Chapter 1. Introduction
SDM630MCT Mbus Series including models, SDM630MCT-MB & SDM630MCT-2T-MB.
The meter measures and displays the characteristics of single phase two wire (1p2w), 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 current transformers(CT).
The meter can be configured to work with a wide range of CTs with 1A/5A output, giving the unit a wide range of
operation.An M-Bus communication port is available on the meter for remote data transmission.
DM630MCT-2T-MB also offers a 2 tariff port for dual source power measurement.
This unit can be powered from a separate auxiliary AC power supply. Alternatively it can be powered from the
monitored supply, where appropriate.
