4-Channel Isolated Current Sensor Board
The 4-Channel Isolated Current Sensor Board is a compact, high-accuracy current measurement solution designed for power electronics, motor drives, renewable energy systems, battery management systems, and industrial automation applications. Based on the proven combination of the AMC1300 Isolation Amplifier and TLV9062 Precision Operational Amplifier, the board enables safe and reliable measurement of both AC and DC currents up to 30 A while maintaining complete electrical isolation between the power and control domains. The board incorporates an onboard isolated DC-DC converter, signal conditioning circuitry, reference voltage generation, and flexible output interfaces, making it ideal for real-time monitoring, protection, and closed-loop control applications.
With support for both single-ended and differential outputs, the sensor board can be directly interfaced with DSPs, microcontrollers, FPGAs, and data acquisition systems.
