Product Details


The DC UPS module can be combined with at least one 24 V battery module and a SITOP power supply unit. This combination means that longer power failures can be bridged without any interruption. Even if a greater buffering current is required, the DC UPS with maintenance free lead battery provides optimum safety. It spans power failures up to several hours long and delivers up to 40 A.

Features and Benefits

• 24 V buffering for a few hours for continuing processes • Maintenance free battery modules from 1.2 Ah to 12 Ah
• High reliability and availability due to monitoring of the operational readiness, battery feeder, ageing and charging status
• Long operating life of loads and batteries due to integrated battery management
• Settings by DIP switches: Battery connection threshold, end-of-charge voltage, charging current, bridging time
• SW tool, free of charge, for easy configuring and integrating in PC-based systems

Product Application Information

These battery modules can be connected in parallel and bridge power failures for a few hours. The bridging enables processes or parts of them to be continued, measured values to be recorded without interruption and communication to be maintained. High-performance industrial PCs that have to be shut down also have higher energy demands. Especially if a large panel remains operated during the shutdown. The DC UPS is used in machine tool production, textile industry, production lines, bottling plants or also for the obstacle lights of wind power plants.
