3 Product Description

3.1 Technical data overview

HV Breakout Modules (HV BM) are specifically designed for safe measurements on cables

carrying high voltage. Current and voltage are measured and the instantaneous power is

calculated online in the module.
The voltage is measured directly. The current measurement is done by using a shunt module,

which contains a differential amplifier as well as a temperature sensor and memory for cali-

bration data for automatic online temperature compensation.
The HV BM outputs the measured data at a data rate of up to 1 MHz via the EtherCAT®/ECAT

interface and at a data rate of up to 10 kHz via the additional CAN interface at the same time.

This allows fast data acquisition via Ethernet with simultaneous data recording via a CAN data

logger.
The HV BM is integrated into the HV power cables by feeding the cables through PG glands

into the inside of the module and connecting them there.
CSM provides shunt modules with different measurement ranges for HV BM 1.1 and HV BM 1.2.

The shunt modules are selected individually and are permanently mounted.

→ See HV BM datasheets for further information.
