LEM’s series of dual-range, automotive-qualified sensors are designed for accurate, wide-range current measurements in vehicle battery monitoring applications. The 25 models in the DHAB family offer non-intrusive, galvanically-isolated solutions in this arena.
A DHAB Hall-effect sensor is fixed onto the battery cable of a car. Its two cores allow it to be used for two separate current ranges – one between ±20 A and ±80 A and the other between ±50 A and ±600 A.
The sealed housing of the DHAB sensors means that no potting is required. Panel and cable-mount versions are available to offer maximum mounting versatility. The sensors meet all relevant standards, including ISO-TS and RoHS.
The DHAB sensors are covered by a five-year guarantee. Principal applications are expected to be in the measurement of battery-pack current in electric and hybrid vehicles.
