    LEM HAIS 150-TP HAIS Series Open-Loop Current Transducer


    150A Rated Current x ±450A Measuring Range — Voltage Output Sensor with Integrated Primary Busbar for Industrial Applications

     

    LEM HAIS 150-TP Product Overview

    The HAIS 150-TP is an open-loop Hall effect current transducer from LEM's HAIS 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 is equipped with an integrated primary busbar, simplifying installation and ensuring reliable connections for high-current measurement . The device operates from a single +5 V power supply and provides a voltage output with fixed offset and sensitivity.

    Rated for 150 A nominal with a ±450 A measuring range, it outputs an analog voltage of 2.5 V ± 0.625 V with 1% accuracy and ±0.5% linearity . Response time is 5 µs and bandwidth is DC to 50 kHz . Supply voltage is +5 V (±5%) with a maximum current consumption of 19 mA . Mass is 30 g and operating temperature is -40°C to +85°C . Insulation test voltage is 2.5 kV with creepage and clearance distances exceeding 8 mm and a CTI > 600 .

    LEM HAIS 150-TP Key Advantages

    The HAIS 150-TP employs open-loop Hall effect technology, delivering 1% accuracy and ±0.5% linearity while maintaining a compact footprint and low power consumption . The ±450 A range provides generous headroom for measuring nominal currents up to 150 A with transient overcurrent capability, while the 5 µs response time and 50 kHz bandwidth capture fast-changing switching and pulse waveforms with high fidelity. The PCB-mount design with integrated primary busbar simplifies board-level integration and saves space, and the unipolar +5 V supply simplifies power design. The reference access pin offers flexible signal conditioning, and the 2.5 kV insulation with UL 94-V0 recognized housing ensures robust safety isolation for industrial applications .

     

    LEM HAIS 150-TP 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
    Renewable energy systems

     

    Why Choose the LEM HAIS 150-TP?

    The HAIS 150-TP combines a 150 A nominal rating with a ±450 A measuring range and 1% accuracy in a compact, PCB-mount package with an integrated primary busbar and +5 V supply . Manufactured by LEM, it delivers stable, accurate, and safe current measurement for demanding industrial power conversion and motor control applications. The open-loop Hall effect design offers excellent linearity, low thermal drift, and high immunity to external interference, making it a reliable and cost-effective choice for critical systems where measurement integrity is paramount. The TP variant's integrated busbar simplifies installation and reduces component count, ideal for applications where space is at a premium .
