Astronics Corporation Introduces New 150W DC Power Supply

EAST AURORA, NY, May 18, 2010 – Astronics Corporation (NASDAQ: ATRO), a leader in
advanced, high performance lighting, electrical power generation / distribution and automated test
systems for the global aerospace and defense industries, today announced a new product addition
to their world leading intelligently managed power solutions. This new AC to DC power supply
converts 115VAC, 360Hz to 800Hz aircraft power to 150 Watts of +28VDC. The power is provided
by four individual +28VDC outputs current limited at 1.5Amps each. This is all accomplished in a
compact and lightweight product that meets the stringent requirements of the aviation environment
and the OEM’s. The outputs may be paralleled to create a single 150 Watt output and multiple units
may be used in parallel to create 300 Watts or 450 Watts with current sharing. The unit provides
hold-up of the outputs to 200 mSec so that connected devices stay powered during normal bus
transfers and power interruptions.

This new power supply (P/N 1314-3) is in direct response to increasing market demand and
customer feedback. Airline seat manufacturers, seat motor actuator manufacturers, in-flight
entertainment suppliers, and aircraft OEMs around the world have requested Astronics develop a
universal AC to DC power supply that addresses multiple applications. Using the same highly
reliable technology, high efficiency, and quality as other EMPOWER® products, Astronics has
developed a small and lightweight unit for multiple applications. As airlines continue to demand
smaller, innovative, and lightweight system architectures, Astronics continues to develop and
provide power solutions such as the 1314-3 150W DC Power Supply.

“Our customers bring us opportunities and we provide them with rapid innovative solutions. Attention
and responsiveness to our customer needs have propelled Astronics to our market leading position
for power products.” said Dennis Markert, Director, Business Development of Astronics Cabin
Electronics group.

Astronics is the market leader in bringing intelligently managed power to passengers and airline
personnel. Astronics EMPOWER® in-seat power systems are used to enhance passengers’ flying
experience by powering their personal electronic devices and laptop computers as well as aircraft in-
flight entertainment systems. The Company’s systems have been installed on over 140 airlines to
power over 500,000 seats.
