    LEM LA 25-NP/SP14 LA 25-NP Series Closed-Loop Current Transducer


    0.25A Rated Current x ±0.36A Measuring Range — High-Accuracy PCB-Mount Sensor for Low Current Measurement

     

    LEM LA 25-NP/SP14 Product Overview

    The LA 25-NP/SP14 is a closed-loop Hall effect current transducer from LEM's LA 25-NP series, designed for the electronic measurement of DC, AC, and pulsed currents with galvanic isolation between the primary and secondary circuits . This compact PCB-mount sensor features an integrated primary conductor with a 100:1000 turns ratio, providing high accuracy for low-current measurement applications .

    Rated for 0.25 A nominal with a ±0.36 A measuring range, it outputs a secondary current of 25 mA (instantaneous) with 0.5% accuracy and <0.2% linearity . Response time is <1 µs and bandwidth is DC to 150 kHz . Supply voltage is ±15 V (±5%) . Mass is 22 g and operating temperature is -10°C to +70°C . Insulation test voltage is 2.5 kV with basic isolation rated to 1700 V and safe separation to 600 V according to EN 50178 .

    LEM LA 25-NP/SP14 Key Advantages

    The LA 25-NP/SP14 employs closed-loop Hall effect technology, delivering 0.5% accuracy and <0.2% linearity while maintaining excellent performance with low temperature drift, optimized response time, wide frequency bandwidth, no insertion losses, and high immunity to external interference . The ±0.36 A range provides ample headroom for measuring nominal currents up to 0.25 A with transient overcurrent capability, while the <1 µs response time and 150 kHz bandwidth capture fast-changing pulse and AC waveforms with high fidelity. The PCB-mount design with integrated primary conductor simplifies board-level integration, and the UL 94-V0 recognized insulated plastic case ensures safety compliance . The 2.5 kV insulation and EN 50178 compliance guarantee robust safety isolation for industrial applications .

     

    LEM LA 25-NP/SP14 Typical Applications

    AC variable speed drives and servo motor drives
    Static converters for DC motor drives
    Battery supplied applications
    Uninterruptible Power Supplies (UPS)
    Switched Mode Power Supplies (SMPS)
    Power supplies for welding applications

     

    Why Choose the LEM LA 25-NP/SP14?

    The LA 25-NP/SP14 combines a 0.25 A nominal rating with a ±0.36 A measuring range and 0.5% accuracy in a compact, PCB-mount package designed for industrial low-current measurement applications . Manufactured by LEM, it delivers stable, accurate, and safe current measurement for power conversion and motor control systems. 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 SP14 variant provides the specific 100:1000 turns ratio configuration and operating temperature range of -10°C to +70°C, optimized for industrial environments .
