Military systems require power supplies that consistently provide performance in the most demanding applications. This is one of the reasons that the military has standards to cover input parameters that power supplies see—MIL-STD-1275, MIL-STD-1399 and MIL-STD-704. There are also military specifications describing the various environments such as MIL-STD-810 and MIL-S-901. Defense contractors rely on these standards to ensure they receive a product that can meet the challenges inherent in combat situations, whether they involve extremes of temperature or humidity or protection from electromagnetic interference. There are also industrial standards the military uses to take advantage of “commercial” products such as the VITA standards (VMEbus International Trade Association).
Designing military power supplies requires balancing electrical performance with survivability under harsh operating conditions. Engineers typically evaluate input transients, voltage spikes, power quality (including harmonic distortion), EMI susceptibility, thermal performance, and mechanical ruggedization. Requirements often vary by platform (air, land, sea) and by applicable standards such as MIL‑STD‑1275, MIL‑STD‑704, and MIL‑STD‑1399, along with environmental expectations like MIL‑STD‑810. A strong military power supply design also considers integration constraints (form factor, mounting, connectors) and long lifecycle support.
Army and ground vehicle systems often experience demanding electrical conditions such as high voltage spikes, low-voltage transients, vibration, shock, and extreme temperature exposure. For these environments, teams frequently look for power solutions aligned to MIL‑STD‑1275 and MIL‑STD‑810 expectations to reduce program risk and improve field reliability. ACT supports rugged AC‑DC and DC‑DC power supply configurations for ground platforms depending on integration and performance requirements.
Advanced Conversion Technology (ACT) manufactures a wide range of high-reliability military power supplies. Our products are used to power critical devices such as communications and navigation systems in military ships, army vehicles and other applications where performance is essential.
Key products include:
A key feature of all our products is a high degree of application specificity. Our custom military power supply units can be configured with a variety of input and output voltage levels. We design and sell VME rack power supplies as well as benchtop systems in multiple sizes.
The ability to withstand extreme conditions is a key requirement of compliance with military standards for power supply systems. Our products can be housed in ruggedized frames to provide dependable performance when exposed to vibration, shock or other impacts. We design military rack mount power supplies that can be used in temperatures ranging from -55 to 105°C, as well as in high humidity or extremely arid conditions.
Other notable features of ACT military power supply systems include:
Our products meet MIL-STD-1399 harmonic distortion standards, MIL-STD-810 standards for environmental design and MIL-STD-461 standards for electromagnetic interference. Browse our AC‑DC power supplies and DC‑DC power supplies, or talk to an engineer to review your requirements.
