AC C-TEC 2403-1-400

Capacitor buffered Power Supply

Type       :   AC-C-TEC 2403-1 (400 V)
Art.-No.  :   NCPA0724G01020

 

 

Short description

The DC-UPS of the AC C-TEC 2403 series is equipped with a integrated power supply and ultracapacitors for accumulating energy. During normal operation this capacitor is charged by an internal charger which is supplied by the internal, regulated DC power supply. If the AC supply is interrupted, energy of the ultracapacitors is released in a regulated process (24 V DC ±2%). The load is supplied by the buffermodul until the capacitors are discharged. The buffering time depends on the state of charge of the capacitor and discharging current. 

 

The DC-UPS shows the following features:

  • Maintenance-free due to durable ultra capacitors
  • reduces wiring time due to intergrated energy storage and power supply
  • Microcontroller based charging and discharging of the ultracapacitors
  • Input voltage-signal via potential-free contact and LED
  • Short overload possible
  • Vibration secured wiring via spring loaded plugs
  • Wide working temperature range -40°C till 60°C
