Additional Details

The HAH1DRW1200-S current transducer operates based on the Hall effect. The primary current flowing through the transducer generates a magnetic field, which is sensed by a Hall sensor. The output signal is proportional to the primary current and is galvanically isolated from the primary circuit. The datasheet provides detailed specifications on accuracy, linearity, bandwidth, and temperature drift. The typical supply voltage is +5V or +12V, depending on the specific model. The output signal is typically a voltage or current that is proportional to the measured current. External components, such as filtering capacitors and termination resistors, may be required for optimal performance. The operating temperature range is typically -40°C to +85°C. The isolation voltage rating ensures that the primary and secondary circuits are galvanically isolated, providing protection against high voltage transients. The transducer is designed to meet relevant safety standards and certifications. It is commonly used in applications where accurate and reliable current measurement is critical for control, monitoring, and protection purposes. Detailed mechanical drawings and mounting instructions are available in the product datasheet.
