Rotary Diesel UPS
The Hitzinger Dynamic Rotary Diesel UPS, uninterruptible 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 centers and healthcare applications.
Maximum availability and reliability
The reliability of Hitzinger Rotary Diesel UPS systems is the result of product philosophy with the use of a minimum number of system components having an optimum quality standard.
DDUPS COUPLING CHOKE
Within a Diesel UPS system the coupling choke connects the input grid supply with the UPS high quality output supply. It allows large voltage differences between both AC systems by means of reactive currents for any direction, independent of the active power flow. The special design of the choke provides a high degree of de-coupling in both directions between the input and the output. The Coupling choke provides: Static and transient voltage decoupling of the input mains and the UPS bus -Harmonic filtering -Input load levelling irrespective of 100 % unbalanced output load -Input Power factor correction > 0.98 from 0 - 100 % load at nominal voltage. In the event of input short circuit the current flow towards the grid network is limited by the choke to < 200 % I nominal until the input is disconnected. During this transient the current feed back to the mains is wholly reactive, ensuring all the kinetic stored energy can be fully utilised for the critical load.
