APR Series Split-Core Sensors
LEM split-core current sensors provide flexible and precise AC current measurement across a wide adjustable range
LEM APR series split-core current sensors provide flexible and precise AC current measurement across a wide adjustable range from 10 A to 400 A, making them well suited for dynamic installation environments. Available in true RMS versions, they offer selectable output formats—including 4 mA to 20 mA, 0 V to 5 V, and 0 V to 10 V—to match diverse monitoring and control system requirements, all supported by a broad 30 Hz to 6,000 Hz bandwidth and an 18 mm aperture. The series also includes two electronic variants: the B10, designed for voltage output configurations, and the B420L, tailored for current output applications. Built on LEM PRiME (Planar Rogowski I Measurement) air core technology, APR sensors deliver reliable, accurate performance for energy and automation applications where dependable current measurement is critical.
