CAS Board Mount Current Transducers

LEM CAS Board Mount Current Transducers are designed for accurate electronic measurement of DC, AC, and pulsed currents, ranging from 1.5A RMS to 75A RMS, with galvanic isolation between the primary and secondary circuits. These Fluxgate-based transducers operate on a single +5V supply, ensuring low offset and gain drift. With a measuring range extending up to three times the nominal primary current (Ipn), the transducers offer high precision and reliability for various applications. Additionally, the LEM CAS sensors are designed for PCB mounting, making them easy to integrate into electronic systems.
