    LEM LT 2005-S/SP15 Closed-Loop Hall Effect Current Transducer

     

    LEM LT 2005-S/SP15 Product Overview

    The LT 2005-S/SP15 is a closed-loop Hall effect current transducer from LEM's LT2005 series, designed for electronic measurement of DC, AC, and pulsed currents with galvanic isolation between the primary and secondary circuits . It is specifically optimized for traction applications including railway propulsion and braking choppers, traction converters, and auxiliary converters .

    This SP15 variant features a ±24V fixed supply, 2000A nominal rating, and AMP CPC connector for secondary output . The sensor has a 60.5 × 20.5 mm aperture (or 56mm diameter) for the primary conductor crossing . It includes a shield as standard and a Hall cell at 90° configuration for traction applications . The turns ratio is 1:5000 .

    This model is rated for 2000A nominal current with a measuring range of ±3500A (1.75× overload capability), outputting a 400mA instantaneous current signal with 0.3% accuracy . It operates on a ±24V fixed bipolar supply, with a DC~100kHz bandwidth and a <1µs response time . The sensor operates over a temperature range of -25°C to +70°C .

    LEM LT 2005-S/SP15 Core Advantages

    Closed-Loop Hall Technology with Active Compensation: Delivers 0.3% accuracy and <0.1% linearity across the full measuring range, eliminating core saturation errors found in open-loop sensors .

    ±3500A Wide Measuring Range with 1.75× Overload Capability: The 2000A nominal sensor can measure up to ±3500A peak, providing ample safety margin for traction system transients and fault conditions .

    12kV High-Insulation Withstand Voltage: Provides 12kV RMS insulation test voltage between primary and secondary + shield, ensuring safety in demanding railway traction environments .

    <1µs Fast Response + 100kHz Bandwidth: Captures fast IGBT switching transients and high-frequency current components with >50A/µs di/dt following capability .

    AMP CPC Connector for Secondary Output: SP15 variant features AMP CPC connector for secure and reliable secondary connections, suitable for traction applications .

    Traction-Grade Design: Specifically designed for railway propulsion converters, braking choppers, and auxiliary converters, with shield and Hall cell at 90° configuration .

    Low Temperature Drift: Excellent offset and gain stability over the -25°C to +70°C operating range, with thermal drift of ±0.2 to ±0.3mA .

    UL 94-V0 Flame Retardant Case: Certified safety housing for demanding industrial and railway environments .

    No Insertion Losses: Non-contact Hall measurement adds no energy loss to the primary circuit .

    High Immunity to External Interference: Built-in shield and closed-loop compensation design provide excellent rejection of external magnetic fields .

     

    LEM LT 2005-S/SP15 Target Applications

    The LT series is specifically designed for traction applications :

    Railway Traction Systems: Traction converters, auxiliary converters

    Propulsion and Braking Choppers

    Single-phase or three-phase inverters

    Battery chargers

    AC Variable Speed Drives and Servo Motor Drives
