    LEM LA 150-TP/SP1 LA130/150 Series Closed-Loop Current Transducer


    150A Rated Current x ±212A Measuring Range — High-Accuracy PCB-Mount Sensor with Integrated Busbar for Industrial Power Conversion

     

    LEM LA 150-TP/SP1 Product Overview

    The LA 150-TP/SP1 is a closed-loop Hall effect current transducer from LEM's LA130/150 series, designed for the electronic measurement of DC, AC, and pulsed currents with galvanic isolation between the primary and secondary circuits . This PCB-mount sensor features an integrated primary conductor and a 13.5 x 10 mm aperture for primary conductor crossing . The SP1 variant offers a special busbar and basic insulation rated to 1500 V .

    Rated for 150 A nominal with a ±212 A measuring range, it outputs a secondary current of 75 mA (instantaneous) with 0.5% accuracy and ±0.1% linearity . Response time is 500 ns and bandwidth is DC to 150 kHz . Supply voltage range is ±12 V to ±15 V . Supply current is 10 mA maximum . Operating temperature is -40°C to +85°C . Mounting is PCB through-hole .

    LEM LA 150-TP/SP1 Key Advantages

    The LA 150-TP/SP1 employs closed-loop Hall effect technology, delivering 0.5% accuracy and ±0.1% linearity while maintaining excellent performance with low temperature drift, optimized response time, wide frequency bandwidth, and high immunity to external interference . The ±212 A range provides ample headroom for measuring nominal currents up to 150 A with transient overcurrent capability, while the 500 ns response time and 150 kHz bandwidth capture fast-changing switching waveforms with high fidelity . The PCB-mount design with integrated primary conductor simplifies board-level integration and saves valuable board space . The special busbar and 1500 V basic insulation of the SP1 variant ensure robust safety isolation for demanding applications .

     

    LEM LA 150-TP/SP1 Typical Applications

    Drives
    Power Supplies
    Renewable Energies
    Welding
    AC variable speed drives and servo motor drives
    Static converters for DC motor drives
    Uninterruptible Power Supplies (UPS)
    Switched Mode Power Supplies (SMPS)

     

    Why Choose the LEM LA 150-TP/SP1?

    The LA 150-TP/SP1 combines a 150 A nominal rating with a ±212 A measuring range and 0.5% accuracy in a compact, PCB-mount package with integrated primary conductor and special busbar . Manufactured by LEM, it delivers stable, accurate, and safe current measurement for demanding industrial power conversion and motor control applications. The closed-loop Hall effect design offers excellent accuracy, very good linearity, low thermal drift, and high immunity to external interference, making it a reliable choice for critical systems where measurement integrity is paramount. The SP1 variant's special busbar and 1500 V basic insulation provide a robust solution for industrial installations requiring enhanced isolation .
