Short description:
The DC- buffer module of the series C-TEC works with ultra-capacitors as energy storage inside the
housing. These capacitors are charge by a external regulated DC-power supply in normal operation.
In case of an interruption of the DC-power supply the energy of the capacitors is released. The load is
supplied by the buffer module till it is discharged. The back-up time depends on the state of charge of
the capacitors and on the discharge current.
