HO Multi-Range Current Transducers

LEM HO Multi-Range Current Transducers comprise the HO-NP, HO-NSM, HO-P, and HO-S Series. The LEM HO transducers are designed for precise DC, AC, and pulse current measurement while maintaining galvanic isolation between the primary and secondary circuits. With a wide current measurement range from 6ARMS to 250ARMS, these sensors cater to diverse applications. Most HO sensors are designed for PCB mounting, either through-hole or surface mount, except for the HO-S series. The HO-S features a 15x8mm aperture for panel mounting. Key performance benefits include short response times, low offset and gain drift, and high accuracy, ensuring dependable current measurements across various environments.
