This state-of-the-art panel meter is designed for accurate measurement of the AC RMS current in three-phase systems. Although he is mainly used in electrical panels, this device can also be integrated in many other applications. The current transformer ratio can be set between 5/5A and 5000/5A via front panel buttons. Device have separate inputs for supply and measurement. The DA-0103 model allows both manual selection of the display channel and automatic scrolling.
