LF-1010-S 1000A 38mm 5000:1 Hall Effect Ratio Based Closed Loop Current Transformer by LEM

The LF 210-S, LF 510-S, LF 1010-S, and LF 2010-S Closed Loop ASIC based Hall effect current sensor measures DC, AC pulse currents' of 200, 500, 1000, 2000 ARMS (respectively)  nominal with galvanic isolation.

The LF 205-S/SP3 and LF 210-S/SP3  and Closed Loop ASIC based Hall effect current sensor measures DC, AC pulse currents' of 100 ARMS nominal with galvanic isolation.
