    ‌LT1005-S Closed-Loop Hall Effect Current Sensor — The Ultimate Choice for Industrial High-Precision Current Monitoring‌

     

    ‌LT1005-S ‌Product Overview‌

    The LT1005-S is a closed-loop Hall effect current sensor engineered by ‌LEM (Lem)‌ for demanding industrial environments. Renowned for its exceptional dynamic response and long-term stability, this model has become the gold standard for current monitoring in high-end power electronics. Optimized for high-current, high-noise, and wide-temperature applications, the LT1005-S delivers not only precise measurement but also zero-failure operation — making it a critical sensing node in smart manufacturing, renewable energy, and rail transportation systems.

     

    ‌LT1005-S ‌Core Features & Technical Advantages‌

    ‌±0.4% Ultra-High Accuracy‌ — Delivers laboratory-grade measurement reliability, meeting the stringent feedback demands of closed-loop control systems

    ‌<1 μs Ultra-Fast Response‌ — Captures IGBT switching transients, arc fluctuations, and motor startup surges without delay, eliminating control lag

    ‌DC to 150 kHz Wide Bandwidth‌ — One sensor replaces multiple units, compatible with DC, mains-frequency, and mid-to-high-frequency pulse applications

    ‌Zero Temperature Drift (-10°C to +85°C)‌ — Eliminates the need for external compensation circuits, reducing system complexity and maintenance costs

    ‌≥5.4 kV RMS High Isolation Voltage‌ — Ensures operator safety and withstands high-voltage transients, compliant with IEC 61010 standards

    ‌Closed-Loop EMI Immunity‌ — Maintains signal purity in high-electromagnetic-noise environments such as inverters, welders, and traction converters
