C POWER coupled with flywheel

With growing concern over the quality of incoming mains power, the HITZINGER converters for grid stabilisation provide a guaranteed clean source of power. This conditioned voltage and frequency is maintained within tolerance on the consumer and provides the client with a very high security of supply.

C-Power COUPLED with flywheel

Our coupled systems are recommended to provide maximum power at your preferred voltage, with optional vibration dampers available for resilient mountings. In case of mains interruptions, the C-Power converter with flywheel, located on the alternator shaft, will provide the necessary ride-thru energy when needed

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.
