FSM500LFBH

The FSM500LFBH is a current sensor that applies the fluxgate principle to measure DC, AC, pulse and various irregular waveforms under galvanic isolation. The FSM500LFBH is characterized by high accuracy and linearity, high sensitivity and resolution, very low out-of-phase current and temperature drift. Widely used in instrumentation, medical equipment, metrology and calibration, laboratories, high-precision power supplies, new energy vehicles and so on.
