1.1 Introduction
This document provides operating, maintenance and installation instructions. The unit measures
and displays the characteristics of three phase four wires 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 60minutes.
The meter uses self-power supply module, the power is getting from L1.
This meter can be configured to work with a wide range of CTs, giving the unit a wide range of
operation. Built-in interfaces provide pulse and Modbus outputs. Configuration is password
protected.
The meter has RJ-12 terminal for current inputs. And voltage terminals, Pulse outputs and RS485
terminals are all plug-in types. The plug-in solution is user-friendly and mistake-free. It can also
save much labor work in wiring.
1.2 Unit Characteristics
The Unit can measure and display:
Line voltage and THD% (total harmonic distortion) of all phases
Line Frequency
Currents, Current demands and current THD% of all phases
Power, maximum power demand and power factor
Active energy imported and exported
Reactive energy imported and exported
The unit has password-protected set-up screens for:
Changing password
Demand Interval time
Reset for demand measurements
Pulse output duration
RS485 Communication
CT and PT setting
Two pulse output indicates real-time energy measurement. A Modbus output allows remote
monitoring from another display or a computer.
1.3 Current inputs
The unit can be configured to operate with CT ratio between primary current and secondary
current. The secondary current is 333mV（SDM630MCT-RJV only）. The secondary current is
100mA（SDM630MCT-RJA only）.
1.4 Modbus
This uses a RS485 port with Modbus RTU protocol to provide a means of remotely monitoring
and controlling the Unit.
Set-up screens are provided for setting up the RS485 port.
