Aero Engineering Focus

Mission-Critical Power for Modern Airborne Envelopes

AJ's Power Source Inc. (AJPS) designs, validates, and manufactures advanced Aerospace Grade and Commercial Off-the-Shelf (COTS/MOTS) power electronics engineered for extreme operating conditions. Designed with rigorous adherence to Size, Weight, Power, and Cost (SWaP-C) requirements, our power platforms deliver maximum power density and exceptional Mean Time Between Failures (MTBF).

Whether powering advanced avionics suites, radar arrays, satellite ground terminals, tactical UAV ground stations, or onboard communications, AJPS platforms provide total immunity to severe voltage transients, frequency fluctuations, shock, and extreme thermal cycling.

  • MIL-STD-704 Compliance: Designed for 115V/230V 400Hz AC and 28VDC / 270VDC airborne power buses.
  • Harsh Environment Protection: Baseplate conduction cooling, sealed IP67 options, and conformal coating.
  • Rapid Qualification: Field-proven modular topologies reduce Non-Recurring Engineering (NRE) costs and lead times.

B2B Buyer FAQs

Frequently Asked Questions by Aerospace Engineers & Buyers

Our aerospace power platforms are engineered to meet MIL-STD-704 (A-F) guidelines for 115V 400Hz AC, 28VDC, and 270VDC inputs. In addition, systems are designed to satisfy MIL-STD-461 EMI/EMC requirements and MIL-STD-810 environmental testing for temperature, altitude, vibration, and acceleration profiles.

Yes. SWaP (Size, Weight, and Power) optimization is at the core of our engineering approach. By utilizing high-frequency planar transformers, conduction baseplate cooling, and specialized aluminum alloy enclosures, we maximize power density for uncrewed aerial vehicles (UAVs), rotary aircraft, and tight avionics bays.

Absolutely. Starting from a pre-qualified COTS power platform allows us to modify output voltage rails, connector configurations, mounting brackets, and EMI filtering without restarting full qualification campaigns. This dramatically cuts NRE expenses and shortens delivery schedules.

We provide comprehensive lifecycle support for military and aerospace programs that span decades. Our engineering team monitors component lifecycles proactive and designs form-fit-function replacements to ensure long-term availability without requiring system-level redesigns.
