Eastron SDM630-EV User manual

1. Introduction
The SDM630-EV V2 measures and displays the
characteristics of single phase two wires (1p2w),
three phase three wires (3p3w,) and three phase four
wires(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.
SDM630-EV V2 supports max. 100A direct connection,
saves the cost and avoid the trouble to connect external
CTs, giving the unit a cost-effective and easy operation.
Built-in interfaces provides pulse and RS485 Modbus RTU
outputs. Configuration is password protected.
