R POWER decentral

Rotary 400 Hz converters are continuing to experience exceptional market demand, driven in particular by the power connoisseur. These units are characterised by their extremely robust, overload-resistant, maintenance-free and highly durable construction with no form of grid perturbation.

Decentralised rotary 400 Hz converters can be set up close to the point of use to supply aircraft safely and reliably at the shortest distance possible. Aircraft constructors, maintenance contractors, hangar operators and airports have been putting their trust in the proven quality of R POWER for decades.

Technical highlights

The R POWER is characterised by robustness, longevity, optimised efficiency with compact dimensions and the lowest noise emissions. Low maintenance and extremely easy servicing and operation complete the profile of a unit that has been successfully established on the market for decades. We guarantee you optimum and reliable power for special applications.

Arduous operating conditions
Thanks to a generous conceptual specification and an ingenious design, the R POWER delivers the specified power reliably, without limitation, anytime.

Service life >25 years – unrivalled reliability
With proven and robust engineering, the R POWER offers troublefree intensive and unlimited use for more than 25 years.

Reliability: MTBF >50,000 hours

Increased efficiency
Thanks to the high efficiency of the engine and alternator, aircraft can be supplied as economically as possible.

Maximum serviceability
The modular arrangement of the switchgear simplifies all service work. A large-size soundproofing and weather-protected enclosure provides optimum access for servicing and maintenance.

Safe operation
Comprehensive protection and monitoring by microprocessor controller.

Simplified user operation
The touchpanel of the control station offers intuitive user navigation. Easy to read even in strong sunlight, it is also dust- and water-tight and suitable for use in the most adverse conditions. The resistive touchscreen is straightforward to use even when gloves are worn. A fault recorder logs all events.
