24 V DC Uninterruptible Power Supply
High-performance, communicative and integrated in TIA
If a power failure occurs, not only does the AC power go
out but also the 24 V DC supply and thus the complete
automation system as well. Costly downtimes and undefined system states can be the result. DC uninterruptible
power supplies prevent this scenario by providing reliable backup of the DC voltage for hours while also providing diagnostics and system integration. The new
SITOP UPS1600 offers even more possibilities for system
integration with comprehensive functions and open communication via USB or Ethernet/PROFINET – the first DC
UPS with these interfaces, allowing it to fully integrate
into projects in TIA Portal.
The DC UPS modules complement 24 V DC power supplies
from SITOP for uninterrupted rated currents up to 20 A from
the UPS1100 battery modules based on maintenance-free
gel cell batteries. Via the integrated electronics, the
UPS1600 automatically detects the type of battery and
charges it at the optimal, temperature-controlled charging
characteristics. The intelligent battery management system
monitors all relevant data, including battery modules connected in parallel. The battery status and various values,
such as the ­voltage, current or residual capacity, are output
via the ­Ethernet/PROFINET interface. Even remote diagnostics by means of a secure network is possible thanks to an
integrated web server. The device status of the UPS1600
along with the network connection can be easily monitored
in the SINEMA Server network management software.
The slim UPS1600 DC UPS module features dynamic overload response, which can be used to activate industrial PCs,
for example. The high charging current quickly restores the
buffering capacity following a power failure. For use in
stand-alone mode, the UPS can be activated from the
­battery, for example, to start generators.

SITOP UPS1600 – the first open...
Whether open or system-integrated, the communicative DC UPS can be integrated into any automation solution. Fully
flexible data communication is performed via USB or Industrial Ethernet/Profinet. Special configuration and visualization software makes it easy to integrate the DC UPS in both PC and PLC based systems. This means you benefit from the
high performance of the SITOP UPS1600 in any case.

SITOP UPS1600 in PC-based automation system:
Configuration and monitoring takes place via
SITOP UPS Manager software. If a power failure occurs,
the 24 V DC buffer and the integration of the DC UPS in
Industrial Ethernet enable controlled shutdown of
multiple PCs in master-slave mode.
Remote monitoring via the web server:
The integrated web server provides access to all
relevant power supply data, of course, only with
­appropriate user credentials.
Configuration and monitoring with the
SITOP UPS Manager:
The free software tool supports easy configuration
of the UPS in the PC system and also visualization of a
wide variety of states of the UPS, even in the form of
trend charts.

SITOP UPS1600 in Totally Integrated Automation:
Engineering takes place via the TIA Portal.
If a power failure occurs, the 24V DC buffer and the integration of the DC UPS in PROFINET enables the PLCs to be
brought to a defined state independent of one another.
Function blocks for SIMATIC S7-300 and 1500 (400 and
1200 available soon) are available for this purpose. The
comprehensive diagnostic data of the power supply can
be visualized by various devices, for example, via UPS
Engineering in the TIA Portal:
The UPS configuration is also extremely user-friendly,
because the configuration data of UPS1600 and UPS1100
are stored in the TIA Portal.
Advantages of the SITOP UPS1600
through system integration
•Full integration in TIA saves time and money
in planning and operation
•Convenient engineering of SITOP DC UPS in the
TIA Portal
•Fast selection of products and network integration in
•Comprehensive device configuration
