This document describes the features and characteristics of the LT 308-S7 current sensor, including its application for measuring DC, AC, and pulse currents, and its excellent accuracy, low temperature drift, optimal response time, and wide bandwidth.
The LT308‑S7 is a Hall‑effect current sensor designed to measure primary currents up to 300 A with a secondary output of 150 mA. It features a 1:2000 turns ratio and is suitable for AC applications up to 50 Hz.
Key specifications include an accuracy of 0.5 %, linearity better than 0.1 %, a bandwidth of 100 kHz (3 dB), and an operating temperature range of –10 °C to +70 °C. The sensor is housed in a compact package with a 20 mm primary aperture and a MOLEX secondary connector. This manual is written in Chinese.
