Hall Current Sensor 150A


3 in stock

Current sensor based on the Hall effect. Targeted at systems that do not have a built-in current sensor or system integrators who want to avoid voltage drop or excessive heat generation as with traditional resistor-based current sensors.


Current sensor that benefits from the Hall effect. Aimed mainly at systems that do not have a built in current sensor or for system integrators who dont want any voltage drops or heat build up like can occur with traditional resistor based measuring techniques.
