The HV Split Breakout Modules (HV SBM_I/U 10 A / 50 A) have been designed for safe and precise current and voltage measurement. They measure directly in HV+ and HV- power cables that run between tightly installed components and have a small inner conductor diameter of up to 6 mm2.
The HV Split Breakout SBM_I/U measure single-phase currents via a shunt module that includes the measurement shunt, the temperature sensor for automatic temperature compensation and the sensor electronics. The measurement directly in the inner conductors and the encapsulated housing ensure precise measurement results.
The voltage (HV+ and HV-) is also tapped in the module. The voltage measurement takes place in the HV SAM (HV split acquisition module).
The HV cables are fed into the housing through cable glands and connected inside via Phoenix terminals.
The HV SBM_I//U is connected to the HV SAM measurement module via a plug-in connection using two HV-safe and shielded sensor cables which are permanently installed in the sensor module.

The HV SBM_I/U can be used to reliably measure small currents and voltages at e.g. auxiliary consumers in the HV environment.
With the measurement data obtained from the HV BM Split Modules and the eMobilityAnalyzer from the Vector CSM E-Mobility Measurement System a variety of analyses in real time can be performed: Inverter and powertrain efficiency calculations, e-motor power analysis, harmonic analysis, PWM analysis, ripple analysis and many more.
