Military-Grade AC-DC Power Supplies

For decades, we’ve been engineering and manufacturing rugged, military-grade AC-DC power supplies for mission-critical military applications. Based on our field-proven expertise, we’ve developed AC-DC COTS (Commercial Off-The-Shelf) power solutions to meet the requirements of a wide range of military standards, including MIL-STD-704, MIL-STD-1399, MIL-STD-461, and MIL-STD-810. Our MIL-COTS (Military-COTS) power systems are offered in a rugged natural convection or conduction packages and can be customized to be rack-mounted or rugged frame-mounted. For maximum flexibility in your high-end industrial or military application, we offer designs including an active power factor correction (PFC) front end.

Our AC-DC MIL-COTS line of products are quick reaction ready, ruggedized, and tested to meet military standards. They offer reliable and affordable power system options and are available for purchase now. Check out our available AC-DC MIL-COTS power solutions below.

Make It a MOTS

The military needs power supplies that perform reliably in a wide range of challenging conditions. The right power supply helps keep equipment functioning properly in the field. MOTS, or Modified Off-The-Shelf, power supplies are adapted, ruggedized, and designed to meet the unique demands of your military application. Typically derived from COTS, the main advantage of a MOTS power supply is adaptability. They’re the fast, budget-friendly answer for meeting your power and environmental requirements.

 At ACT, our MOTS power supplies are fully capable of meeting your expectations for performance and protection. Talk to us today about making a COTS power solution a MOTS power solution specific to your application needs.

Custom AC-DC Product Solutions

Our single and multi-output military power supplies are designed and built under one roof in the USA and are relied upon for land, sea, and air operations around the globe. Our engineers have designed and built numerous custom military-grade AC-DC power supplies and military power converters to meet one of the primary AC input power specifications: MIL-STD-704 (aircraft) and MIL-STD-1399 (shipboard). Packaging options have included rack mounted, bench mounted, or ruggedized frame mounts.

From 1 to 3 phase inputs, 60 Hz or 400 Hz, we can provide you with a design to meet your custom power supply needs. We can also incorporate an active PFC front end, which provides less than 3% total current harmonic distortion. We specialize in 3 phase, 400 Hz power supply products, and provide a full range of product options for your application.

ACT power products have been deployed to applications that are in severe environments. We have AC-DC military power supplies that have been tested to many levels of the shock and vibration requirements of MIL-STD-801, MIL-STD-202, and MIL-STD-167 and the high impact shock requirements of MIL-DTL-901. Since electromagnetic interference is also a concern for the military, our products can be designed and tested to any or all of MIL-STD-461. Our products are capable of operating in environments with temperature ranges from -55 °C to +105 °C and high altitude up to 100,000 ft, including applications that require hermetically sealed enclosures.
