These state-of-the-art panel meters are designed to accurately measure AC rms voltage and frequency in three-phase systems.
Although they are mainly used in electrical panels, these devices can also be integrated into many other applications.
The devices have separate inputs for power and measurement with a common neutral point.
Using the button on the front panel, you can select and read the phase-to-phase voltage (L1-L2, L2-L3, L3-L1) and phase-to-neutral voltage (L1-N, L2-N, L3-N). from the display. Automatic parameter scrolling is also available.
