    LV 100/SP41 Voltage Transducer

     

    LV 100/SP41 High-Precision Closed-Loop Hall Effect Voltage Measurement Solution

    The LV 100/SP41 is a standout model in LEM’s LV100 series of voltage transducers, designed for industrial measurement of DC, AC, and pulsed voltages. As a world leader in electrical measurement, LEM has accumulated decades of experience and core expertise in voltage sensing technology – and the LV100 series is a flagship representative of that innovation.

    The transducer uses closed-loop Hall effect technology. For voltage measurement, an external resistor R1 is required to create a current proportional to the voltage to be measured, which flows into the primary circuit. This solution is suitable for nominal voltage measurements from 100V to 2500V, and is ideal for applications such as AC variable speed drives, servo motor drives, static converters, DC motor drives, uninterruptible power supplies (UPS), and railway traction equipment.

     

    LV 100/SP41 Key Features

    Closed-Loop Hall Effect Technology – Delivers superior accuracy, faster response time, and a wider frequency range compared to open-loop sensors, ensuring more reliable and stable measurements.

    ±0.7% High Accuracy – Maintains 0.7% measurement accuracy across the full operating temperature range, meeting demanding industrial requirements.

    Wide Temperature Range – Operates from -25°C to +70°C, ready for diverse environmental challenges.

    Flexible Power Supply – Supports external bidirectional DC supplies from 15V to 24V, compatible with a variety of system power configurations.

    Panel Mounting – Standard panel mount design for easy integration and maintenance.

    UL 94-V0 Insulated Case – Galvanic isolation between primary and secondary circuits ensures equipment and operator safety.

     

    LV 100/SP41 Applications

    Variable Frequency Drives & Servo Motor Drives – Accurately measure motor drive voltage to improve stability and energy efficiency in industrial automation.

    Static Converters for DC Motor Drives – Suitable for electric vehicles, industrial machinery, and other DC drive systems.

    UPS & Inverter Power Supplies – Ensure precise voltage monitoring for critical power equipment.

    Renewable Energy & New Energy Systems – Widely used in wind power converters, centralized solar inverters, and other new energy conversion systems.

    Railway Traction Systems – High-voltage measurement for fixed installations and locomotive traction equipment, meeting the stringent demands of rail applications.

    Battery-Powered Systems & Energy Management – Provide reliable voltage monitoring in energy storage systems and battery charge/discharge management.
