    LEM LT 1005-S/SP26 LT1005 Series Closed Loop Current Transducer

    LEM LT 1005-S/SP26 Product Overview

    The LT 1005-S/SP26 is a closed-loop Hall effect current transducer from LEM's LT1005 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 40.5 x 40.5 mm aperture for primary conductor crossing and is specifically designed for railway traction applications .

    Rated for 1000 A nominal with a measuring range of 2800 A, it outputs a secondary current of 250 mA at nominal with ±0.4% accuracy and ±0.1% linearity . Response time is 1 µs and frequency bandwidth is DC to 150 kHz . Supply voltage is ±24 V . Mass is 550 g and operating temperature ranges from -40°C to +85°C . The insulating plastic case is recognized according to UL 94-V0 .

    LEM LT 1005-S/SP26 Key Advantages

    The LT 1005-S/SP26 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 40.5 x 40.5 mm aperture enables non-intrusive installation of primary conductors without disconnecting existing cables. The 2800 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 wide -40°C to +85°C operating temperature range ensures reliable performance in harsh railway environments. The design offers excellent accuracy, very good linearity, low temperature drift, optimized response time, high immunity to external interference, and no insertion losses .

     

    LEM LT 1005-S/SP26 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
    Circuit breakers for railway infrastructure

     

    Why Choose the LEM LT 1005-S/SP26?

    The LT 1005-S/SP26 combines a 1000 A rated current and 2800 A measuring range with a 250 mA closed-loop current output in a robust panel-mount package with a 40.5 x 40.5 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 with low temperature drift, while the aperture and modular design simplify installation and system integration. The extended -40°C to +85°C operating temperature range ensures reliable operation in demanding rail environments, making it an ideal choice for propulsion, braking, and auxiliary converter systems.
