    LEM HAH1DRW 200-S Open-Loop Hall Effect Current Sensor

     

    LEM HAH1DRW 200-S Product Overview

    The HAH1DRW 200-S is a high-precision current sensor from LEM's HAH1DRW series, based on open-loop Hall effect technology. It is designed for electronic measurement of DC, AC, and pulsed currents, with galvanic isolation between the primary and secondary circuits.

    The key advantage of this model is its redundant/dual range design, featuring two independent output channels (high-range and low-range) to provide measurement redundancy for automotive safety-critical applications. The sensor has a rated current of 200A, a measuring range of ±200A, and outputs a ratiometric voltage signal (instantaneous 2.5V ± 2V) with a sensitivity of 10mV/A. Accuracy is 2.25%, linearity is ±1%, bandwidth is 40kHz, and response time is 6µs. It operates on a single +5V supply (4.75V ~ 5.25V) with a temperature range of -40°C to +125°C.

    The busbar mounting design makes it suitable for automotive Battery Management Systems (BMS) and high-power motor control applications. The HAH1DRW series offers measurement ranges from ±120A to ±1200A in the same package, enabling flexible platform-based selection.
