CR1A H00 SERIES Current Sensor

The CR1A H00 SERIES is a closed-loop Hall Effect current sensor designed for the electronic measurement of DC, AC, and pulsed currents. It provides galvanic separation between the primary and secondary circuits, ensuring safety and reliability. Key features include very good linearity, high accuracy, low offset drift over temperature, and no insertion loss. This sensor is ideal for various applications such as AC variable speed and servo motor drives, Uninterruptible Power Supplies (UPS), static converters, Switch Mode Power Supplies (SMPS), power supplies for welding, battery management, wind energy inverters, and test and detection devices.
