Product Description
The CS3A P51 series are closed-loop (compensated) current sensors based on the Hall effect principle. They are designed for measuring DC, AC, and pulse currents with insulation between the primary and secondary sides. These sensors offer excellent linearity, accuracy, low temperature drift, and no insertion loss, making them ideal for various industrial applications.

Safety Precautions
Sensor usage must comply with IEC61010-1 standard. The sensor must be installed in electronic or electrical equipment that meets application standards and safety requirements as per the user manual. Be aware of electric shock hazards. During operation, certain parts of the sensor may carry dangerous voltages (e.g., primary busbar, power supply); neglecting this can lead to damage and serious danger. The sensor is a built-in device; ensure its conductive parts are inaccessible externally after installation. Protective covers or shields may be added if necessary. The main power supply must be disconnectable.
