The requirement for power supply reliability is growing, due to the increasing application of information
and data carrier systems, text processing, automated production processes and complex data networks.
Irregularities due to loading of the public power supply by major users, peak-time use or by lightning strikes
cannot be avoided.
The result is:
Mains voltage breaks, spikes and transients.
Static UPS’s are being installed increasingly for loads that require AC voltages unaffected by interference
on the mains e.g.
• Data processing installations
• Process control computers
• Air safety installations
• Signalling, alarm systems
• Telecommunication systems
• Power- and Substations
Due to the use of IGBT transistors of the newest technology in the rectifier and in the inverter, the new TBUPS
800 range fulfills the highest reliabilty for power supplies and is very economical.
This results in an input power factor of = 0,99 and an input distortion factor of < 5 %. The exceptional characteristics of this inverter in the TBUPS 800 series results in very small dynamic voltage deviations even in the case of one hundred percent load changes
