PLC power measurement terminal for direct measurement of AC currents

The standard parameters for detecting energy and performance data are preset to facilitate easy startup.. For many use cases, voltages up to 400 V/690 V and phase currents and a neutral conductor current of up to 5 A can be directly connected without a transducer. If this is not sufficient, external transducers can be added to expand the measuring ranges. The measured values can be used to calculate values such as the active power, reactive power and apparent power and energy. In addition, S0 pulses are available. The grid quality can be analyzed based on the harmonics that are determined (THD). This makes it easy to localize disturbance sources.
