IVT 3 Pro – Active insulation monitoring
Insulation fault detection even at 0 V – before the relay closes
The IVT 3 Pro was specially developed for monitoring high-voltage systems in commercial vehicles, agricultural machinery, and construction equipment.
With the IVT 3 Pro, you get a 3-in-1 sensor that combines precise current measurement, HV voltage measurement, and two-stage active insulation monitoring in a single CAN module.
Product-highlights
- Nominal current range: +/- 1.000 A
- Accuracy: 0,4 % + 100 mA
- Temperature range: −40 °C to +125 °C
- Galvanic isolation: up to 1.000 V*
- CAN 2.0 a/b communication
- 3 or 6 voltage channels
- Power supply: 12 V or 24 V
- Two-stage active insulation monitoring (IMD)
- Temperature measurement directly at the shunt hotspot
- Optional sleep mode
- Detection of an insulation fault on the battery and vehicle in <5s
- Increased system security in PDUs, BDUs, BJBs, and charging boxes
Why you should choose the IVT 3 Pro
- Simplified system architecture
One sensor provides current, voltage, and insulation – via one CAN interface. - Fully integratable for functional safety
Shunt-based current measurement according to ASIL C and 3 or 6 HV voltage inputs according to ASIL B – tailored to safety concepts and OEM requirements. - Precise values for your algorithms
Advanced diagnostics via unified diagnostic service (UDS) provide highly accurate current and voltage data for BMS, SoC/SoH, and diagnostic functions. - Increased electrical safety
Thanks to the detection of insulation faults even at 0 V, you get clear and stable measurement results — even in 0 V phases of the HV architecture.
Ideal for these applications
Where safety, robustness, and precise HV measurement are crucial
- Precise measurement in power distribution systems
- Precise measurement in vehicles with fuel cells
- Precise measurement for stationary storage systems
