CASR Board Mount Current Transducers

LEM CASR Board Mount Current Transducers are specifically designed for accurate electronic measurement of DC, AC, and pulsed currents, covering a range from 1.5A to 75A RMS. These sensors provide galvanic isolation between the primary and secondary circuits, ensuring enhanced safety and performance. Built with compact Fluxgate-based technology, the LEM CASR current sensors operate with a single +5V supply and exhibit minimal offset and gain drift. The CASR sensors also offer an extended measuring range up to three times the nominal primary current (Ipn), making them highly versatile. Additionally, these transducers are designed for direct PCB mounting, featuring three primary pins for efficient handling of small current measurements from 2A to 50A RMS.
