High-Performance Power Simulation for Aerospace Engineering
Adaptive Power Systems provides advanced AC/DC power sources and programmable electronic load banks engineered specifically for military defense contractors, commercial aerospace manufacturers, maintenance depots, and avionics overhaul facilities worldwide.
400Hz & Wild Frequency AC Power Sources
Aerospace electrical architectures overwhelmingly rely on 400Hz AC power rather than standard 50Hz/60Hz commercial utility power. Operating at 400Hz significantly reduces the magnetic weight and size of onboard transformers and motors, directly contributing to payload efficiency and fuel savings.
Testing avionics during R&D, manufacturing assembly, and maintenance overhaul requires stable 400Hz frequency conversion from standard factory grid inputs. Adaptive Power Systems solid-state frequency converters supply precise 115Vac single-phase and 115Vac/208Vac three-phase output across fixed (400Hz) and variable frequency ranges (360Hz to 800Hz 'wild' frequency profiles used in modern commercial jetliners).
- • Output Frequencies: 400Hz fixed, 45Hz–500Hz, and 360Hz–800Hz wild frequency simulation.
- • Configurations: Compact benchtop units up to 150 kVA high-power cabinet systems.
- • Waveform Integrity: Low THD (<0.5%), pure sine wave output under harsh non-linear avionics loads.
High-Voltage 270Vdc & Traditional 28Vdc Aerospace Power Supplies
Modern military aircraft, naval vessels, and unmanned aerial vehicles (UAVs) increasingly utilize high-voltage DC distribution systems—such as 270Vdc—alongside conventional 14Vdc and 28Vdc onboard electrical buses. High-voltage DC minimizes cabling cross-section, reducing airframe weight while satisfying electrical loads from advanced flight controls, radar arrays, and defense electronics.
APS programmable DC sources deliver tightly regulated, low-noise DC output designed to withstand rapid transient load switching. Built-in voltage transient generator capabilities enable engineers to easily verify avionics compliance under voltage sags, surges, and momentary power interruptions defined in military power quality standards.
Programmable AC & DC Electronic Loads for Avionics Testing
Developing robust power conversion equipment—such as Transformer-Rectifier Units (TRUs), inverters, auxiliary power units (APUs), and flight-deck power supplies—requires heavy-duty load equipment capable of delivering flexible, repeatable stress profiles.
Adaptive Power Systems offers comprehensive AC and DC load banks engineered for defense testing. Key operational capabilities include:
AC Electronic Loads
Deliver programmable power factor control (leading and lagging), crest factor adjustments, and dynamic transient switching for testing 400Hz generators and airborne AC-AC converters.
DC Electronic Loads
Deliver Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR), and Constant Power (CP) operational modes up to 1000Vdc and multi-hundred-kilowatt dynamic parallel setups.
