SITOP DC UPS uninterruptible power supplies
DC UPS with capacitors
■
Overview
SITOP 24V power supplies can be expanded with a SITOP
UPS500 uninterruptible DC power supply (DC UPS) for bridging
short-term power failures in the order of minutes. For PC-based
automation solutions, the high-capacity double-layer capacitors
of the SITOP UPS500 supply enough energy to back up the
operation and application data and to shut down software appli-
cations in a defined manner. You can increase the buffer times
using SITOP PSU501S expansion modules (up to 3).
The IP65 version SITOP UPS500P in long metal housing is
ideally suited to distributed use.
■
Benefits
•
24 V buffering for a few minutes to allow data to be backed up
and applications to be closed.
•
Absolutely maintenance-free
•
Long lifetime, even at high temperatures
•
High ambient temperatures up to +60 °C
•
Short charging times
•
No ventilation is required since no gas is emitted
•
Distributed applications possible without control cabinet
•
Software tool, free of charge, for easy configuring and
integrating in PC-based systems
■
Application
The high-capacitance double-layer capacitors bridge power
failures for a few minutes. The time is normally sufficient, for ex-
ample, for the safe shutdown of PC-based automation systems.
The USB interface and a free software tool enable easy commu-
nication with the PC.
The capacitors have an extremely long life even at high tempera-
ture, and can be used at ambient temperatures of up to 60 °C.
SITOP UPS500P in IP65 degree of protection can also be in-
stalled outside the control cabinet in a distributed configuration.
Configuration with SITOP UPS500S:
24 V buffering for backing up process data and performing a controlled
shutdown of a PC. To relieve the load on the UPS, the actuators are
supplied directly from the power supply unit.
