Starting and supply of aircraft with 28 V onboard power supply

The ground power units of the HEIDEN 1100 series are used for mobile supply of consumers with 24…28 VDC Supply voltages, such as industrial trucks, military equipment, motor vehicles, mobile and stationary engines, aircraft and others consumers with a high current demand. These power supply units provide energy for starting aircraft and to conserve the on-board battery during maintenance. They supply large and undisturbed DC currents.

Worldwide use

The type HEIDEN 1100-128 can be used worldwide for all common 3-phase public grids, as it contains a reversible mains voltage adjustment for sine and delta voltages from 190-200-210 and current voltages 380-400-420 VAC with 50 / 60 Hz. Only the power cables and a few other components must be ordered according to the respective mains voltage. The conversion for operation on American or European grids can also be done by the customer at a later date.

Mains independent GPU types are our 1101 and our 1105.

For maintenance equipment with 115 / 230 V devices

Measuring instruments for diagnostics and tools for maintenance equipment directly on the aircraft or helicopter, which has a 115 VAC or 230 VAC mains voltage can be supplied via the service sockets (SchuKo socket type F or USA socket type B). This supply is galvanically isolated from the mains supply.

For harsh environmental conditions

These ground-power supplies are designed for worldwide use and can therefore be used under harsh climatic conditions. An enclosure made of stainless V2A steel with powder coating with special exhauster openings and appropriate rain protection guarantee a wide operating temperature range.
