I. Product Overview

CYB series three-phase AC electric energy meter is a new generation of smart meters. This series of products is designed for the needs of power systems such as power systems, industrial and mining systems, public facilities, and intelligent buildings. Three-phase AC meters can be widely used in medium and low voltage distribution. Electrical systems, energy management systems, industrial automation and other fields are mainly used for the simultaneous measurement of single/three-phase voltage, current, frequency, active power, reactive power, power factor, and four-quadrant electrical energy in electrical circuits.
Second, product technical indicators
