Starting and supply of 28 V DC Aircraft

The independent 1101 ground power supply reliably supplies energy for starting and maintenance of airplanes to save the onboard accumulator. The 1101 delivers large and undisturbed DC currents.

Mobile current supply

The GPU 1101 is used for the mobile supply of consumers with high current demand and 24…29 VDC supply voltages such as industrial trucks, military equipment, motors, as well as a power supply and charging device.

Our Trolley GPU 1105 is an even more compact, mains-independent ground power unit.

Internal energy storage

The energy required for starting or supply is taken from novel, internal Lithium Iron Phosphate high power batteries with 100 Ah, which are charged with the integrated charger.

Energy for > 5 starts

In the standard configuration, more than five starting procedures of common helicopters (EC135 and H145) can be performed without recharging. These units thus surpass all alternatives available on the market so far!

Shortest charging time

The charging time of an energy storage device depends mainly on the discharge state, the permissible charge current and the power capability/intelligence of the charger. The energy required for a battery that is discharged to 30 % is < 60 minutes. The processor-controlled charging is carried out with up to 3,000 W and enables very short charging times.

High continuous current

For service or maintenance purposes a continuous current supply is usually required. If the energy required for this is not to be taken or only partially taken from the batteries, the device must be connected to the public AC grid. The built-in charger charges the energy storage with up to 120 A. If more than this charging current is continuously drawn from the device, the energy storage device is discharged with the difference between the discharge and charging current. If less current is continuously drawn, the energy storage device is charged simultaneously.
