| Short descriptionThe 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:
