AC-C-TEC 2403-1

Capacitor buffered Power Supply

Type      :   AC-C-TEC 2403
Art.-No. :   NCPA0724G01017

 

 

Short description

 

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
