The momentary stopping of equipments (industrial machines, computer equipment,...) because of power cuts in the electrical energy distribution can have serious technical or financial consequences. That is why it is often vital, in the worlds of industry and building, to secure the supplying of the installations.

The system CS4000 of Macq électronique is the solution to carry out automatically the commutation between 2 independent sources of energy in case of failure of one of them. Any damaging, stopping of equipments or disruption for their users is so eliminated.
The CS4000 functions according to the principle of a source commutation through static commutation thanks to the use of standard industrial static relays with instantaneous functioning.
The commutation is carried out in some milliseconds in a total openness for the users. The admissible power extends from 20 to 150 kVA with a single or three-phase current.
