EM Series

Name: EM
Brand: ADISENS

Precision open-loop Hall-effect current sensing for compact power electronics.

The EM Series uses a high-sensitivity programmable Hall IC with factory digital calibration and compensation. It measures DC, AC and pulsed current with galvanic isolation, a 2.5 V centred analog output and support for 1, 2 or 3 primary turns.
