These state-of-the-art panel meters are designed for accurate measurement of the AC RMS voltage, AC RMS current, frequency, active power and power factor in single-phase systems. Although they are mainly used in electrical panels , these devices 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. Devices have separate inputs for supply and measurement. The unit allows both manual selection of the display channel and automatic scrolling. WE DO NOT SHIP THIS DATAKOM PRODUCT TO USA AND CANADA
