Energy Meter Eastron Modbus single-phase and three-phase

Smart meter for single- and three-phase electrical systems

The unit measures and displays the characteristics of single-phase two-wire (1p2w), three-phase three-wire (3p3w) and three-phase four-wire (3p4w) power supplies, including voltages, frequencies, currents, powers, active and reactive energies, imported or exported. Energy is measured in kWh, kVArh. Maximum demand current can be measured over predefined periods of up to 60 minutes. To measure energy, the device requires voltage and current inputs in addition to the power supply needed to power the product.

SDM630Modbus supports max. 100A direct connection, saving cost and avoiding the problems of connecting external CTs, giving the device simple, economical operation. Integrated interfaces provide pulse and RS485 Modbus RTU outputs.
