CM4A 1000 H11
Product Description
Product Overview
The CM4A H11 series is a closed-loop (compensated) current sensor based on the Hall effect, designed for measuring DC, AC, and pulse currents. It offers insulation between the primary and secondary sides, UL 94-V0 compliant materials, excellent linearity, accuracy, and low temperature drift without insertion loss. This sensor is suitable for various industrial applications including variable frequency drives, servo motors, UPS, DC motor drives, SMPS, welding machines, battery management, wind power converters, and test and measurement equipment.
