J. Schneider AC C-TEC 2403-05, 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 released 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 of the ultra-capacitors
- Control of operation and status of charge with potential-free contacts and LED
- Capacity extension is possible with external capacitor extension modules
