Beckhoff Automation LLC
The new ELM3002-0205 EtherCAT measurement terminal from Beckhoff delivers high-voltage measurement functionality for batteries, generators and motors. This feature-filled I/O terminal supports the four measurement ranges of ±60, ±120, ±500 and ±1,000 V, respectively, and is particularly suitable for applications in the fields of electric vehicles (EVs) and renewable energy.In the renewable energy market, the ELM3002-0205 supports, for example, efficiency increases for wind turbines via direct converter control. A prerequisite for this is voltage measurement in the 1,000 V range directly on the generator.
With the SCT5564 ring-type current transformer, Beckhoff offers a universal current-sensitive measurement system for AC and DC differential currents in conformance with the EN/IEC 62020-1 standard. Its use in machine monitoring ensures, among other things, increased system availability and minimized maintenance costs through the early detection of insulation faults. Crucial advantages and added value with PC-based controlFault currents can also occur during normal operation, e.g. due to the magnetizing of an electric motor during startup.
