The NSM211x series of high-bandwidth integrated current sensors from Naxinwei are primarily based on the Hall effect principle, using isolation to convert currents within ±200A into linear voltage outputs. They are suitable for various isolated current sampling applications, such as PV input side of photovoltaic string inverters, current detection for MPPT (Maximum Power Point Tracking), and AC side current detection. They are also used for busbar current and phase current sampling in industrial frequency converters, UPS and server power supplies, isolated current sampling in charging piles, current detection for automotive OBC PFC, resonant cavity current detection, and more.
