Delivering the advantages of digital compatibility, new current sensors feature superior accuracy, stability and electrical isolation
RIVERSIDE, Calif., November 3, 2025 - Bourns, Inc., a leading manufacturer and supplier of electronic components for power, protection, and sensing solutions, today announced its SSD-1000A Digital Current Sensor Series. Highly integrated and compact, Bourns® new shunt-based current sensors feature a current range from 100 A to 1000 A and offer exceptional accuracy, stability and electrical isolation in a wide -40° C to +115° C operating temperature range. These features are required in a broad range of applications including battery management systems, renewable energy, motor drives, EV charging stations and other designs that are required to operate in certain harsh environments..
The series’ 16-bit Microcontroller Unit (MCU) delivers ±0.1 percent full-scale accuracy that contributes to more efficient use of power. The internal 24-bit Analog-to-Digital Converter (ADC) provides plug-and-play simplicity, helping to significantly streamline implementation. This enables engineers to quickly add high-accuracy current measurement into their latest designs or retrofit existing ones. There are two SSD-1000A series models: an RS-485 serial interface model, which can also be configured as MODBUS RTU, and a customizable CANbus model. To further help simplify circuit design, Bourns is also offering an internal 120 ohm termination resistor as an optional feature with this new series.
The Bourns® SSD-1000A Digital Current Sensor Series is available now and is RoHS* compliant. For more detailed product information, please see: bourns.com/products/sensors/current-sensors.
