Bourns® Digital DC Current Sensors offer superior accuracy, stability and electrical isolation with the advantage of high precision over a wide operating temperature range.

Bourns, a leading global manufacturer of electronic components for power, protection and sensing solutions, is pleased to introduce the SSD Digital Series of current sensors, which includes innovatively designed digital DC shunt-based current sensors that offer superior accuracy, stability and galvanic isolation over a wide operating temperature range from -40 °C to +115 °C. These small, highly integrated digital system-in-package (SiP) devices are ideally suited for a wide variety of applications. These small, highly integrated digital system-in-package (SiP) devices are ideally suited for a variety of battery-related current sensing applications, including large-scale energy storage banks, renewable energy generation infrastructures, industrial motor drives, building automation systems and electric vehicle charging stations.

The Bourns® SSD features a 16-bit automotive-grade microcontroller unit (MCU) that provides ±0.1% full-scale accuracy. The internal 24-bit analogue-to-digital converter (ADC) offers plug-and-play simplicity, helping to significantly simplify the implementation design process and enabling engineers to quickly add high-precision current measurements to their latest designs or retrofit them into existing designs. These shunt-based current sensors also eliminate the need for periodic device calibration while providing highly accurate measurements that help make more efficient use of power. The series is available in two models: an RS-485 series interface model, which can also be configured for MODBUS RTU, and a customisable CANbus model.
