HV Split Acquisition Module 1.1 HV SAM 1.1

HV Split Acquisition Module 1.1

Acquisition module for single-phase current and voltage measurement in confined spaces

The HV Split Acquisition Module 1.1 (HV SAM 1.1) acquires the current and voltage values of HV Split Breakout Modules and also performs filtering, online calculation of RMS values and powers, and data output via EtherCAT® and CAN.

Highlights

  • Current and voltage measurement in HV applications in very confined spaces
    • Currents up to ±1,000 A (rated ), ±2,000 A (peak)
    • Voltages up to ±1,000 V (measurement range up to ±2,000 V)
  • Simultaneous EtherCAT® and CAN bus communication
  • Output of voltage, current and instantaneous power with up to 1 MHz measurement data rate each
  • Optional output of RMS values of current and voltage as well as active power, reactive power, apparent power and power factor via CAN bus

Desciption

By separating the sensor modules (HV SBM) and the HV SAM measurement module, the elements can be arranged spatially separately. While the sensor modules integrate almost perfectly into the HV cable routing due to their design, the measurement module does not have to be integrated directly into the measurement point.

The HV SBMs are connected to the measurement module via a HV-safe and shielded sensor cable. The sensor cable is also used to supply the measuring electronics in the shunt module of the HV SBM_I. As an alternative for the HV SBM_U, a HV-safe sensor cable for the voltage tap (HV+) can also be connected.

The HV SAM 1.1 measurement module provides the data acquisition, filtering and online calculation of RMS values and power. In addition, the encapsulated housing and the galvanic isolation between HV SBM and SAM ensure HV safety for users and components.

Currents are measured directly in the corresponding HV Split Breakout Modules (HV SBM_I, HV SBM_I open). Voltage measurement is performed in the HV SAM 1.1 based on the measured HV+ and HV- potentials (tap HV+ via HV SBM_U or sensor cable).

The measurement data is passed on via EtherCAT® and CAN bus.

Applications

Due to the separate design of sensor modules and measuring modules, the HV BM Split modules can be flexibly integrated into the measuring points.

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.
