LEM HX 10-NP Current Transducer
HX 10-NP Current Transducer Overview
The HX 10-NP by LEM is a current transducer designed for precise measurement of AC, DC, and pulsed currents in power electronics applications. Using open-loop Hall effect technology, it provides galvanic isolation between primary and secondary circuits, ensuring safe and reliable operation in high-voltage systems. It is suitable for motor drives, uninterruptible power supplies (UPS), and renewable energy systems, where accurate current measurement is required.
The HX 10-NP operates within a supply voltage range of ±12V to ±15V and provides a voltage output of 4V nominal. Its compact design, requiring only 2.93 cm² of PCB mounting area, fits well in space-constrained industrial and commercial applications. The transducer offers an accuracy of ±1% and a temperature range of -25°C to +85°C, maintaining consistent performance under different environmental conditions.
The dual primary conductor design allows flexible current measurement configurations, supporting 10 ARMS and 20 ARMS nominal measurements. Its construction provides high immunity to external interference, making it suitable for demanding applications in power electronics.
