SITOP DC UPS uninterruptible power supplies
DC UPS with battery modules
SITOP DC UPS
■
Overview
By combining a DC UPS module with at least one 24 V battery
module and a SITOP power supply unit, longer power failures
can be bridged without any interruption. Even if a greater
buffering current is required, the DC UPS with maintenance-free
lead battery provides optimum safety. It spans power failures up
to several hours long and delivers up to 40 A.
■
Benefits
•
24 V buffering for a few hours for the purpose of continuing
processes
•
Maintenance-free battery modules from 1.2 to 12 Ah
•
High reliability and availability due to monitoring of the opera-
tional readiness, battery feeder, aging and charging status
•
Long operating life of loads and batteries due to integrated
battery management
•
Settings by means of DIP switches: Battery connection
threshold, end-of-charge voltage, charging current, bridging
time
•
SW tool, free of charge, for easy configuring and integrating
in PC-based systems
■
Application
These battery modules that can be connected in parallel bridge
power failures for a few hours. This enables processes or parts
of them to be continued, measured values to be recorded with-
out interruption and communication to be maintained. High-
performance industrial PCs that have to be shut down also have
somewhat higher energy demands. Especially if a large panel
continues to be operated during the shutdown. The DC UPS
is used, for example, in machine tool production, in the textile
industry, in all types of production lines, bottling plants or also for
the obstacle lights of wind power plants.
The serial or USB interface and a free software tool enable easy
communication with a PC.
Configuration with SITOP DC UPS and battery module: 24 V buffering
to maintain communication, signaling and sensor measured values.
To relieve the load on the UPS, the actuators are supplied directly from
the power supply unit.
