IVT-S

IVT-S

High-precision shunt-based current and voltage measuring device. Continuous current measurement covers a measuring range of up to +/- 2.500 A and can be expanded by up to 3 voltage measuring channels (nom. 1000 V).

IVT-3-Base

IVT 3 Base

The Base variant is based on a platform concept. This allows flexible adaptation to different applications. The IVT 3 Base was developed in accordance with ISO 26262 (Road vehicles – Functional safety).

IVT-3 pro U6

IVT 3 Pro

The Pro version is a further development of the IVT 3 Base and also features two-stage active insulation monitoring (IMD) and a choice of 3 or 6 voltage channels.

IVT 3 PRO: High precision current measurement device for active insulation monitoring

NEW: Insulation fault detection even at 0 V – before the relay closes

The current measurement device 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.

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
