Introduction

The SDM72CT-M-2T is digital three phase 4 wire energy meter with a white back-lighted LCD screen for perfect

reading. The unit measures and displays the characteristics of three phase four wires(3p4w) supply, including

voltage, frequency, current, power ,active and reactive energy, imported or exported. Energy is measured in terms

of kWh, kVArh. The requisite current input(s) are obtained via current transformers(CT).

This meter can be configured to work with a wide range of CTs, giving the unit a wide range of operation. Built-in

interfaces provides pulse and RS485 Modbus RTU outputs. Configuration is password protected
