    LEM LT 1005-T/SP3 LT Traction Series Closed Loop Current Transducer

    LEM LT 1005-T/SP3 Product Overview

    The LT 1005-T/SP3 is a closed-loop Hall effect current transducer from LEM's LT Traction Series, designed for the electronic measurement of DC, AC, and pulsed currents with galvanic isolation between the primary circuit and the secondary circuit . This panel-mount transducer features an integrated busbar and is specifically designed for railway traction applications .

    Rated for 1000 A nominal with a measuring range of ±1800 A, it outputs a secondary current of 333 mA at nominal with 0.4% accuracy and <0.1% linearity . The turns ratio is 1:3000 . Response time is <1 µs and frequency bandwidth is DC to 150 kHz . Supply voltage range is ±15 V . Mass is 1.2 kg and operating temperature ranges from -25°C to +70°C . The device meets EN 50155 railway standards .

    LEM LT 1005-T/SP3 Key Advantages

    The LT 1005-T/SP3 employs closed-loop Hall effect technology with an insulating plastic case recognized according to UL 94-V0, delivering 0.4% accuracy and <0.1% linearity while providing galvanic isolation between primary and secondary circuits . The integrated busbar simplifies installation and ensures reliable primary connections. The ±1800 A measuring range accommodates significant overload conditions, while the <1 µs response time and 150 kHz bandwidth capture dynamic current signals in traction applications . The design offers excellent accuracy, very good linearity, low temperature drift, optimized response time, high immunity to external interference, and no insertion losses . Secondary connections are made via M4 threaded studs for secure and reliable wiring, and the device is potted for enhanced environmental protection .

     

    LEM LT 1005-T/SP3 Typical Applications

    Single or three phase inverters for railway traction
    Propulsion and braking choppers
    Propulsion converters for trains and locomotives
    Auxiliary converters for onboard power supply
    Railway fixed installations and trackside equipment
    Overcurrent protection and fault detection in traction systems
    Battery chargers for railway rolling stock
    Circuit breakers for railway infrastructure

     

    Why Choose the LEM LT 1005-T/SP3?

    The LT 1005-T/SP3 combines a 1000 A rated current and ±1800 A measuring range with a 333 mA closed-loop current output in a robust panel-mount package with an integrated busbar. Manufactured by LEM, it delivers stable, accurate, and safe current measurement specifically for railway traction applications. The closed-loop Hall effect design provides exceptional accuracy and linearity with low temperature drift, while the integrated busbar simplifies installation and system integration. Compliance with EN 50155 railway standards ensures reliable operation in demanding rail environments, making it an ideal choice for propulsion, braking, and auxiliary converter systems.
