Measuring current in tight environments

November 17, 2016 // By Christoph Hammerschmidt
With the ICD-A, components manufacturer Isabellenhütte (Dillenburg, Germany) is introducing a current measuring module that excels through its compact form factor.

The shunt-based ICD-A system has a sealed six-pole MCON connector, which is commonly used in the automotive industry. It protects the signal and power transmission from external influences. With transmission rates of up to 1 Mbit/s, the connection provides digitised data in CAN bus 2.0 format and ensures a high level of measurement precision for its users. The integrated microcontroller for the digitisation of the measurement values includes, among other features, an AC/DC converter, temperature sensing and voltage regulation.

The ICD-A also stands features an ultra-low energy consumption, which the sensor can also measure and supply independently – an advantage that is particularly important in the area of e-mobility. The product is available in three variations with different current levels: 100 A, 300 A and 500 A. All models have the same dimensions.

Alongside a version designed to suite automotive environments, the vendor also offers a version of the for industrial applications in the form of the ICD-C model. Both the ICD-A and the ICD-C boast a highly compact design. This makes them particularly suited to applications where space is tight in terms of assembly, because they are more than 50 per cent smaller than comparable products. Galvanic isolation was not used, as customer applications always have their own built-in galvanic isolation. This makes the ICD series one of the most compact product series in the ISAscale range.
