Supports cold start and enables temporary battery operation when mains power fails. Energy consumption meter displays usage in kilowatt-hours for energy-conscious users. Green operating mode is a patented feature where unused electrical components are switched off under good power supply conditions, achieving very high operational efficiency without compromising safety. High online efficiency reduces electricity costs and generates less waste heat. The intuitive LCD user interface provides easily readable information in multiple languages and supports on-site UPS configuration with user-friendly navigation buttons. The display shows the battery replacement date, facilitating long-term maintenance planning. A pre-installed network management card enables remote management of the UPS system immediately after commissioning. The single module has switchable outputs, allowing individual output groups for separate control via the UPS system for targeted rebooting of unresponsive systems, sequential switching on or off of systems, or shutting down non-critical loads. SmartSlot allows for upgrading your UPS with management cards that have individual functions. Battery charging with temperature compensation extends battery life by regulating the charging voltage according to the actual battery temperature. Availability notifications alert users of disconnected batteries and issue warnings when a battery is not available for power supply. The automatic restart feature powers up connected devices when mains power returns, and the automatic self-test conducts periodic battery self-tests for timely replacement of depleted batteries.
