J. Schneider AC C-TEC 2420-8, Capacitor buffered Power Supply. The DC-UPS of the series AC CTEC includes ultra-capacitors as energy storage inside the housing. During normal operation the power supply supplies the connected loads and charges at the same time the capacitors. In case of an interruption of the mains supply, the energy of the ultra-capacitors is released regulated. The load is supplied by the back-up module until the ultra-capacitors are discharged. The back-up time depends on the state of charge of the capacitors and on the discharge current.

 

The DC-UPS has the following characteristics:

  • Maintenance-free because of long-life ultra-capacitors
  • Microcontroller based charging and discharging of the ultra-capacitors
  • Control of operation and status of charge with potential-free contacts and LED
  • Low wiring effort necessary because of the integration of mains adaptor and energy store compatible to TECControl shutdown-software
  • Communication with an IPC via USB or RS232 cable possible adjustable with USB interface
  • Capacity extension possible with external capacitor extension modules
  • Cyclic capacitor test during mains operation
  • Big temperature range -40 C up to 60 C
