SINE GPU | 400 Hz Solid State GPU | 30 kVA - 180 kVA

Our Aviation GPU (solid state ground power units) are very efficient, easy to operate and maintain. They use double conversion technology with an integrated inverter output transformer to ensure galvanic isolation of the load.

Technical specification

Input	• 4-quadrant operation (better system response and safer operation for NBPT). • Low input harmonics (<1.5% THDi), to meet the strictest regulations at any load.
Technology	High frequency IGBT technology (rectifier and inverter) to ensure a sinewave input current with low input harmonics (THD‹1.5%) and unit power factor (PF=1). This is ideal for military applications as we guarantee minimal impact on the power grid or other upstream power sources. No Break Power Transfer compatibility (NBPT).
Options	Our Aviation GPU can support AC and Combi power output simultaneously, as long as the total load power does not exceed the power of the unit itself. Available ranges are: 1) AC • 30 kVA - 90 kVA (400Hz Unit) • 120 kVA (400Hz Unit) • 180 kVA (400Hz Unit) 2) Combi: • 30 kVA - 90 kVA Combi (400Hz Unit + 28VDC) • 120 kVA Combi (400Hz Unit + 28VDC) • 180 kVA Combi (400Hz Unit + 28VDC)
Output	An output of 200V 3 phase 400Hz to the aircraft through single or dual output. Can be connected to a standard 380V to 415V 3 phase 50Hz mains or other.
Efficiency	Our GPUs are highly efficient - up to 95% efficiency.
