## CSNV500 SERIES 

## **Closed Loop Current Sensors** 

## DESCRIPTION 

The CSNV500 Series are Hall-effect, closed loop current sensors that use Honeywell patented technology to bring an enhanced combination of performance and reliability. They are non-intrusive and electrically isolated from the monitored circuit. This can ensure a simple and reliable structure without loss of power to the monitored circuit. The CSNV500 Series are rated for a primary current measurement range of ±500 A dc. They are calibrated and temperature compensated for improved accuracy using multi-point temperature characterization. 

## DIAGNOSTIC FUNCTIONALITY/ CAN OUTPUT 

The CAN output of the CSNV500 Series provides fault detection and communication capability. Also, the digital CAN communication is immune to electrical interference. Examples of sensor and host system faults include: 

- Sensor fault 

- Supply voltage over range 

- Supply voltage under range 

## CUSTOMIZATION 

The CSNV500 Series may be customized to better meet application needs. Solutions may be tailored to exact specifications for improved time to market, lower total system costs and enhanced reliability. For technical assistance, we provide global engineering and service support for your needs. 

## DIFFERENTIATION 

- **Accuracy:** Multi-point temperature characterization and calibration for improved accuracy over temperature range 

- **Magnetic immunity:** Closed loop configuration and optimized magnetic circuit allow for enhanced performance in diverse magnetic environments 

- **Flexible:** Customizable on-board firmware to meet specific application requirements 

## VALUE TO CUSTOMERS 

- **Accurate:** Designed to enable precise battery state measurement for improved user experience 

- **Ease of use:** Magnetic immunity allows for easy integration into different magnetic environments 

- **Easy system integration:** CAN communication is transmitted using international road vehicle standard ISO 11898. CAN 2.0A is the default protocol 

## INDUSTRIAL APPLICATIONS 

- Current measurement for battery management systems in electrified vehicles (EV, HEV, PHEV, BEV) 

- Current leakage detection and fault isolation in charging systems 

- Current measurement in energy storage systems 

- Fault detection in heavy industrial equipment 

## FEATURES 

- Active closed loop current sensing using Hall-effect technology 

- Utilizes proprietary Honeywell technology for temperature compensation 

- High accuracy and low temperature drift 

- Operating temperature of -40°C to 85°C [-40°F to 185°F] 

- Digital output: CAN bus output with selectable ID 

- Internal diagnostic function 

- Different configuration options: Mounting type, baud rate, CAN ID 

- UL, CE, and UKCA certifications; REACH and RoHS compliant
