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
