J. Schneider C-TEC 2403-1of Capacitor-buffered Power Supply, The buffered DC power supply of the C–TEC of series is an open frame device, a board, which includes ultra-capacitors as energy storage inside the housing. During normal operation this capacitor is charged from the system voltage (Ue).
The connected DC consumers are supplied as well from the system voltage. In case of an interruption of the system voltage, 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 hast he 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
