C POWER for test bay applications

The HITZINGER Rotary converter ‘C-Power’ is specifically designed to operate with a guaranteed level of stability, overload capacity, precision, reliability and network quality; all of which are fundamental for test bay applications. To accompany this high quality supply, the Hitzinger rotary converters benefit from the patented ACON display, a common feature of all our converter systems.

C-Power COUPLED Converter

Our coupled rotary converters systems are recommended to provide maximum power at your preferred voltage, with optional vibration dampers available for resilient mountings.

Technical highlights

The C POWER stands out thanks to its 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 a unit that has been successfully established on the market for decades. We guarantee you optimum and reliable power for special applications.

Arduous test bay conditions
Thanks to a tailored design, calculation, production and testing, C POWER delivers the specified power reliably, without limitation, anytime.

Service life >25 years – unrivalled reliabilityWith 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, test specimens can be supplied as economically as possible 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.
