    LEM LTC 1000-T LTC Series Closed Loop Current Transducer

    LEM LTC 1000-T Product Overview

    The LTC 1000-T 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 separation 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 0 to ±2400 A, it outputs a secondary current of 200 mA at nominal with ±0.4% overall accuracy (at 25°C) and <0.1% linearity . Response time is <1 µs and frequency bandwidth is DC to 100 kHz . Supply voltage range is ±15 to ±24 V DC. Mass is 1270 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, with 83.2 mm creepage and 54.4 mm clearance . The device meets EN 50155:2017 railway standards .

    LEM LTC 1000-T Key Advantages

    The LTC 1000-T employs closed-loop Hall effect technology, delivering exceptional accuracy and very good linearity while providing galvanic isolation between primary and secondary circuits . The integrated busbar simplifies installation in railway systems, and the modular design enables flexible horizontal or vertical mounting . The ±2400 A measuring range accommodates significant 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 13.4 kV RMS insulation ensure reliable performance and safe operation in harsh railway environments . The insulating plastic case is recognized according to UL 94-V0, and a standard shield provides immunity to external interference . Secondary connections are available via 4xM5 threaded studs or 4xFaston (6.3 x 0.8 mm) .

     

    LEM LTC 1000-T 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 substations
    Overcurrent protection and fault detection in traction systems
    Circuit breakers for railway infrastructure

     

    Why Choose the LEM LTC 1000-T?

    The LTC 1000-T combines a 1000 A rated current and ±2400 A measuring range with a 200 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, while the integrated busbar simplifies installation . The compliance with EN 50155:2017 railway standards ensures reliable operation in demanding rail environments, making it an ideal choice for propulsion, braking, and auxiliary converter systems .
