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.
