Technical highlights

From the installation to the first start and permanent application, S POWER sets itself apart with its reliability and its simple operation. Optimal voltage quality at maxium service security and serviceability power. Guaranteed power for all types of aircraft.

Maximum Efficiency

The intelligent distribution of the individual stacks and the configuration of the S POWER guarantees very high efficiency during turn-down for all load requirements.

Highest Reliability

The plug&play system featured by stack technology enables individual stacks to be easily serviced. In case a stack fails, redundant operation is possible.

Best Serviceability

Remote maintenance enables every important operational state to be displayed and parametrized, and regulation of ventilation and temperature monitoring may also be adjusted. Exact error notification shortens maintenance periods and optimizes service.

Userfriendly Controls

The touch panel on the controller features intuitive user guidance. The display is easy to read in sunny conditions, it is dust and waterproof, and it is suitable for the most adverse airfield conditions. It may even be operated by gloved hands.
