Saver Plus series is an add-on to the Saver DSP Compact series with emergency backup devices up to 30kVA, three-phase input at one-phase output and expandability by external battery cabinets. They are intended for the use in open-plan offices or server cabinets. Highest fail-safe for the connected loads is guaranteed by the permanently working double converter. Simultaneously, the output voltage is stabilised, filtered and optimized to an almost perfect sine wave shape. This serves for achieving of an extended lifetime of sensitive and valuable loads. The internal batteries offer a long backup time, which still can be extended by external battery cabinets. A LCD panel and a standard communication interface allow simple use and remote control resp. monitoring. Various options ease up the integration into eventually existing systems.
