Energy Probe Din

The power metering system

The energy probe is digital metering system that display and communicate major electrical parameters coming from power sources. To suit user requirements the range includes single-phase, three-phase four-wire capabilities. Total compliance with IEC 61036 standard, class 1

Operation

The digital meters are available in a panel mounted enclosure with a display to show the electrical parameters including the true rms values, current, voltage, power factor, phase angle, active/reactive energy, and frequency values. The simple menu-driven interface offers the interface before settings, configuration of selected communication options and adjustment of operating parameters.
