CSHV400A-001

CSHV400A-001 is a CSHV series open loop current sensor that uses hall-effect sensing and patented Honeywell technology to bring the best combination of performance and reliability for current sensing applications. It is non-intrusive and electrically isolated from the monitored circuit. This ensures a simple sensing method. The CSHV series is AEC-Q100 qualified to meet higher quality and reliability. For motor control applications, the current measurement is directly proportional to the motor torque. Current measurement can also be used to determine the speed at which the motor is turning. Such speed information can be calculated by understanding how the control algorithm affects the current level. It is ideal for current measurement for battery management systems in electrified vehicles (EV, HEV, PHEV, BEV), current leakage detection and fault isolation in battery charging systems, current measurement in energy storage systems, fault detection in heavy industrial equipment.
