Explore our specialized portfolio of CE Certified, IP67 ruggedized power supply units, high-power GaN RF modules, tactical defense hardware, and passive spectrum protection systems engineered for mission-critical reliability.
Modern industrial automation, defense systems, naval vessels, and remote communications demand power electronics that operate flawlessly under severe environmental stress. CE Certified IP67 power supplies represent the apex of ruggedized electrical engineering, combining stringent European safety and electromagnetic compatibility standards with absolute protection against dust ingress and liquid immersion up to 1 meter depth.
Engineered for zero-failure operating environments, high-reliability IP67 power conversion units bypass standard commercial design limitations. By utilizing advanced encapsulation compounds, conduction-cooled thermals, and Gallium Nitride (GaN) power semiconductors, tier-1 manufacturers deliver high power density within compact SWaP-C (Size, Weight, Power, and Cost) envelopes.
100% dust-tight construction with continuous water immersion tolerance up to 1m. Potted chassis configurations prevent moisture condensation, salt-fog corrosion, and mechanical shock strain.
Gallium Nitride (GaN) High-Electron-Mobility Transistors deliver over 94% switching efficiency, drastically reducing thermal dissipation requirements in sealed, fanless power enclosures.
Fully compliant with EU Directives 2014/30/EU (EMC) and 2014/35/EU (LVD), while engineered to meet stringent MIL-STD-810H environmental and MIL-STD-461G EMI/EMC parameters.
The industrial power supply landscape is undergoing a massive architectural shift driven by electrification, autonomous systems, and anti-drone defense deployments. Original Equipment Manufacturers (OEMs) and defense integrators can no longer rely on conventional forced-air cooling systems, which introduce ingress vulnerabilities and moving-part failure points.
Eliminating internal fans is mandatory for true IP67 compliance. However, sealed aluminum enclosures create thermal dissipation bottlenecks. Leading manufacturers utilize high-thermal-conductivity silicone or epoxy potting compounds (exceeding 2.5 W/m·K) to transfer internal heat directly to the exterior chassis. Conduction-cooled cold plate designs allow high-wattage power supplies (up to 2500W) to operate reliably at full load across ambient temperatures from -40°C to +85°C.
In counter-unmanned aerial vehicle (C-UAV) and FPV defense systems, solid-state RF power amplification requires steady, ultra-clean DC power delivery. Integrating Gallium Nitride (GaN) modules operating across broad frequency spectrums (such as 433MHz, 1.2GHz, and 700–6000MHz) demands power stages capable of handling high crest factors and rapid load transients without output voltage droop or harmonic distortion.

As international procurement agencies update their supply chain requirements, two key trends dominate the IP67 power converter market:
Building custom power supplies from scratch incurs significant Non-Recurring Engineering (NRE) costs and prolongs qualification timelines by 12 to 18 months. Modern defense and industrial buyers heavily favor Commercial-Off-The-Shelf (COTS) and Modified-Off-The-Shelf (MOTS) platforms. By starting with proven, pre-certified IP67 base models and modifying output rail configurations, connector types (such as MIL-DTL-38999 circular connectors), or conformal coatings, programs achieve field compliance in a fraction of the time.
With the rapid proliferation of autonomous systems, power delivery networks must now support co-located passive RF detection hardware and high-power anti-drone jamming modules. Modern power architectures integrate dual-mode power conversion, allowing low-power passive spectrum monitoring (consuming under 5W) to instantly trigger multi-kilowatt GaN power amplifiers within milliseconds when a threat is identified.
Established in 1987, AJ's Power Source Inc. (AJPS) is a Veteran Owned Small Business (VOSB), registered under CAGE Code 0P327, dedicated exclusively to the design, integration, and manufacturing of ruggedized power conversion systems. Our engineering capabilities span over three decades of field-proven deployment across naval ships, airborne platforms, ground tactical vehicles, and harsh industrial automated plants.
Fully registered quality management system audited by PJR with ANAB accreditation, ensuring 100% trace-ability, rigorous component screening, and zero-defect manufacturing standards.
Equipped with thermal shock chambers, vibration tables, EMI pre-compliance receivers, and ingress test rigs to validate MIL-STD-810, MIL-STD-461, and IP67 parameters prior to formal delivery.
We guarantee long-term program support with form-fit-function replacement paths, protecting long-lifecycle industrial and defense investments against component end-of-life risks.
IP65 ratings guarantee protection against low-pressure water jets from any direction. IP66 protects against high-pressure water jets and heavy seas. IP67 certification goes further by guaranteeing complete dust tightness (6) and total protection against water immersion up to 1 meter depth for 30 minutes (7), making IP67 the standard for submersible, deck-mounted, or extreme wash-down environments.
Gallium Nitride (GaN) technology allows RF power amplifiers to operate at higher voltages, higher temperatures, and higher switching frequencies than traditional Silicon (Si) or GaAs transistors. This results in significantly higher power density, broader bandwidth coverage (e.g., 700–6000MHz in a single module), and higher energy efficiency, which is critical for battery-powered or vehicle-mounted C-UAV systems.
Yes. Through our MOTS (Modified-Off-The-Shelf) engineering program, standard AC-DC and DC-DC power converter chassis can be configured with custom output voltage rails (e.g., 12V, 24V, 28V, 48V, or high-voltage DC), custom circular connectors, specific hold-up times, and tailored EMI filtering circuits to match your system specs.
Our power conversion units are engineered to meet the essential requirements of the European Union Low Voltage Directive (LVD 2014/35/EU), Electromagnetic Compatibility Directive (EMC 2014/30/EU), and Restriction of Hazardous Substances (RoHS 3 Directive 2015/863), ensuring smooth international deployment and customs clearance.
Thermal energy is managed via full internal potting with high-grade thermally conductive polymers combined with heavy-duty aluminum conduction baseplates. Heat flows naturally from internal power components through the potting media to the outer casing, which dissipates thermal energy via natural convection or cold-plate mounting.
Whether you require standard CE Certified IP67 power supply units, customized GaN RF defense modules, or full MIL-STD environmental qualification packages, our senior application engineers are standing by.
