Military-Grade Power Solutions

For Airborne Environments

Airborne equipment needs to be engineered to the highest standards possible. The aerospace industry relies on sophisticated electronics for monitor displays, communication systems, radar and navigation equipment, and many other devices that are critical to in-flight operations. Power supplies that run these precision-critical electronics must be consistently reliable under any operating condition.

For decades, we’ve been a proud partner to the military and aerospace industry, providing ruggedized, reliable power solutions compliant with MIL-STD-704 and other relevant military standards. As a leading supplier of military power solutions, let us help assess your needs and select or build the right power supply system to meet your requirements and schedule.

Types of Aerospace & Military Aircraft Power Supplies

The specific environmental conditions encountered in air call for engineered aerospace power supplies that meet precise requirements for size, weight, efficiency, hermeticity, and ruggedization. As aerospace electronics become more advanced, aircraft power supplies become more complex in order to provide sufficient power in flight. Today’s aviation power supplies must provide greater current at low voltages without comprising design and performance requirements.

What is MIL-STD-704?

MIL-STD-704 establishes the input electrical requirements of aerospace power supply standards for military aircraft used in the Air Force, Army, Navy, Marine Corps, and Coast Guard. This military standard sets out the input characteristic the power supply must operate under whether on the ground, inflight or take-off and landing. The additional handbooks MIL-HDBK-704-1 through -8 define the test methods and procedures used to determine compliance with MIL-STD-704. By using a MIL-STD-704 power supply, you’ll have a level of performance that’s suitable for use in airborne applications.

Engineered Power Solutions for the Aerospace Industry

At ACT, we design and manufacture MIL-STD-704 AC-DC and DC-DC power supplies that can be used in military aerospace applications—those manned and unmanned, inhabited and uninhabited. Our airborne solutions meet these stringent standards and are quality-tested to ensure the highest performance and reliability. They’re also:

  • Engineered to withstand harsh conditions, including high altitudes, extreme temperatures, moisture, shock, and vibration
  • Equipped with advanced features such as remote on/off, short circuit, reverse polarity, overload protection, output holdup capacity, and many additional features
  • Available in multiple input/output voltage configurations

Our premier, MIL-STD-704 compliant, custom airborne power solutions also meet the needs for powering this demanding domain in the following ways:

  • Environmental ruggedness: aircraft military power supply systems must meet tough environmental specifications under MIL-STD-810 standards, including maximum and minimum operation and storage temperatures, high altitudes, humidity levels, vibration, and shock. Our airborne power supplies are designed with rugged construction to withstand -40°C to +85°C storage temperatures and altitudes as high as 80,000 ft. Our military-grade power solutions are also available in hermetically-sealed modules to protect against humidity, dirt, and dust.
  • Adaptable unit shape and size: ACT custom power supplies can be built to match many size, weight, and space requirements. Our advanced machining capabilities allow us to create unique form factors that can be easily integrated into your aircraft design, where space is limited. Our engineered solutions make the most of the space available while providing the dependable performance necessary in an airborne environment.
  • EMI filtering: sensitive mission-critical equipment must be protected from electromagnetic interference (EMI) that can damage equipment and cause malfunctions. ACT custom power supplies offer built-in EMI filters to protect aircraft electronics from general noise interference to meet MIL-STD-461 standards for security and reliability.

If you’re looking for a ready-to-ship power solution, check out our available AC-DC MIL-COTS and DC-DC MIL-COTS power supplies. All are ruggedized and designed to meet military standards. You can quickly modify a COTS power supply by making it a MOTS, Modified-Off-The-Shelf, solution to meet your aerospace environmental requirements and adhere to your program timeline.
