CKSR Board Mount Current Transducers

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