FSM300LDGH

Name: FSM300LDGH
Brand: KELI
SKU: 256082411

Current sensors applying the fluxgate principle can measure DC, AC, pulse and various irregular waveforms under galvanic isolation conditions.They have high accuracy and linearity, high sensitivity and resolution, very low out-of-phase current and temperature drift. Widely used in instrumentationmeters, medical equipment, metrology and calibration, laboratories, high-precision power supplies, new energy vehicles and so on.
