Eta based current sensor
The LAS product series is tailored for measuring DC, AC, and pulse currents with nominal values ranging from 50 to 100 ARMS, while providing galvanic isolation.
Featuring a compact design, LAS current sensors are intended for PCB mounting and offer a measuring range up to 3 x Ipn.
These sensors incorporate an integrated primary conductor and operate within a temperature range of -40 to +85°C. Equipped with a single +5 V supply, LAS sensors offer reference access and provide voltage output, fixed offset, and gain.
They utilize Eta technology, which combines the positive properties of both open loop and closed loop current sensors to ensure reliable and accurate current measurements in industrial applications.
