GPU – Mobile Frequency Converters – 30KVA, 45KVA, 60KVA and 90KVA

RBC8000M Mobile GPU’s – Ground Power Unit / 30KVA, 45KVA, 60KVA and 90KVA

Our RBC8000M Mobile 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.

RBC8000M Mobile – Ground Power Units use High frequency IGBT Technology (Rectifier and inverter) to guarantee a sinewave input 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.  The RBC8000’s 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.

The Red Box RBC8000M units come supplied as standard with a 10m Input cable and a 10m output cable, with control and signalling wires and aircraft connector. Other cable lengths are available on request.
