FHDCT-055 High-precision and low-error current transformer

The FHDCT-055 High-precision and low-error current transformer is a high-performance product designed for high-precision current measurement needs in industry, medical, and laboratory applications. The product uses advanced micro-flux technology, combined with a dual-coil structure and a passive error compensation method to ensure high-precision performance within the allowable error range, with an accuracy of up to 0.02%. The FHDCT-055 current transformer has extremely high linearity and low DC offset characteristics, as well as low temperature drift and low insertion loss, which enables it to perform well within the dynamic current range. In addition, the product has strong anti-interference capabilities and can operate stably in harsh environments, making it suitable for a variety of application scenarios, including high-precision current feedback units, energy measurement equipment, and new energy vehicle electronic equipment. The FHDCT-055 current transformer supports wide-band (up to 800kHz) measurements and provides a standard 9-pin D-Sub interface and LED status indicator for easy user connection and monitoring. Its compact design and flexible installation methods enable it to be easily integrated into existing electrical systems while meeting the requirements of the IEC 62053-21 standard. Whether in terms of accuracy, stability or flexibility, FHDCT-055 is a trustworthy high-precision current transformer that provides users with measurement performance and a reliable usage experience.
