CSM’s new Split system for measuring current, voltage and power

Measurement technology manufacturer CSM has introduced a new measurement product composed of three modules for the high-frequency measurement of current, voltage and power in high-voltage power cables.

The High-Voltage Breakout Module Split (HV BM Split) is comprised of an HV SBM I open module for measuring busbars, an HV SBM I for measuring the power cables through a connection to cable glands and ring terminals, and the HV SAM 1.1 module, which acquires data and transmits it through a CAN bus. The HV SBM I can also be swapped for an HV SBM I C that connects high-voltage cables with an Amphenol PL300/PL500 connector system or an HV SBM I open shunt module that can be directly installed.

The system’s compactness was designed for EVs and hybrids with little installation space, production-intent vehicles and competitive vehicles. The split layout enables distributed installations such as in test vehicles, between vehicle components, through cable ducts, or inside components such as e-axles and batteries.

The HV BM Split is based on CSM’s HV Breakout Module, and is capable of measuring currents from 10 to 2,000 A and voltages up to 1,000 V. The measuring range is dimensioned up to 2,000 V.

The company says the HV SBM modules, excluding the HV SBM I open, are compliant with EN61010:1-2010 and are easily installed.
