Who We Are

Founded in 1981, ACT is a Middletown, PA-based company specializing in the design and manufacture of precise, high quality power systems. Though our primary customer base is the defense industry, we are well-positioned to meet the needs of clients in civilian aerospace and aviation.

All of our aircraft power supply products are built in our 63,000 square foot facility — a high degree of vertical integration gives us precise control over all aspects and stages of the manufacturing process. As a result, we can provide shorter lead times while ensuring a high level of quality control. Our quality system is certified to AS9100.

Aerospace Power Supply

The specific environmental conditions encountered on military and civilian aircraft call for engineered aerospace power supplies that meet precise requirements for size, weight, efficiency, hermeticity and ruggedization. The more sophisticated and integrated aircraft electronics become, the more difficult it is to balance these concerns with the need for sufficient power in-flight. Today’s aviation power supplies must provide greater current at low voltages without compromising design requirements.

The standards outlined in MIL-STD-704 provide an excellent guide for the electrical requirements of aerospace power supplies. MIL-STD-704 sets out normal operating characteristics and requirements for input transient, maximum allowable distortion, acceptable limits for over- and under-voltage, and more. By using a MIL-STD-704 power supply, you’ll have a level of performance that’s suitable for use in aerospace applications.

Types of Aerospace & Military Aircraft Power Supplies

Aerospace equipment and military aircraft need to be engineered to the highest standards possible. Power supplies that run precise radar and navigation equipment must be reliable and consistent under any operating condition. At the same time, however, contractors need to keep costs in check.

An aerospace power supply doesn’t have to be expensive or complicated. Advanced Conversion Technology (ACT) is a leading supplier of MIL-STD-704 AC-DC as well as DC-DC converters and other products for aircraft and aerospace manufacturers. Let us help you assess your needs and select the right power supply system for you based on the revision level of the standard you need.

What is MIL-STD-704?

MIL-STD-704 is a military standard that sets acceptable characteristics for aircraft electric power provided to the input terminals of equipment used in aircraft and aerospace applications. It provides requirements for operation, compatibility, power utilization and testing for all single-phase or three-phase wire-connected, grounded neutral systems. Among the considerations when sourcing a MIL-STD-704 power supply are input transient handling, maximum distortion allowed, acceptable limits for voltage, under voltage conditions, and a variety of demanding requirements.

ACT provides a number of products that meet MIL-STD-704 standards, including 270VDC power supplies; 3-phase, 115 VAC 400 Hz power supplies; and 115 VAC 60 Hz power supplies. Our products can be found in many military aircraft, where they are essential to providing dependable power for displays, communications systems and other electronics.

MIL-STD-704 Power Supply Products

ACT manufactures several MIL-STD-704 power supply products that can be used in military aerospace applications. When you need reliable power for communications systems, monitor displays or other low-voltage devices, we can match you with the right product for your project. Our military-grade aerospace power supply products are:

  • Engineered to withstand even the harshest conditions, including high altitudes, extreme temperatures, moisture, shock and vibration, to name a few
  • Equipped with advanced features such as remote on/off, short circuit, reverse polarity overload protection, and many additional features.
  • Available in multiple input/output voltage configurations
  • Designed and tested in our Middletown, PA facility

We offer MIL-STD-704 AC-DC converters, DC-DC power supplies and more. Browse our website to view our complete list of product offerings, or contact a representative for more information.

Engineered Solutions for the Aerospace Industry

ACT is not limited to providing off-the-shelf MIL-STD-704 power supplies. We understand that our aerospace clients may have specific requirements that make MIL-STD-704 a mere starting point. Many of our products can be further modified to meet your needs, or our team can engineer a custom power solution from the ground up. Whatever requirements you have, our expertise and advanced production capabilities can provide you with a rugged, reliable and cost-effective power supply solution.

Trust ACT With Your Power Supply Needs

The majority of equipment failures in military aircraft are due to design and engineering shortcomings that lead to transient spikes, voltage surges and other power irregularities. For this reason, a power supply you can trust is essential when designing and manufacturing new equipment.

Since 1981, Advanced Conversion Technology has been a leading manufacturer of aerospace power supply equipment that meets MIL-STD-704 and other requirements. Our engineering team has a combined 300 years of experience, and we’ve invested in our vertical manufacturing capabilities to provide comprehensive in-house design and acceptance testing for everything we sell.

A smaller supply chain not only keeps costs down, it allows us to provide the highest possible level of quality control over every aspect of a device. All our aerospace power supplies are extensively tested and can be modified in various ways to better suit your needs.
