The Electricity Meter SDM72D-M measures and displays the characteristics of three phase four wires (3p4w), including power, active energy, imported or exported. Energy is measured in kWh. In order to measure energy, the unit requires voltage and current inputs in addition to the supply required to power the product.
Eastron electricity meter supports up to 100A in direct connection. It saves the cost and avoids the trouble of connecting external CTs, which makes the unit cost-effective and easy to use. Built-in interface provides pulse and RS485 Modbus RTU outputs. Configuration is password protected.
