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 standard mounting rails (EN 60715). When installing the
SITOP UPS1600 devices and SITOP UPS1100 battery modules, the relevant DIN/VDE
regulations or country-specific regulations (e.g. VDE 0510 Teil 2 / EN 50272-2) must be
carefully complied with.
See Section Installation (Page 149)
In combination with the 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 seconds per minute, they are suitable for applications with
programmable logic controllers (PLCs) and industrial PCs, because they permit high switch-
on currents even in buffer operation.
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 UPS1100 battery module is 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 new. This is an additional two-wire connection between the
SITOP UPS1600 base device and the coded SITOP UPS1100 battery modules.
Furthermore, the base device detects and manages as many as six battery modules and
selects the optimum, temperature-controlled charging characteristic curve. The latter
provides the basis for a long service life of the battery modules. The Energy Storage Link
also monitors the operational readiness as well as the supply cables (wire breakage) and the
charge state (voltage, current) of the rechargeable batteries.
The connection to the SITOP UPS1100 battery module is checked every 20 seconds (for
voltage, reverse polarity protection). A test with a defined load of the lead or LiFePo batteries
is also performed automatically every four hours (basic setting).
Battery modules of other type series and manufacturers can also be used, although with
limited diagnostic functions, such as the display of the charging current or the end-of-charge
voltage and without the possibility of temperature-controlled charging.
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 as to whether the output voltage is
interrupted once the set buffer time expires if, in the meantime, the input voltage returns.
