The THOR RM is currently the most compact online double conversion UPS system and can be used in the smallest space. It is suitable for parallel redundant operation and can be extended to extremely long autonomy times using external battery packs.

With its rack design, it can be used as a plug-in device to set up an individually designed UPS system in all 19-inch network cabinets.

With an efficiency of over 95% in normal operation, it is one of the most effective and economical 3-phase UPS systems on the market and is therefore ideally suited to saving money.
