LEM HAX Board Mount Current Sensors

LEM HAX Board Mount Current Sensors enable electronic measurements of DC, AC, or pulsed currents while ensuring galvanic isolation between the primary and secondary circuits. These LEM sensors provide an instantaneous voltage output ranging from ±4V, operate using a bipolar power supply of ±15V, and offer a DC bandwidth of 25KHz. Based on Hall effect open-loop technology, the HAX-S current sensors are specifically tailored for use in industrial applications.
