R Power


Rotating 400 Hz converters are still very popular among connoisseurs on the market and are characterized by their extremely robust, overloading, maintenance-free and long-lasting design without any network effects.

Decentralized rotating 400 Hz converters can be set up close to the point of use in order to provide the respective aircraft with the shortest route safely and reliably. Aircraft operators, maintenance companies, hangers and airports have been trusting the proven quality of R POWER for decades.

Technical Highlights

The R POWER is characterized by robustness, longevity, optimized efficiency with compact dimensions and lowest noise emission. Low maintenance, simple servicing and operation complete the image of a unit successfully established over decades in the market. We guarantee optimal and reliable performance for special applications.

Rugged operating conditions
Thanks to a generous conceptual design and an ingenious design, R POWER reliably and without any restrictions makes available the specified performance at any time without restriction.

Service life> 25 years – highest reliability
Due to the proven and robust technology, the R POWER can be used without any problems for more than 25 years.

Reliability: MTBF> 50,000 h

Increased Efficiency
Because of the high efficiency of the engine and the generator, aircraft can be optimally supplied in an optimal manner.

Maximum serviceability
The modular switchgear simplifies all service work. A generously designed sound and / or weather protection system ensures an optimal service and maintenance access.

Safe operation
Comprehensive protection and monitoring by microprocessor control.

Simplified operation
The touch panel of the control unit is characterized by intuitive user guidance. It is also well-readable in high solar irradiation, dust and water tightness, as well as for the most adverse operating conditions. The resistive touch screen can easily be operated with gloves. In an error recorder, all events are logged.
