What is eBoost?

e = high efficiency (up to 99%)
Boost = fast power transfer (<2ms)

Technology breakthroughs

Up to 99% UPS efficiency
Compliant to ITI (CBEMA) curve during undervoltage events
Up to 4.8 MW UPS capacity using Redundant Parallel Architecture (RPA)
Magnetizing the output transformer ensures a < 2ms transfer time
Static bypass inductor for filtering utility power
Battery trickle charge in eBoost operating mode

eBoost™ – guaranteed higher UPS efficiency

Double conversion

During traditional operation the UPS runs in double conversion mode. Both the rectifier and the inverter are continuously operating, resulting in an efficiency of 92-94%.

eBoost single module

During eBoost operation the load is supplied directly by the mains, via the static bypass circuit. This provides an efficiency up to 99%. In case the mains voltage is out of tolerance, the UPS will immediately transfer the load to the inverter in < 2ms. The < 2ms is achieved by our patented* technology to magnetize the output transformer. The output transformer provides galvanic isolation between inverter and load. The static bypass inductor filters the input AC power during eBoost operational mode.

eBoost in Redundant Parallel Architecture

eBoost in RPA uses high speed communication and fast digital signal processors (DSP) to parallel up to 6 UPS modules. eBoost in RPA provides up to 4.8 MW capacity and up to 99% efficiency while maintaining <2ms transfer time, compliant to the ITI (CBEMA) curve.
