電気メーター

Smart electricity meters give building managers insight into and control over energy use. Littelfuse makes the solid state relays, microcontrollers, and cartridge fuses that make these invaluable environmental and budgeting tools work. From magnetic sensors that control meter access to ESD protection devices that prevent shocks and shorts due to human–machine interactions, we deliver solutions.
