CE, UL/cUL. SITOP DC UPS. The DC UPS module can be combined with at least one 24V battery module and a SITOP power supply. This combination allows for longer power outages to be bridged without interruption. Even with higher buffer currents, the DC UPS with maintenance-free lead-acid battery provides optimal safety. It bridges power outages of several hours and delivers up to 40 A.

Features and benefits:

  • Several hours of 24V buffering for continuous operations.
  • Maintenance-free battery modules from 1.2 to 12 Ah.
  • High reliability and availability through monitoring of operational readiness, battery supply, wear, and charge status.
  • Long lifespan of loads and batteries through integrated battery management.
  • Settings via DIP switch: battery connection threshold, charge termination voltage, charge current, bridging time.
  • Free software tool for easy configuration and integration into PC-based systems.

Product application: These modules can be connected in parallel and bridge power outages for several hours. This bridging allows processes or parts of them to continue, measurements to be recorded without interruption, and communication to be maintained. High-performance industrial PCs that need to be shut down also have a higher energy demand, especially when a large panel continues to operate during the shutdown. The DC UPS is used in the manufacturing of machine tools, in the textile industry, for production lines, filling systems, or for obstacle lights of wind turbines.
