    LEM HY 50-P HY Series Open-Loop Hall Effect Current Transducer

    LEM HY 50-P Product Overview

    The HY 50-P is an open-loop Hall effect current transducer from LEM's HY series, designed for the electronic measurement of DC, AC, and pulsed currents with galvanic isolation between the primary and secondary circuits . The HY series features a compact design for PCB mounting and offers a ratiometric voltage output .

    Rated for 50 A nominal with a ±150 A measuring range (3 x IPN), it outputs a ratiometric voltage signal with ±1% accuracy and ±1% linearity . Response time is 3 µs and bandwidth is DC to 50 kHz . Supply voltage is ±15 V . Maximum supply current is 10 mA . Mass is <14 g and operating temperature is -10°C to +80°C . Insulation test voltage is 2.5 kV with an insulated plastic case recognized according to UL 94-V0 .

    LEM HY 50-P Key Advantages

    The HY 50-P employs open-loop Hall effect technology, delivering ±1% accuracy and ±1% linearity while providing galvanic isolation between primary and secondary circuits . The ±150 A measuring range provides 3x overload capability, while the 3 µs response time and 50 kHz bandwidth capture moderate-speed transients . The PCB mount design enables direct board-level integration, and the low current consumption (10 mA) minimizes power demands . The ratiometric voltage output simplifies interfacing with standard measurement systems. The UL 94-V0 insulated case ensures flame-retardant protection in industrial environments .

     

    LEM HY 50-P Typical Applications

    General purpose inverters
    AC variable speed 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 HY 50-P?

    The HY 50-P combines 50 A rating, ±150 A measuring range, ±1% accuracy, 3 µs response time, and 2.5 kV insulation in a compact PCB-mount package weighing just 14 g. Manufactured by LEM, it delivers stable, accurate, and safe current measurement for industrial applications . The HY series offers open-loop Hall effect sensing with ratiometric voltage output, ensuring reliable performance in general purpose inverter, drive, and power supply applications .
