The Honeywell CSCA0400A000B15B01 is a high-accuracy, closed-loop Hall-effect current sensor designed for precision measurement of AC/DC/pulsed currents up to ±400A. It provides a stable 4V analog output (±2V around a 2.5V midpoint) with exceptional linearity (±0.5% FS) and ultra-fast response (<1μs), making it ideal for: Motor drives & servo controls Renewable energy inverters (solar/wind) Industrial power converters Battery management systems (BMS)
