CSNS300F-003

Current Sensors Overview

The Honeywell CSNS300F-003 is a closed-loop, null-balance current sensor designed for high-accuracy measurement of AC, DC, and pulsed currents up to 300A. It features a single channel with bidirectional capability and provides complete electrical isolation between primary and secondary circuits. The device utilizes Hall effect technology with a response time of 500ns and operates within a frequency range of DC to 150kHz. It requires a 15V supply voltage and draws a maximum supply current of 160mA. Accuracy is rated at ±5% with a linearity of ±0.1%. The module supports base mounting and functions reliably in temperatures from -40°C to +85°C.
