The KW2G Eco-Power meter enables the addition of up to seven expansion units, permitting users to gather data for several circuits at once. It provides simultaneous measurement of power and pulse input and is designed for mounting on DIN rails, making installation easy. The KW2G includes an RS485 interface (Modbus RTU/MEWTOCOL), enabling connection to other devices, and a USB port to connect to a PC for configuration. All values can be displayed graphically on a PC with KW Monitor software. —Panasonic
