Description
The SINE RPGPU is a compact, double-conversion ground power unit (GPU) designed for aviation use. It delivers isolated, stable 200 V three-phase 400 Hz AC power to aircraft, with high efficiency and low input harmonic distortion suitable for civil and military ground support operations.

Cable info

• Main input power from GPU to aircraft: 90 kVA
• Max. output current: 260 A
• Input power for cable drum operation: 50/60 Hz, 400/220 V
• Maximum input current for cable drum: 16 A

Input

• 4-quadrant operation for improved dynamic response and safer NBPT operation
• Low input harmonics (<1.5% THDi) to meet strict grid and aircraft requirements at any load

Technology

• High-frequency IGBT rectifier and inverter with double-conversion topology to ensure sinusoidal input current (THDi <1.5%) and unit power factor (PF = 1)
• Integrated inverter output transformer providing galvanic isolation of the load
• No Break Power Transfer (NBPT) compatible for seamless transfer scenarios
• Designed to minimize impact on upstream power sources; suitable for military-grade deployments

Options

• Supports AC output configurations provided total load does not exceed unit rating
• Available AC variants: 30 kVA to 90 kVA (400 Hz units)

Output

• 200 V, 3-phase, 400 Hz output to aircraft via single output
• Can be fed from standard mains 380–415 V, 3-phase, 50 Hz or other compatible supplies

Efficiency

• Up to 95% efficiency
