R POWER 400Hz centralised rotary converter

Our 400Hz centralised rotary converter systems for Airport ground power, have benefited from 65years of alternator design, today, Hitzinger are proud to offer one of the most reliable and energy efficient rotary converters on the market. The Hitzinger 400Hz centralised rotary converter can be supplied as part of a larger distribution ring (Together with line-drop compensation) with multiple outputs feeding several connections simultaneously and can be synchronised with existing systems in order to meet increased load demand.

The Hitzinger centralised rotary converter are not only designed to be robust, but provide optimum efficiency for aircraft manufactures, contractors and airport operators.
