Product Description
DTSD1352-4S series DIN-rail type multi-circuit power meter is mainly used for the full electric parameter measurement of multiple circuits, and can be connected to the current input of 4 three-phase circuits or 12 single-phase circuits at the same time. It can measure parameters such as voltage and current, power, power factor, phase angle, unbalance, and harmonics.
