    400Hz Ground Power Supplies
  • UPS Systems

    ‘Variations in the supply of power, such as Voltage peaks from the grid and sags or total cut offs, may have serious effects which could lead to production breakdown, data loss and loss of earnings.

    The reliability and quality of the public power supply is sometimes not sufficient for the growing number of consumers. Hitzinger’s Rotary Diesel UPS offers the best in quality and reliability.

    The Hitzinger Dynamic Rotary Diesel UPS, uninterruptable power supplies, system comprises of four major components: diesel engine, generator, kinetic energy storage module and coupling choke.

    The kinetic energy module, generator and coupling choke work together to provide power conditioning and ride through energy for the UPS system, whilst the diesel engine provides the long-term back up for a mains failure.

    These systems provide extremely high availability and reliability in case of mains failure and high efficiency during stand-by operation because of carefully design and individual components selection.

    Mains failure of as a little as a millisecond will cause serious consequences and expensive production outage and subsequent mistake costs in a wide range of industrial, electronical, Airports, computer  centres  and  healthcare  applications.’
