Defense Electronics & Military-Grade Power Electronics Solutions
Military defense operations demand unwavering electrical reliability under extreme operating conditions. Standard commercial power electronics are inadequate when exposed to physical impact, severe thermal variations, moisture ingress, electromagnetic interference (EMI), and transient electrical surges. Aegis Power Systems specializes in designing, prototyping, and manufacturing ruggedized military power supply units (PSUs) and DC-DC converters built specifically to survive mission-critical environments.
With over 30 years of specialized power conversion engineering experience, our technical team serves defense prime contractors, tier-1 system integrators, and military research agencies globally. From tactical ground vehicles and airborne surveillance systems to naval combat vessels and missile guidance platforms, Aegis Power Systems delivers ruggedized AC-DC power supplies, high-density DC-DC converters, SOSA-aligned VPX units, and custom-engineered power distribution equipment.
Compliance with Strict Military & Defense Specifications
Every military power supply designed by Aegis Power Systems is rigorously engineered and qualified to satisfy critical United States Department of Defense (DoD) standards and international military requirements. Our design practices ensure compliance across environmental, electrical input, and electromagnetic compatibility parameters:
MIL-STD-810
Environmental engineering considerations including extreme operating temperatures (-40°C to +85°C), high shock/vibration profiles, humidity, salt fog, and altitude exposure.
MIL-STD-461
Comprehensive Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) control for conducted and radiated emissions and susceptibility.
MIL-STD-704
Airborne electrical power characteristics including steady-state voltage levels, transient surges, phase unbalance, and frequency variations for 28VDC, 115VAC, and 230VAC systems.
MIL-STD-1275
Ground vehicle 28VDC electrical input characteristics, protecting downstream electronics against severe initial engagement surges, voltage spikes, and reverse polarity.
MIL-STD-1399
Naval shipboard interface standards for AC power systems, ensuring low harmonic distortion, voltage spike immunity, and high isolation under harsh sea-going conditions.
MIL-PRF-GCS600A
Performance specifications tailored for tactical ground command platforms and mobile defense computer architecture power requirements.
