LEM DHAB S/133 Current Transducer, Open Loop Hall Effect, -75A to 75A/-750A to 750A, 3.3%, Ratiometric O/P, 5.25VDC

DHAB S/133 is an automotive current open loop transducer using the hall effect technology. It is best suited for DC, AC, or pulsed currents measurement in high power and low voltage automotive applications. It features galvanic separation between the primary circuit (high power) and the secondary circuit (electronic circuit). Automotive applications includes battery pack monitoring, hybrid vehicles, EV and utility vehicles.
