Static Inverter28VDC → 230VAC / 50Hz

A 500–1200VA true-sinewave static inverter engineered for FAA TSO-C73 / EASA ETSO-C73 platforms requiring stable 230VAC, 50Hz power from a 28VDC bus. Low RDS(on) MOSFETs and synchronous rectification deliver 92% efficiency, permitting a smaller heatsink and single-fan cooling at 6 lb max — with inrush, OV/UV, and over-frequency protection beyond typical competitive coverage.

The Hardware

One rugged inverter unit

A single sealed housing converts 28VDC bus power into stable 230VAC, 50Hz output — no external conversion stages to integrate. Higher efficiency permits a smaller heatsink and single-fan cooling at 6 lb max.
