2.1 Device description
2.1.1 SITOP UPS1600
The SITOP UPS1600 10 A, 20 A and 40 A are built-in devices of the SITOP series for mounting
on TH35-15/7.5 DIN rails (EN 60715). When installing SITOP UPS1600 devices, SITOP
BAT1600 and SITOP UPS1100 battery modules, the relevant DIN/VDE regulations or country-
specific regulations (e.g. VDE 0510 Part 2 / EN 50272-2) must be carefully complied with.
See Section Installation (Page 211)
In combination with SITOP BAT1600 and SITOP UPS1100 battery modules, they are used to
buffer the load current from the 24 V load power supplies of the SITOP series.
With their high dynamic overload capability up to the 300 % rated current for 30 ms or up to
the 150 % rated current for 5 s per minute, they are suitable for applications with
programmable logic controllers (PLCs) and industrial PCs, as they permit high switch-on
currents even in buffer mode.
The input of the SITOP UPS1600 DC-UPS module must be connected with the output of the
supplying 24 V DC power supply unit. The SITOP BAT1600 and SITOP UPS1100 battery
modules are connected to the BAT terminals. The loads to be buffered are supplied via the
output of the SITOP UPS1600 DC-UPS module with the voltage connected at the input.
The Energy Storage Link is an additional two-wire connection between the SITOP UPS1600
basic unit and the coded SITOP BAT1600 and SITOP UPS1100 battery modules. Furthermore,
the basic unit detects and manages as many as six battery modules and selects the optimum,
temperature-controlled charging characteristic curve. The latter provides the basis for the
long service life of the battery modules. Energy Storage Link also monitors the operational
readiness as well as the supply cables (wire breakage) and the charge state (voltage, current,
residual capacity) of the batteries.
Battery modules from other series and manufacturers can also be used; however, with
restricted diagnostic functions such as SoH (state-of-health) and without the temperature-
controlled charging function. To ensure optimum utilization, battery parameters must be
adapted in the HW configuration.
In the event of failure of the 24 V DC supply voltage or voltage dip below the set switch-in
threshold, the loads are supplied by switching over to the battery module. Buffering is
realized until the line supply returns or until the buffer time, set using the rotary coding
switch, has expired. If the buffer time has been set to MAX, then shutdown is realized when
the exhaustive discharge threshold is reached.
Using the output voltage interrupt function you can select whether the output voltage is
interrupted once the set buffer time expires if, in the meantime, the input voltage returns.
For devices without interface, the interruption lasts 5 s. For devices with interface, the
interruption duration can be adjusted.
