SITOP Selection Tool –
find the appropriate power supply quickly and easily
With the SITOP Selection Tool, not only the DC supply can be
selected, but also the appropriate uninterruptible power supply
(DC UPS) with capacitor or battery technology.

SITOP
SITOP uninterruptible power supplies (DC UPS)
To combat prolonged mains failures the 24 V SITOP power supply units can be upgraded into a 24 V DC
uninterruptible power supply. SITOP offers two systems with different energy stores for this purpose:
• Capacitors for 24 V buffering in the minutes range
• Battery modules which provide a buffer in the hours range
The DC UPS systems are used for example in machine-tool building, in the textile industry, on all types of
production lines and filling plants, and in conjunction with 24 V industrial PCs. They prevent the negative
consequences which often result from mains failures.
SITOP DC UPS with capacitors
To bridge brief mains failures, 24 V SITOP power supply units can be expanded with a SITOP UPS500
uninterruptible DC power supply (DC UPS).
In PC-based automation solutions, the highly capacitive double-layer capacitors of the SITOP UPS500 supply
enough energy to safeguard operating and application data and close software applications in a defined manner.
Essential product features
• Buffering into the minutes range depending on the load current and DC UPS configuration
• Absolutely maintenance-free double-layer capacitors
• Short charging times
• IP65 variant for use outside the control cabinet
• USB interface for PC communication
SITOP UPS1600 with battery modules
By combining one SITOP UPS1600 DC UPS module with at least one UPS1100 battery module and a SITOP
power supply, longer power failures can be bridged absolutely free of interruptions.
Intelligent battery management automatically detects the UPS1100 energy storage device, and ensures optimum
temperature-controlled charging and continuous monitoring.
The compact DC UPS modules are overload-capable in order to supply e.g. the inrush current for industrial PCs.
They enable starting from the battery for stand-alone operation.
The DC UPS communicates openly through USB or Ethernet/PROFINET.
Via two Ethernet/PROFINET ports, it can be easily integrated into the PC or PLC world.
Complete integration in TIA offers user-friendly engineering in the TIA Portal and is supported by ready-to-use
function blocks for S7 user programs and WinCC faceplates for rapid visualization.
Use of the SITOP UPS manager also enables easy monitoring and configuration in PC systems, e.g. the shutting
down of several PCs in accordance with the master-slave principle. The integrated web server also allows remote
monitoring of the DC UPS.
Essential product features
• Compact SITOP UPS1600 DC UPS modules with digital inputs/outputs, USB interface or two Ethernet/PROFINET
interfaces
• SITOP UPS1100 battery modules with maintenance-free rechargeable lead-gel batteries
• High dynamic overload capability and high charging currents
