    Product Detail: LEM LA25-NP/SP9 – High-Precision Closed-Loop Hall Effect Current Transducer for Small Currents

    In modern electronic measurement and industrial control, accurate monitoring of small currents is often the key to system performance and safety. As a global leader in electrical transducers, LEM (Switzerland) has long specialized in current and voltage sensing. Its LA25-NP/SP9 closed-loop Hall effect current transducer is specifically designed to measure a rated current of 1.5 A with outstanding accuracy, fast response, and high immunity to interference – making it the perfect choice for your precision control system.

     

    Key Highlights – Why Choose the LEM LA25-NP/SP9?

    Closed-loop Hall technology for high accuracy
    Based on the closed-loop (compensated) Hall effect principle, the transducer offers a rated current of 1.5 A and a measuring range of 0 to ±2.2 A. With an accuracy of ±0.5%, linearity error <0.2%, and total error <0.2%, every data acquisition is reliable.

    Extremely fast response to capture transient changes
    Response time <1 µs and bandwidth DC to 150 kHz enable accurate measurement of DC, AC, pulsed, and mixed currents – delivering real-time feedback for high-speed dynamic control.

    High isolation for safety
    Galvanic isolation between primary (power) and secondary (measurement) circuits provides 2.5 kVrms isolation voltage and an insulation resistance >1500 MΩ, ensuring operator and equipment safety.

    Excellent anti-interference and low drift for harsh environments
    High immunity to external interference and very low temperature drift. Operating temperature range 0 °C to +70 °C; storage temperature from -25 °C to +85 °C – suitable for demanding industrial conditions.

    Fully insulated, PCB-mount package
    Plastic case certified UL 94-V0. Compact PCB-mount design for easy integration.
