The SSD-250A-R from Bourns is a 24-bit Isolated Shunt Current Sensor that has been designed for high-precision DC measurements. This current sensor requires a supply voltage of 5-60 V and an input current from -250 A to +250 A. It has an accuracy of ±0.1%. This sensor supports both RS485 and MODBUS protocols allowing flexible integration into various systems. It provides a reinforced galvanic isolation rated at 1500 V (DC) that ensures safe operation in high-voltage environments. This sensor incorporates a 16-bit microcontroller capable of operating at temperatures up to +150°C. It includes a 24-bit analog-to-digital converter (ADC) with buffered analog inputs for superior measurement accuracy and error correction code (ECC) flash memory with auto-correction for single-bit errors.
This RoHS-compliant current sensor includes advanced error detection with internal and external cyclic redundancy check (CRC) mechanisms and ensures stable performance with non-linear temperature compensation. It is available in a screw-mount package that measures 3 x 16.4 mm and is ideal for EV charging stations, battery systems, renewable energy, and motor drive applications.
