ENERTRONIC I: UPS System for Industrial Applications

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.
