eLansense™ directly replaces standard fuses with an efficient electronic high side switch.

eLansense™ improves safety by preventing fire and electrocution by eliminating the negative effects of temperature, such as localised heating and the risk of arcing, whilst integrating within existing infrastructure without alteration.

The intelligence of eLansense™ provides a distributed energy management and energy local area network by simply changing a fuse.

eLansense™ precisely controls and monitors the current passing through it with full diagnostics over wireless communications.

eLansense™ is fully self-contained and compatible with standard fuse holders with no consumable parts and is powered from the single positive power rail being protected.

eLansense™ 625 replaces standard fuses commonly found in domestic appliances and UK plugs, and eLansense™ 1038 replaces the MIDGET fuses commonly found in Industrial, medical and renewable energy applications.
