Synchronized Acquisition of Power Data - Application Note

Product testing requires not only the conventional data acquisition of analog signals such as temperatures, pressures and flows, but also often the synchronized acquisition of power of data. This power data normally needs to be acquired in the form of AC values from the primary-side supply. Other relevant values include actual, apparent and idle power as well as cos phi, crest factor and TRMS for currents and voltages. For frequency converters, technicians also require a secondary-side measurement, ranging from DC values to high-frequency and distorted AC values.

Delphin Message devices are convenient solutions for these multi-value data acquisition applications. Single or 3-phase power measurement units can be connected to Delphin Message devices via a serial interface. This provides users with an optimal setup to synchronously acquire, monitor and evaluate all data in a single system.
