This back
ble 24 VDC power supplies for electronic modules in case the voltage tolerances mentioned in
our data sheets c
voltage transients could be:
-up capacitor module smoothes unsta-
annot be ensured. Reasons for
• Power interruptions (switching transients) on
primary side
• Overloads on secondary side
• Switching of inductive or capacitive loads
• The back-up capacitor module is connected
between the 24 V power supply and the electronic device to be protected.
Notic
e:
Using insuciently smoothed and unregulated
single-phase power supplies may lead to voltage
increases by the back-up capacitor module.
