The INA226-1A is a fully isolated, high-precision current, voltage, and power measurement unit suitable for measuring DC 0-30V voltage and a maximum current of 1A. It supports simultaneous voltage and current measurement. Users can read key parameters such as current, voltage, and power through the I2C communication interface, and the unit supports multiple control platforms. It also integrates an isolated power supply module and I2C signal isolator to achieve comprehensive electrical isolation between the measurement end and the main control end. It also has a self-resetting fuse that will automatically blow when the current range is exceeded, which can effectively ensure the safety of equipment and personnel and improve the system's anti-interference ability. It is suitable for various electrical parameter collection application scenarios such as power management, battery monitoring, and industrial safety.
