The BRH Series Open-Loop Hall-Effect Current Sensor is a precision current measurement device designed for use in new energy vehicles (NEVs), electric vehicle chargers (EVSE), motor drives, and Battery Management Systems (BMS). This sensor utilizes advanced Hall-effect technology to measure both direct current (DC) and alternating current (AC) with high accuracy and fast response time. With a wide bandwidth of DC to 250 kHz, it is capable of capturing rapid current fluctuations in high-frequency applications such as inverters, power converters, and regenerative braking systems—making it an essential component for efficient and safe power electronics control.
With its compact size and simple structure, the BRH series offers flexible installation options—including screw-mounting, clip-on, or PCB integration—allowing easy adaptation to various mechanical layouts. The fully isolated design ensures galvanic separation between the primary current path and secondary signal circuit, enhancing safety and reducing noise interference. The robust housing provides protection against moisture, dust, and vibration, meeting automotive-grade durability standards. Additionally, the product line includes multiple variants with different current ratings, dimensions, and mounting configurations, offering rich choices for diverse customer needs.
