Aircraft Power Supplies & Avionics Power Units
START PAC® aircraft power supplies deliver immediate, limitless clean DC power for avionics testing, cockpit maintenance, and ground support operations — without running the engine. Available in 12V, 24V, and 28V configurations, output voltage is matched to the level an aircraft would see when running under generator power, protecting sensitive onboard systems from voltage irregularities. Connect to any AC wall socket and your cockpit has continuous, no-duty-cycle DC power for as long as you need. Onboard batteries stay charged, protected from deep discharge, and last significantly longer.
Please note:
START PAC® power supplies are designed for aircraft maintenance, avionics testing, and cockpit operations on the ground. They are NOT designed for engine starting or battery charging. If you need engine starting capability, see our Starting Units or Ground Power Units

FAQ
What is an aircraft power supply used for?
A START PAC® aircraft power supply delivers continuous DC power to the cockpit for ground-based maintenance and testing operations — without running the engine. Typical uses include GPS programming and updates, transponder and radio maintenance, ILS and instrument checks, FLIR and camera operation, searchlight and lighting tests, static instrument training, entertainment system testing, and cockpit lighting for exhibition or inspection purposes.
What voltage do I need — 12V, 24V, or 28V?
12V units (Model 53050M 12/14V) are suited to piston-engine and general aviation aircraft running 12V electrical systems. 24V and 28V units cover turbine aircraft, business jets, commercial aircraft, helicopters, and military platforms. The 28V output is set to match the voltage an aircraft sees when running under generator power, ensuring compatibility with sensitive avionics systems. If you are unsure which voltage your aircraft requires, call 844.901.9987 with your aircraft make and model.
What amperage output do I need?
Amperage depends on the load you need to power. 25A is sufficient for basic avionics checks and GPS programming. 50A covers full cockpit power for most maintenance tasks including radio, ILS, and instrument work. 300–400A is required for heavy loads such as searchlights, air conditioning systems, full cabin entertainment, and multi-system simultaneous operation. The START PAC® team can confirm the right amperage for your specific aircraft and maintenance requirements.
Can START PAC® power supplies start an engine or charge a battery?
No. START PAC® power supplies are designed exclusively for ground-based maintenance power — they deliver continuous, regulated DC power to cockpit systems. They are not designed for engine starting or battery charging. If you need engine starting capability, see the Starting Units range. For combination starting and maintenance power, see the Ground Power Units range.
Can these units be used for flight simulator and avionics module testing?
Yes. START PAC® power supplies are used for flight simulator cockpit power and avionics module testing in training and development environments. The clean, no-duty-cycle DC output at generator-matched voltage makes these units suitable for sensitive simulator electronics and avionics bench testing as well as aircraft ground support.
Are START PAC® power supplies available for military and aerospace OEM applications?
Yes. Military versions of the Model 53050M (12/14V) and Model 53025M (24/28V) are available for defense MRO and aerospace OEM applications. START PAC® is ISO 9001 certified and has supplied defense and government customers globally. Custom configurations — including specific voltage, amperage, and connector specifications — can be manufactured to meet exact platform requirements. Contact START PAC® directly for defense and OEM enquiries.
Do START PAC® power supplies work with any aircraft type?
Yes. The product range covers 12V, 24V, and 28V configurations, addressing the electrical systems used across piston-engine general aviation, turbine aircraft, business jets, commercial aircraft, helicopters, and military platforms. For aircraft with non-standard requirements, the START PAC® team can advise on custom configurations.
What does no-duty-cycle mean and why does it matter?
No-duty-cycle means the unit delivers continuous power without requiring rest periods between uses. Standard battery-based units need recovery time after periods of high load. A no-duty-cycle power supply can run a cockpit for hours without interruption — important for long maintenance sessions, avionics certification work, and multi-system testing where continuous, uninterrupted power is essential.
