Abstract: Some appliances, normally supplied by a mains supply, comprise an emergency supply by batteries able to take over from the mains supply. The batteries used by the emergency supply are generally protected by a fuse. These appliances may consume energy greater than what could be supplied by the batteries of the emergency supply. When there is a break in the mains electrical supply, it's preferable to limit the current consumed by the appliance to not damage the fuse protecting said batteries. However, the fuses are hardware modules having a reaction time of a few hundreds of milliseconds. If one does not want to damage the fuse, one could reduce the current consumption of the appliance within a time less than the reaction time of the fuse. A system and method herein instantaneously reduces the electrical consumption of an appliance in the event of a break in the mains supply.
