Product Overview
The CR1V PB05 series current sensor, model CR1V 75 PB05, is a closed-loop Hall effect sensor designed for measuring DC, AC, and pulse currents. It features isolation between the primary and secondary sides, UL 94-V0 compliant materials, excellent linearity, accuracy, and low temperature drift, with no insertion loss. This sensor is suitable for various industrial applications including AC variable frequency drives, servo motors, UPS, DC motor drives, SMPS, welding machine power supplies, battery management, photovoltaic inverters, and modular power supplies. Safety precautions must be followed as per IEC 61800-5-1 standards, ensuring proper installation and protection against hazardous voltages.
