NEW! – IVT 3.0 / IVT 3.0 Pro – The next generation in sensing (coming soon, B samples available)

A new level of compact high precision smart sensing, built on a platform
that allows the custom addition of functional components to suit many different use cases. The Pro version supports insulation resistance monitoring and 3 or 6 channels voltage measurement. The IVT 3.0 Series is developed according to ISO 26262:2018 and is ASIL-rated for EV/automotive applications.

Sample applications include:

  • Hybrid and full electric vehicle drives
  • Stationary energy storage systems
  • Uninterruptable power supply (UPS) systems
  • Battery and storage based applications
  • Industrial Applications

Product highlights:

  • Highly accurate shunt-based current measuring system with active temperature compensation over lifetime
  • 3 or 6 voltage measurement channels (PRO version)
  • Active insulation monitoring (PRO version)
  • ASIL C on current sensing
  • ASIL B on voltage sensing and insulation monitoring
  • Secondary analog current sensing channel (optional)
  • Nominal current measurement range = ±1.000A
  • Extended measurement range: 4000A
  • Initial Accuracy = 0,1 % of rdg. + 0,005% of range at room temperature
  • Total Accuracy = 0,4 % of rdg. + 0,005% of range (over whole temperature range -40°C up to 125°C)
  • Galvanic insulation 1.000V
  • CAN 2.0B (CAN FD or SAE J1939 optional)
  • Temperature measurement
  • Supply voltage 12V-24V
