The CW-425 facilitates measuring working currents in the 0 µA to 30 A range. The wide measurement range is made possible by two different measuring shunts, which thanks to a switching delay of less than 2 µS ensures it is possible to switch from one to the other virtually seamlessly. The measured value of the CW-425 is issued via CAN bus; as a consequence, it can easily be integrated in different measuring chains. The field of application of the CW-425 is, for example, automated measurement of no-load and working currents of control units on HiL test benches.
