications.

The Behlman UPS-3000 is a ruggedized, true on-line UPS with five minutes of hold-up time at

3000 VA. It provides protection against short-circuits and other power problems including noise,

sags, surges, transients, frequency changes, high/low voltages, lightning, blackouts and

harmonics. This UPS is designed to meet MIL-STD-1399 and MIL-STD-461 specifications,

and is used by the Navy to power the Behlman 94012-MK-119 Power Supply System,

in addition to other 120 VAC, 60 Hz equipment in the MK-119 Fire Control System.
