    LEM LAS 100-TP LAS Series Current Transducer


    100A Rated Current x ±200A Measuring Range — Eta-Technology Sensor with Unipolar Supply for PCB Mounting

     

    LEM LAS 100-TP Product Overview

    The LAS 100-TP is a current transducer using Eta-technology from LEM's LAS 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 and a unipolar +5 V supply, combining the advantages of open-loop and closed-loop transducers . The device operates within a temperature range of -40°C to +85°C and offers a voltage output with fixed offset and gain .

    Rated for 100 A nominal with a ±200 A measuring range (extendable to ±300 A at frequencies >1 kHz), it outputs a ratiometric voltage of 2.5 V ± 0.625 V with 1% accuracy and <0.7% linearity . Reaction time is <200 ns and response time is <500 ns, with a bandwidth of DC to 100 kHz . Supply voltage is +5 V (±5%) with typical current consumption of 18 mA . Mass is 20 g and operating temperature is -40°C to +85°C . Insulation test voltage is 5 kV with creepage and clearance distances of 10.7 mm each, providing reinforced isolation up to 500 V according to EN 50178 and IEC 61010-1 standards .

    LEM LAS 100-TP Key Advantages

    The LAS 100-TP employs Eta-technology, delivering 1% accuracy and <0.7% linearity while combining the positive properties of open-loop and closed-loop current transducers . The ±200 A range provides ample headroom for measuring nominal currents up to 100 A with transient overcurrent capability (up to 3× IPN) , while the <500 ns response time and 100 kHz bandwidth capture fast-changing switching waveforms with high fidelity . The PCB-mount design with integrated primary conductor simplifies board-level integration, and the unipolar +5 V supply eliminates the need for dual supplies . The reference access pin provides flexible signal conditioning, and the 5 kV insulation with UL 94-V0 rated housing ensures robust safety isolation .

     

    LEM LAS 100-TP Typical Applications

    AC variable speed and servo motor drives
    Static converters for DC motor drives
    Battery supplied applications
    Uninterruptible Power Supplies (UPS)
    Renewable energy systems
    Combiner boxes and MPPT

     

    Why Choose the LEM LAS 100-TP?

    The LAS 100-TP combines a 100 A nominal rating with a ±200 A measuring range and 1% accuracy in a compact, PCB-mount package with unipolar +5 V supply . Manufactured by LEM, it delivers stable, accurate, and safe current measurement for industrial power conversion and motor control applications. The Eta-technology 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 device conforms to EN 50178 standards and is covered by LEM's 5-year guarantee, ensuring long-term reliability .
