Capacitor buffered power supply manufacturer: J. Schneider Elektrotechnik GmbH type : C-TEC 2408-20 Art.-No. : 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.
