AHR Series Split-Core Hall Effect Sensors
LEM compact and versatile split core transducers are for high AC and DC currents from 500 A to 2,000 A
LEM AHR series is designed for the electronic measurement of DC, AC, and pulse currents with galvanic separation and high insulation between the primary circuit and the secondary circuit. The ability to eliminate insertion losses and ease of installation are two of the main advantages of the AHR series.
