These state-of-the-art panel meters are designed for accurate measurement of the AC RMS voltages and frequency in threephase systems. Although they are mainly used in electrical panels , these devices can also be integrated in many other applications.
Devices have separate inputs for supply and measurement with common neutral point. Through front panel buttons, phase–tophase (L1-L2, L2-L3, L3-L1) and phase-toneutral (L1-N, L2-N, L3-N) voltages and frequency can be selected and read from the display. Automatic parameter scroll is also available
