SINE33GPU – Ground Power Unit | 30KVA to 180KVA

SINEPOWER’s Ground Power Units range from 30 to 200 KVA solid-state Ground Power Supplies (mobile and fixed units) and The Standard  Range is: 30KVA; 45KVA; 60KVA, 90KVA, 120KVA and 180KVA.

SINE33GPU- Ground Power Units deliver an output of 200V 3 phase 400 Hz to the aircraft through a SINGLE or DUAL OUTPUT contactor and can be connected to a standard 380V to 415V 3 phase 50Hz mains or other.

SINE33GPU- Ground Power Units use High frequency IGBT Technology (Rectifier and inverter) to guarantee a sinewave input current with low THDi (THD‹1.5%) and unit power factor (PF=1), perfect for civil airports and military applications as we guarantee a minimum impact on the mains or other power sources upstream.  

SINE33GPU- Ground Power Units are highly reliable, very efficient and easy to operate and maintain. Our GPU (Ground Power Units) use double conversion technology with an integrated inverter output transformer to ensure galvanic isolation of the load.


SINEPOWER’s Ground Power COMBI Units can support AC and DC power output simultaneously as long as the total load power does not exceed the power of the unit.


SINEPOWER can supply special flexible, 400Hz cables with the control and signalling wires included.



SINEPOWER has obtained Full AENA certification:

AENA: Protocolo de pruebas en laboratorio oficial para la aceptación de convertidores estáticos de 400 Hz fijos de 90 kVA.
