SITOP add-on modules for reliable 24 V DC even when the
power fails – Overview of the DC UPS systems
SITOP DC-USV
DC UPS module with maintenance-free
lead-acid batteries as the energy store.
Bridging of power failures for more than
one hour.
Selection criteria:
24 V supply sustained over long period, to
continue with running process, for example.
High load current to 40 A
SITOP UPS500

layer capacitors. Bridging of power
failures for minutes.
Selection criteria:
Data backup and powering down of
applications in the minute range.
Completely maintenance-free
High ambient temperatures of up to 60°C
No ventilation required because no gas is
emitted
Distributed use without control cabinet
Buffer module
Add-on module with electrolytic
capacitors for bridging brief power
failures. Can be combined with
SITOP modular.
Selection criteria:
Low-cost protection against power failures
of up to 3 seconds maximum
Support of the power supply unit when the
demand for current is briefly increased
High load current up to 40 A
Alternative to AC power supply: AC UPS from Masterguard, www.masterguard.de

Safe shutdown
Running applications and the operating system are saved
WinAC backs up the retentive data and shuts down for Windows XP, XP embedded and
Vista operating systems
The time between the power failing and shutdown of the PC can be set simply in the
software tool
After shutdown of the PC, the UPS can be shut down after a definable time
Maintenance of energy reserves
Integration of your own applications possible
For example, customized shutdown programs
Software for backlight shutoff for the Panel PCs 477B, 677B and IPC477C extends
the buffer time or enables use of a smaller energy store
The software is currently only available for Windows XP and can be obtained via the
SIMATIC Hotline

Correct restart of PCs
Problem:
If the PC is shut down following a power failure and the 24V is
maintained by the UPS, the PC can normally only be switched on again
by switching the 24 V DC supply or the PC off and on again.
Solution:
A brief interruption (approximately 5 s) of the 24 V DC supply voltage
can be set in the DC UPS, resulting in a restart of the PC. The
interruption only takes place after shutdown of the PC and if the mains
voltage is available

How is a system configured?
1.The customer selects the PC, the I/O devices and the application software
2.Calculation of the making current and the maximum operating current
- by means of current measurement
- or from the data sheets, if available
3.Ambient temperature?
4.Measurement of the time the system requires to save the relevant data, close
applications, and shut down
5.Selection of the power supply unit according to rated current (including
charging current for UPS) and max. peak current
6.Calculation of energy requirements
7.Selection of the DC UPS according to max. operating current, ambient
temperature and energy store
8.Note: After switching on, the UPS is not available while the energy store is
charging
