KW7M Eco-POWER METER DIN Type All functions needed for power measurement now in a DIN type! Dedicated CT 22.5mm 1 Save Space and Install More Easily 3 1 Can be installed in control panels Supports DIN specification (22.5 mm) and is thinnest in industry with a display (Based on our investigation). Installable on DIN rail 2 Can be used with compact dedicated Current Transformer (CT). 2 1 Also supports 5 A CT of secondary current input. * When inputting a 5 A secondary current, use 2-stage configuration by combining with a dedicated CT. 2 Support for 400 V AC * Use with external voltage transformer (VT) 4 Power Measurement Function 1 Instantaneous electrical power display 2 Integrated electrical energy display 3 Each phase voltage and current display Multiple Inputs Supports Networking 1 An RS485 communications port comes standard 2 Comes with MEWTOCOL/Modbus (RTU). * Modbus Protocol is a communications protocol developed for PLCs by Modicon Inc. 3 Pulse output is standard function.
