The HAH1BV and HAH1DR family is best suited for DC, AC or pulse current measurement in high power and low voltage automotive battery monitoring (BV) and Motor Drive (DR) applications. It contains a galvanic isolation between the primary circuit (high power) and the secondary circuit (electronic circuit).

The HAH1BV and HAH1DR family gives you the choice of having different peak currents (from+/- 200A up to +/- 900A) in the same housing.
