Static Inverter 28VDC → 115VAC / 400Hz 28VDC → 400Hz / 3-Phase
A 500–1200VA true-sinewave static inverter supplying aircraft-standard 115VAC, 400Hz avionics power from a 28VDC bus, qualified to FAA TSO-C73 / EASA ETSO-C73. Low RDS(on) MOSFETs and synchronous rectification deliver 90% efficiency, permitting a smaller heatsink and single-fan cooling at 6.25 lb max — with inrush, OV/UV, and over-frequency protection beyond typical competitive coverage.
A 3-phase, 400Hz static inverter variant built on the same 28VDC-bus platform and enclosure as the single-phase unit, for applications requiring 3-phase avionics power. Full electrical, connector, and weight specifications are pending release — contact us for current program status.
One rugged inverter unit
A single sealed housing converts 28VDC bus power into stable 115VAC, 400Hz output — the aircraft-standard avionics frequency — with no external conversion stages to integrate. Higher efficiency permits a smaller heatsink and single-fan cooling at 6.25 lb max.
The same sealed enclosure platform is being adapted to deliver 3-phase, 400Hz output for platforms requiring 3-phase avionics power. Electrical and mechanical specifications are pending qualification.
Why it outperforms
Where it fits
The Static Inverter's 28VDC input, single-phase 115VAC/400Hz output — the standard avionics bus frequency — and TSO-C73 / ETSO-C73 qualification suit it for forward-fit and retrofit installations across a broad range of 28VDC-bus platforms.
The Static Inverter's 28VDC input and 400Hz output — the standard avionics bus frequency — suit the 3-phase variant for the same broad range of 28VDC-bus platforms as the single-phase unit, pending completion of qualification testing.
