  • Communication based on CANbus 2.0
  • Accuracy of ±0.4% of reading
  • Temperature range from -40°C to +105°C

Applications

The IVT-S current and voltage measurement sensor is an intelligent shunt-based plug-and-play measurement system. The module continuously measures current and is available in either 100A, 300A, 500A, 1000A or 2500A. The IVT-S modules offer guaranteed galvanic isolation up to 1000V making them suitable for high-voltage applications. There is also a temperature sensor within the module utilised for temperature calibration, ensuring optimised results across the whole temperature range.

The shunt-based measurement method uses a 16-bit analog-digital-converter (ADC) at a speed of up to 1kHz to transform the voltage drop into a digital signal. The communication is based on a CANbus 2.0a interface. A CAN description file (CAN-dbc) is available and supports fast system integration.

The ITV-S is offered as a modular system, with the options for 3 voltage monitoring channels and an additional CAN port to enable daisy-chaining.

Key features of the IVT-S Current & Voltage Measurement Sensor include:

  • Intelligent shunt-based current and voltage measurement sensor
  • 5 nominal current options: 100A, 300A, 500A, 1000A or 2500A
  • Optional 3-channel voltage measurement channels and extra CAN port
  • Optional extra CAN port for daisy-chain capabilities
  • Communication via CANbus 2.0a interface
  • Temperature range of -40°C to +105°C
  • Accuracy of ±0.4% of reading for current measurement
  • Accuracy of ±0.5% of reading for voltage measurement
  • Dielectric strength of 1000V
