Bourns SSD Shunt Current Sensors

Bourns SSD Shunt Current Sensors are 24-bit isolated sensors with CANbus or RS-485/MODBUS interface. These sensors feature a 100A to 1000A current rating (2kA to 20kA peak), 1500VDC reinforced galvanic isolation, and ECC flash memory with autocorrect single-bit errors. The SSD sensors also feature a 0.1% tolerance, a 16-bit 150°C microcontroller, and internal and external CRC data error detection. These sensors include advanced non-linear temperature compensation for battery systems, motor drives, renewable energy, and EV charging station applications.
