Overview
The DC UPS modules supplement 24 V SITOP power supply units for interruption-free rated
currents of up to 40 A from SITOP BAT1600 and SITOP UPS1100 battery modules, which are
based on maintenance-free lead-gel or LiFePO4 batteries. With its integrated electronics,
SITOP UPS1600 automatically detects the battery type and charges it with the optimum
temperature-controlled charging characteristic curve. The intelligent battery management
monitors all relevant data, also for parallel-connected battery modules. The battery status and
various actual values, for example voltage and current, are output via the Ethernet/PROFINET
and USB interfaces. Thanks to the integrated web server, remote diagnosis is also possible.
The low profile SITOP UPS1600 DC-UPS module provides a dynamic overload behavior, e.g. to
switch on industrial PCs. The high charge current quickly restores the buffer readiness after a
supply system failure. And for the deployment in stand-alone operation, the UPS can be
activated from the battery for missing supply system voltage, e.g. to start the generators.
The key benefits of the product include:
• Compact SITOP UPS1600 24 V/10 A, 20 A and 40 A DC-UPS modules with digital
inputs/outputs, optional with USB or two port Ethernet/PROFINET interfaces
