Specifications: The ASTK-600 series are performance-equivalent alternatives to the AACS773 series, offering identical high-performance specifications: 3.3V/5V supply, ±50A to ±200A ranges, 0.5% accuracy, 5000Vrms isolation, 250kHz bandwidth, 1.5µs response, and a wide -40°C to 125°C operating range. They share the same ultra-low 0.1mΩ primary resistance and are available in PFF, PSS, and SMT package options. Application Scenarios: Designed for the same demanding high-current sensing tasks, this series provides a reliable second source. It is well-suited for battery management system (BMS) current monitoring in electric vehicles and energy storage, for phase current measurement in industrial AC drives and robotics, and in high-power DC/DC converters, ensuring system designers have a robust and accurate current measurement solution with supply chain flexibility.
