Description
J. Schneider C-TEC 2440-4 P, Capacitor buffered Power Supply. The DC UPS of the C-TEC 2440 P series is equipped with integrated ultracapacitors for accumulating energy. During normal operation, this capacitor is charged by an internal charger which is supplied by an external, regulated DC power supply.
If the DC supply is interrupted, the energy of the ultracapacitors is released in an unregulated process (24,5 to 19 V DC). The load is supplied by the buffer module until the voltage is ≤ 19 V. The buffering time depends on the state of charge of the capacitor and discharging current. As a further function, the C-TEC 2440 P can provide more current for a certain time.
The DC-UPS shows the following features:
- Maintenance-free due to durable ultracapacitors
- reduces wiring time due to integrated energy storage
- 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
