IVT-S series // Current and voltage sensors for battery management systems

The IVT-S series are intelligent, digital voltage and current sensors, which were developed for the precise measurement of DC currents.

The IVT-S series is based on a modular principle and can be quickly adapted to customer applications. With a current measurement range of up to 2,500 A and a voltage measurement of up to 1,000 V, the IVT-S series is perfect for high-voltage applications or battery management systems.

At the same time, the IVT-S series also offers galvanic isolation of up to
1,000 volts. In addition to the current measurement, up to three measurement channels for high-current voltage measurement can be integrated through which the entire voltage of the battery stack as well as the entire monitoring of the intermediate circuit voltage and the relay functions occur.

Due to the programmable logic, additional functions are implemented, such as the temperature measurement of the busbars, the programmable overcurrent detection and other performance data.
