HV Breakout Modules
The HV Breakout Modules (BM) have been specifically designed for safe measurement applications on cables carrying high voltage. Current and voltage are evaluated and the power calculated online in the module.
The voltage is measured directly. Current measurement is performed by a shunt module that includes a differential amplifier, a temperature sensor and a memory chip for calibration data for automatic online temperature compensation.
The HV BM outputs the measured data with a maximum data rate of up to 1 MHz via EtherCAT® interface and simultaneously with a data rate of up to 10 kHz via the additional CAN interface. This allows a high speed data acquisition via Ethernet and at the same time data recording via CAN data logger.
The HV BM is to be inserted into the HV power cables by feeding the cables through PG cable glands into the module and connecting them there.
For the HV BM 1.1 und 1.2 CSM offers shunt modules with different measurement ranges. The shunt modules are selected seperately and are permanently installed.
