Current measurement module may be used for monitoring both quiescent (sleep current) and operating current consumption of automotive electronic control units.
The Measurement range starts in the range of microamperes with a resolution of 125nA and goes up to 190A.
Short Current peaks of 300A are allowed.
The measurement range is subdivided into 7 sub-ranges. By means of fast electronic switches the module selects the appropriate measurement sub-range, depending on the actual current consumption of the device under test.
Voltage drop is limited to approx. 1V for only a few microseconds when current steps occur from several uA to 100A.
The operation voltage of the electronic devices under test may be up to 150VDC. Thus, application is possible for 12V, 24V and 42V vehicle electrical systems both in test systems and in real cars.
