SIRC devices are high quality multi-functional small chips that can output power, power factor, harmonics, and frequency in real time.
The small size of SIRC device allows it to be installed in places where conventional sensors could not be installed, providing a detailed power saving solution in a wide range of applications.
In addition, SIRC is developing new functions using multiplication functions, such as ultrasonic measurement, medical applications, and information processing devices.
In the field of IoT, by disseminating SIRC devices as key devices, it will be possible for other businesses to develop highly value-added products and services by connecting things with the Internet which will ultimately contribute to create new industries.
With SIRC devices, we strive to create a safer, smarter and more energy efficient and eco-friendly world.
Ultra-compact, low power consumption with sensor and multiplication functions.
Patented worldwide for the sensor itself being able to operate physical multiplication.
- Revolutionary compact, lightweight, low consumption
- Accurately measuring AC, DC, real and apparent power.
