Product Specification
| Description | Current Sensors RoHS | Mfr. Part # | HAH1DR 900-S |
| Model Number | HAH1DR 900-S |
The LEM HAH1DR 900-S is an open-loop Hall effect current transducer designed for high-power automotive applications. It provides galvanic isolation between the primary and secondary circuits, enabling the electronic measurement of DC, AC, or pulsed currents. With a compact design and a choice of current measuring ranges up to 900 A, this transducer offers excellent accuracy, linearity, and low thermal drift. Its advantages include a wide frequency bandwidth and no insertion losses, making it ideal for battery monitoring, starter generators, inverters, and HEV/EV applications.
