■ Overview
To combat prolonged mains failures the 24 V SITOP
power supply units can be upgraded into a DC-UPS
uninterruptible power supply.
SITOP offers two systems for this purpose:
• Battery modules as energy stores which provide a buffer in the
hours range
• Capacitors for 24 V buffering in the minutes range
The combination is 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.
For the SIMATIC IPC this means that all running applications, in-
cluding the operating system, can be shut down under stabi-
lized conditions.
The DC-UPS 24 V uninterruptible power supply with battery
modules is comprised of DC-UPS modules with 6 A, 15 A or
40 A output current and the battery modules 1.2 Ah, 3.2 Ah, 7 Ah
and 12 Ah (containing lead rechargeable batteries with corro-
sion-resistant lead-calcium high-performance grid plates and
glass fiber fleece) and 2.5 Ah (containing "high-temperature
rechargeable batteries" type Reinblei).
