Resolving extreme environmental sealing, thermal dissipation, electromagnetic compliance, and electrical transient challenges in battlefield-deployed defense platforms.
Modern electronic combat systems, mobile radar arrays, ground tactical vehicles, and shipboard deck equipment must operate continuously in severe environments where airborne salt fog, mud, torrential rain, and chemical washdowns are routine. When specifying a Military Sealed IP67 Power Supply, defense buyers face a critical technical paradox: how to deliver thousands of watts of regulated AC-DC or DC-DC power inside a completely ingress-sealed enclosure without active cooling fans, while simultaneously satisfying strict MIL-STD requirements.
Standard industrial power units rely on high-CFM internal fans to draw ambient air directly across aluminum heat sinks and magnetics. In tactical defense applications, open ventilation is impossible. Exposure to particulate dust, sand, standing water, or chemical decontamination protocols demands an IP67 enclosure capable of enduring temporary submersion at 1-meter depth for 30 minutes.
AJ's Power Source Inc. (AJPS) resolves this thermal barrier through specialized conduction-cooling topologies, high-conductivity dielectric encapsulation (potting), and micro-channel aluminum housing extrusions. Every watt of internally dissipated heat is efficiently transferred from switching semiconductors to the outer chassis baseplate, enabling fanless continuous operation across ambient temperatures from -40°C to +85°C.
Achieving an IP67 rating is only one component of military compliance. A true Military Sealed IP67 Power Supply must pass an extensive battery of electromagnetic, environmental, and electrical input qualification tests.

Engineered specifically for heavy tactical land vehicles and autonomous unmanned ground platforms. Accepts raw 28 VDC vehicle power subject to severe transients and regulates high-current output for mission computers, communications arrays, and weapons turrets.
A versatile, fully potted brick supply delivering reliable isolated DC power from global AC grid or generator sources. Built for exposed mast mounting, field shelters, and naval topside equipment exposed to extreme weather.
Designed for aircraft payload bays and unpressurized avionics compartments. Accepts 270 VDC high-voltage DC or 115 VAC 400Hz aircraft power, delivering tightly regulated, low-noise DC rails for radar and electronic warfare suites.
Engineered for naval surface combatants and amphibious assault craft. Integrates seamlessly into zonal electrical distribution schemes, converting 115V/440V 60Hz shipboard power into clean 28VDC tactical power on weather decks.
The global market for defense power conversion equipment is undergoing a rapid transition. Procurement teams across prime defense contractors, international ministries of defense, and military integrators are re-evaluating power system specifications driven by three macro forces:
Military procurement directives increasingly demand Modular Open Systems Approach (MOSA) and Sensor Open Systems Architecture (SOSA) alignment. Systems integrators want modular Military Sealed IP67 Power Supply units that can be upgraded or swapped across platforms without altering mechanical enclosures or recertifying entire vehicles. AJPS designs standardized COTS/MOTS base modules that fit standard physical envelopes while allowing custom connector keying and rail configurations.
Next-Generation Squad Vehicles (NGSV), Unmanned Ground Vehicles (UGVs), and hybrid-electric tactical fleets operate with elevated DC bus voltages (ranging from 270 VDC up to 600 VDC) to drive traction motors. However, onboard C4ISR, communications, and sensor packages still mandate clean 28 VDC power. Procurement teams are seeking high-efficiency, wide-input step-down IP67 DC-DC power converters capable of handling extreme voltage ranges while isolated inside liquid-cooled or conduction-cooled sealed housings.
Geopolitical tensions have heightened scrutiny over power electronics supply chains. Defense buyers are moving away from offshore commercial component vendors to mitigate the risk of counterfeit semiconductors, cyber-vulnerabilities, and supply delays. Procurement specs now explicitly require USA-designed and manufactured power supplies from established Veteran Owned Small Businesses (VOSB) with CAGE code registration (such as AJPS CAGE 0P327) and full component lot traceability under ISO 9001 management systems.
Modifying a proven COTS/MOTS IP67 platform yields up to 70% reduction in Non-Recurring Engineering (NRE) costs and reduces schedule risk by 6 to 9 months compared to clean-sheet custom developments.
Send an InquiryTo meet rising power density demands in constrained defense envelopes, power engineering is evolving across semiconductors, thermal materials, and digital telemetry.
Replacing legacy silicon MOSFETs with Gallium Nitride (GaN) and Silicon Carbide (SiC) devices dramatically reduces switching losses and gate drive power. Higher switching frequencies (500 kHz to 1+ MHz) shrink transformer magnetic footprints by up to 40%, directly enabling higher power output inside compact IP67 sealed housings.
Modern potting compounds have evolved beyond standard epoxies. Next-generation IP67 military power supplies utilize specialized thermally conductive silicone elastomers (up to 3.0 W/m·K) that remain resilient down to -55°C while dampening structural resonance during extreme vibration under MIL-STD-810H Method 514.8.
Sealed power supplies no longer operate as silent "black boxes." Modern military units feature galvanically isolated PMBus or CANbus interfaces integrated into the IP67 connector block, reporting real-time baseplate temperature, load current, input voltage health, and operational hours to vehicle system computers for predictive failure monitoring.
