LT 308-S6 current sensor is a closed-loop (compensated) current sensor based on the Hall principle, the primary and secondary sides are isolated, and are used to measure DC, AC and pulse currents. It features excellent accuracy, good linearity, low temperature drift, optimum response time, wide bandwidth, no insertion loss, strong anti-interference capability, and current overload capacity. It is mainly used in AC frequency conversion servo motors, DC motor traction static conversion, battery power, uninterruptible power supply (UPS), switch power supply (SMPS) and welding machine power supplies.
The LEM LT308‑S6 is a current sensor designed for measuring primary currents up to 300 A. It can be used for DC, AC, and pulsed current measurements in industrial applications.
The handbook lists key electrical parameters such as a 100 mA secondary output, 0.5 % accuracy at 25 °C, and a supply voltage of +15 V to +18 V. Mechanical data include mounting hole spacings of 84 mm (horizontal) and 75 mm (vertical) and an operating temperature range of –10 °C to +70 °C. This manual is written in Chinese.
