HO Family

The HO current transducer series, encompassing sensors from the HO-P, HO-S, HO-NP, HO-NSMPR, and HO-NPPR Series, is meticulously designed for the precise measurement of DC, AC, and pulse currents while ensuring galvanic isolation between the primary and secondary circuits. Key features of the HO series include:

• Wide Current Measurement Range: The HO sensors cover a current measurement range from 6 ARMS to 250 ARMS, catering to diverse current measurement needs.
• Variety in Mounting Options: While most of the HO series is designed for exclusive PCB mounting (through hole or surface mounting), the HO-S series is an exception, specifically designed for panel mounting via its 15x8 mm large aperture.
• Short Response Time and High Accuracy: The entire HO series offers short response times, low offset and gain drift, and high accuracy, ensuring reliable current measurements.
• Multirange Features: The HO-NP Series provides multirange capabilities, allowing for small current measurements from 10 to 150 A nominal, with a configuration of four primary pins for each model.
• Intelligent and Programmable Sensors: The HO-NSMPR and HO-NPPR series stand out as intelligent and interactive current transducers. Users can program these sensors, offering features such as programmable ranges (8 ARMS, 15 ARMS, 25 ARMS), overcurrent detection with programmable thresholds, programmable response time, and up to four programmable internal reference voltages.
• Open-Loop Hall Effect Technology: The HO sensors operate based on open-loop Hall effect sensor technology, ensuring accuracy and reliability in industrial applications where precise current measurements are crucial.

Overall, the diverse features and options within the HO series make it suitable for a wide range of industrial scenarios, meeting various current measurement requirements.
