The DC-UPS of the AC C-TEC 2403 series is equipped with an 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, the energy of the ultracapacitors is released in a regulated process (24 V DC ±2%). The load is supplied by the buffer module 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:
The DC-buffer module C–TEC works with Ultra-capacitors as energy storage inside the housing. In case of an interruption of the DC supply, the energy of the Ultracapacitors is released. The load is energized from the buffer module, til it is discharged. The backup time depends on the state of charge of the capacitors and on the discharge current.
- Maintenance-free due to durable ultracapacitors
- reduces wiring time due to integrated 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
