J. Schneider AC C-TEC 2403-1

J. Schneider AC C-TEC 2403-1, Capacitor buffered Power Supply. The buffered DC power supply of the AC C–TEC series includes ultra-capacitors as energy storage inside the housing. During normal operation this capacitor is charged from AC-mains. The connected DC consumers are supplied as well from AC mains. In case of an interruption of the AC supply, the energy of the ultra-capacitor is realesed regulated. With a dc/dc converter the load is supplied from the capacitor until it is discharged. The backup time depends on the state of charge of the capacitor and the discharge current.

The power supply has the following characteristics:

Maintenance-free because of long-life ultra-capacitors
Mikrocontroller based charging and discharging oft he ultra-capacitors
Control of operation and status of charge with potential-free contacts and LED
Capacity extension possible with external capacitor extension modules
