The Power Monitor from Weidmüller measures and records the relevant electrical parameters of machines and systems and forms the basis of an energy management system. The device measures and visualizes the parameters current, voltage, power, active factor, apparent and reactive power for each connected phase as well as in the total line. Thanks to one percent accuracy and a display update every 0.1 s, the accuracy requirements of IEC 62053-21 are met. Currents from 1 mA are recorded, for example from devices in stand-by mode. The measured values appear on the four-line, backlit LC display. The measuring device is equipped with IP51 protection on the front. It integrates an RS485 interface and a USB port for communication. Softkeys enable safe navigation in the menu.
