    LEM LTC 600-S/SP15 LTC Series Closed Loop Current Transducer

    LEM LTC 600-S/SP15 Product Overview

    The LTC 600-S/SP15 is a closed-loop Hall effect current transducer from LEM's LTC 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 a 42 mm diameter aperture for primary conductor installation and is specifically designed for railway traction applications .

    Rated for 600 A nominal with a measuring range of 0 to ±1500 A, it outputs a secondary current of 200 mA at nominal with ±0.7% accuracy and <0.1% linearity . Turns ratio is 1:3000 . Response time is <1 µs for a di/dt of 100 A/µs, and frequency bandwidth is DC to 100 kHz . Supply voltage range is ±15 V to ±24 V DC . Mass is 635 g and operating temperature ranges from -40°C to +85°C . Insulation test voltage is 13.4 kV RMS at 50 Hz for 1 minute between primary and secondary, with 64.2 mm creepage and 45.9 mm clearance . The device meets EN 50155 railway standards .

    LEM LTC 600-S/SP15 Key Advantages

    The LTC 600-S/SP15 employs closed-loop Hall effect technology, delivering ±0.7% accuracy and <0.1% linearity while providing galvanic isolation between primary and secondary circuits . The 42 mm aperture enables non-intrusive installation of primary busbars without disconnecting existing conductors . The ±1500 A measuring range accommodates high overload conditions, while the <1 µs response time and 100 kHz bandwidth capture dynamic current signals in traction applications . The wide -40°C to +85°C operating temperature range and 635 g lightweight design ensure reliable performance in harsh railway environments . The 13.4 kV RMS insulation and UL94-V0 recognized insulating plastic case ensure safe operation and protection for downstream equipment . Secondary connections are provided on a WAGO 722-234/031-000 connector for simplified wiring .

     

    LEM LTC 600-S/SP15 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
    Battery chargers for railway rolling stock
    Railway fixed installations and trackside equipment
    Overcurrent protection and fault detection in traction systems
    Variable speed drives for railway applications

     

    Why Choose the LEM LTC 600-S/SP15?

    The LTC 600-S/SP15 combines a 600 A rated current and ±1500 A measuring range with a 200 mA closed-loop current output in a robust panel-mount package with a 42 mm aperture . 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, while the through-hole aperture allows easy installation without system interruption . The 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 .
