Sinepower SINEGPU 30–90 kVA Solid-State 400 Hz Ground Power Unit
Solid-state 400 Hz GPU, 30/45/60/90 kVA, with NBPT and automatic voltage compensation.
Solid-state 400 Hz ground power unit for aircraft on stand, available in 30, 45, 60 and 90 kVA. Delivers 3-phase 200 V / 400 Hz at ±1% with crystal-controlled frequency stability (±0.01%), 90–95% overall efficiency, unity-power-factor IGBT rectifier input (THDi <2% at full load), and 4-quadrant operation. Supports no-break power transfer (NBPT) for uninterrupted switching between sources at the aircraft, with automatic load-dependent or remote-feedback voltage compensation. Static regulation ±1% across 0–100% load; dynamic recovery to 1% within ~20 ms; overload 120% for 600 s, 150% for 60 s, 200% for a few seconds. Built for harsh aprons: IP55 enclosure, C5-M coating, -40 to +40 °C, up to 2000 m, ~750×750×1250 mm cabinet.
