    LEM LTC 1000-S Closed-Loop Hall Effect Current Transducer

     

    LEM LTC 1000-S Product Overview

    The LTC 1000-S is a closed-loop Hall effect current transducer from LEM's LTC 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.

    The sensor features a compact modular design with a 27.5mm aperture for the primary conductor crossing. Secondary connections support dual fastening modes: either 4×M5 threaded studs or 4×Faston (6.3×0.8mm) tabs. Panel mounting is achieved via 4 slots (Ø5.5mm) with M5 screws.

    This model is rated for 1000A nominal current with a measuring range of ±2100A (2.1× overload capability), outputting a 250mA instantaneous current signal with 0.6% accuracy and ±0.1% linearity. It operates on a ±15V to ±24V bipolar supply, with a DC~100kHz bandwidth and a <1µs response time.

    The sensor features a 12kV RMS insulation test voltage (between primary and secondary), ensuring high-voltage safety in demanding traction environments. It operates over a temperature range of -40°C to +85°C and is compliant with EN 50155 railway standards.

    LEM LTC 1000-S Core Advantages

    Closed-Loop Hall Technology with Active Compensation: Delivers 0.6% accuracy and ±0.1% linearity across the full measuring range, eliminating core saturation errors found in open-loop sensors.

    ±2100A Wide Measuring Range with 2.1× Overload Capability: The 1000A nominal sensor can measure up to ±2100A peak, providing ample safety margin for traction system transients and fault conditions.

    12kV Ultra-High Insulation Withstand Voltage: Provides 12kV RMS insulation test voltage, ensuring superior safety in demanding railway traction environments.

    <1µs Fast Response + 100kHz Bandwidth: Captures fast IGBT switching transients and high-frequency current components for protection and control applications.

    Traction-Grade Design with EN 50155 Compliance: Designed for railway propulsion converters, braking choppers, and auxiliary converters with -40°C to +85°C operating range.

    Dual Secondary Connection Modes: Supports both M5 threaded studs (recommended torque 2.2Nm) and Faston 6.3×0.8mm tabs for flexible installation options.

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

    Low Temperature Drift: Excellent offset and gain stability over the wide -40°C to +85°C operating range.

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

    Active Part Status with Full Manufacturer Support: Currently in production with full LEM support.
