<p>The invention concerns a system supplying uninterruptedly sensitive equipment having a supply interface of 230V/50 Hz, characterised in that it comprises, downstream of a high voltage/low voltage transformation station, a direct connection towards at least one Uninterrupted Power Supply (UPS), enabling to eliminate the Normal/Standby switch between the local electric network and the replacement source. The UPS, which comprises batteries in parallel and a quick switching device (t < 20 ms), automatically ensures the launching (or triggering) of the standby source in case of breakdown of the local electric power supply network. Reciprocally the standby source, which is directly coupled with the UPS batteries, delivers the direct current required for maintaining the charge of said batteries.</p> |
