HV Breakout Module 3.1 
The HV Breakout Module (BM) Type 3.1 is suitable for three-phase current, voltage and power measurement at three-phase charging stations with HV voltage carrying cables with currents up to ±32 A.
The HV BM is inserted into the typically 5-wire HV cable by feeding the cable through cable glands into the interior of the module and connecting it there using Phoenix terminals. The three-phase measurement with only one measuring device offers enormous cost and space advantages.
The three currents and voltages are measured with reference to the neutral conductor and this measuring circuit (3P4W) is already applied in the module.
The HV BM 3.1 outputs the measurement data with a maximum data rate of up to 500 kHz via the EtherCAT® interface and simultaneously with a data rate of up to 5 kHz via the additional CAN interface. This enables fast data acquisition via Ethernet with simultaneous data recording via CAN.
