APA Plug-in Hybrid Ground Power Units

ElectroAir's hybrid GPU category — smart dual-source units delivering both 28.5 VDC and 400 Hz AC from a combination of a diesel engine plus integrated battery, with an optional plug-in (utility power) capability. Where mains/utility power is available the unit runs from the grid, cutting fuel consumption, engine running hours, local emissions and noise; the diesel engine provides full flexibility off-grid. The category development is supported by Airbus Helicopters. Hybrid models in the range include the APA-65 (EAR-600/EACR-45-600) hybrid GPU, APA-100 (plug-in hybrid option), APA-110 trailer-mounted unit and the Hybrid Rectifier Unit APA-10. The APA-100 explicitly offers an optional plug-in hybrid utility-power function while combining 90 kVA 400 Hz AC + 800 A 28.5 VDC in one mobile Deutz Stage 5 unit.
