Artikelnummer:  69004-98CBS2402100

The buffered DC power supply of the CBS series has an internal ultracapacitor as energy storage. In normal operation (input voltage available) the power pack supplies the connected DC loads and keeps the capacitor charged. If the input voltage is interrupted, the energy of the ultracapacitor is released in a controlled manner. The load is fed by the capacitor via a DC / DC converter until it is discharged. The buffer time depends on the state of charge of the capacitor and the discharge current.

The CBS capacitor-buffered power supply units are ideal as UPS for short failures or the transmission of the last message, e.g. in telecontrol systems or networked fault indicators with telecontrol interface, e.g. in transformer stations.
