Additional Details

The CAS15-NP utilizes a closed-loop (compensated) technology to achieve high accuracy and linearity. In a closed-loop system, the magnetic field generated by the primary current is compensated by a secondary current, resulting in a more accurate measurement. The galvanic isolation between the primary and secondary circuits provides safety and prevents ground loops. The device operates over a wide temperature range, ensuring stable performance in various environmental conditions. It's designed for ease of installation and integration into existing systems. The voltage output is proportional to the measured current, making it easy to interface with analog-to-digital converters (ADCs) and other measurement devices. The CAS15-NP is commonly used for monitoring and controlling currents in power electronics applications. The transducer is known for its robustness and reliability. The accuracy specification often includes a combination of offset, gain, and linearity errors. The current transducer provides essential information for optimizing system performance and protecting sensitive equipment from damage.
