Product Overview

The Honeywell CSNF661 Closed Loop Current Sensor belongs to the closed-loop current sensor series, utilizing magnetoresistive or Hall-effect principles with zero magnetic flux balance technology. It supports AC/DC, and impulse current measurement, featuring high precision, wide range, and fast response. Its compact design and industrial temperature range make it ideal for industrial control, power systems, and battery management, providing reliable current monitoring and overload protection.

Key Features

• Wide Current Range: Measures ±100A AC/DC and impulse currents, suitable for diverse industrial and consumer electronics applications.
• High Precision & Stability: Achieves ±0.5% accuracy via zero-flux feedback system, with built-in temperature compensation for consistent performance across all temperatures.
• Rapid Response: Features a response time of <1μs, enabling real-time capture of current fluctuations for dynamic monitoring and quick protection.
• Electrical Isolation: High-level isolation between primary and secondary circuits ensures interference resistance and safety compliance (CE, UL certified).
• Compact & Robust Design: Supports PCB or panel mounting, operates from -40°C to +85°C, and adapts to harsh industrial environments.
