SDM630MCT-RC is Eastron's new-generation three-phase smart energy meter.
The meter measures and displays the characteristics of single phase two wire (1p2w), single phase three wire (1p3w), three phase three wire (3p3w) and three phase four wire (3p4w) supplies, including voltage, frequency, current, power, active and reactive energy, imported or exported. Energy is measured in terms of kWh, kvarh. Maximum demand current can be measured over preset periods of up to 60 minutes. In order to measure energy, the unit requires voltage and current inputs in addition to the supply required to power the product. The requisite current input(s) are obtained via Rogowski coils.
The meter can be configured to work with Rogowski coils without integrator. The ratio of connected Rogowski coils should be standard 100mV/kA. An RS485 communication port is available on the meter for remote data transmission.
This unit can be powered from a separate auxiliary AC power supply. Alternatively it can be powered from the monitored supply, where appropriate.
It has been assessed and certified as meeting the requirements of EU Directive 2014/32/EU.
