C POWER coupled with flywheel

Inefficient power supply networks and networks with short interruptions or above-average pulse loads require reliable quality and safety. C POWER stabilisation converters guarantee clean, independent output voltage and frequency stability for an extremely high level of supply quality and security of supply.

C POWER coupled with flywheel

Coupled systems are recommended for maximum power and special and medium voltages. If required, the engine and the alternator can be given resilient mountings in the form of vibration dampers. In order for the necessary energy to be made available in the event of brief interruptions or pulse loads, a flywheel is fitted to the shaft end of the alternator.

Technical highlights

The C POWER stands out thanks to its security of supply, robustness, longevity, optimised level of efficiency and, finally, thanks to the customised application for the customer.
Low maintenance and extremely easy servicing and operation complete the profile of an optimised unit that has been successfully established on the market for decades. We guarantee you optimum and reliable power for special applications, even in weaker supply networks.

Weak supply networks
Thanks to a special tailored design, calculation and testing, the C POWER delivers the specified power reliably, without limitation, any time, even in the event of short network interruptions of up to 3 seconds.

Pulse loads
Thanks to the precise and generous design of the flywheel, pulse loads can be tackled easily and securely.

Service life >25 years – unrivalled reliability
With proven and robust engineering, the C 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, a secure network supply can be guaranteed with minimal losses.

Maximum serviceability
The modular arrangement of the switchgear simplifies all service work.

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.
