CDS products avoid breaking of the central circuit-breaker when power consumption exceeds the power subscribed by the consumer. To this end, they temporarily break supply to circuits considered to be non-priority circuits as soon as the total current drawn exceeds a pre-set threshold. They also enable reduction of the electricity bill by authorising reduction of subscribed demand. These products, installed in the electrical switchboard, are designed to be implemented by an electrical contractor.
The Acti 9 CDS range consists of:
Acti 9 CDS: single-phase load shedding of 2 circuits in cascade mode
Acti 9 CDS: 3-phases load shedding (one circuit on each of the 3 phases)
Acti 9 CDSc: single-phase load shedding of 4 circuits in cascade-cyclic mode.
Ratings: priority channel adjustable from 5 to 90 A, non priority channels 15 A
Voltage rating: - single phase: 240 V A + 5 % - 10 %, - 3-phase: 415 V AC + 5 % - 10 %
Frequency: 50 /60 Hz
Indication of load shedding by LED
Restoration period: 5 to 10 min.
Load shedding override input
1A rating NO contact allowing remote indication of load shedding or direct load shedding via a NC contactor.
To prevent over-consumption
Reduce the electricity bill: load shedding reduces the power subscribed when the subscription was removed
Increase the number of loads that can be managed, without increasing subscribed demand
Enhance continuity of supply: as soon as the power consumed by the installation approaches the power set on the product, Acti 9 CDSs shed non-priority loads in cascade.
Acti 9 CDS s are especially designed to manage load shedding of electrical loads in residential and tertiary installations up to 36 kVA
