SDM630Mbus 3 Phase Mbus Multifunction Mbus Power Analyzer

Product Overview

Description

 

Brief Introduction

The unit 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.

 

SDM630Modbus 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.

*Multi-tariff

 

This unit provide option for multi tariff. max. tariff can be programmed to 4 , and 10 period. (optional)

 

 

 

Communications

 

The meter is an ideal choice as slave meter in AMR system. it provides both Pulse output and RS485 port.

 

 

 

Pulse Output

 

There are 2 pulse output, one is for active energy, and constant is 1000imp/kWh, another one is configurable. 

 

the user can set the pulse output type, pulse constant, and pulse weight. 

 

Pulse type: total kWh, total kVarh, import kWh, export kWh, import kVarh, export kVarh

 

Pulse constant: 100/10/1/0.1/0.01/0.001kWh(kVarh)/imp

 

Pulse weight: 200/100/60mS

 

 

 

RS485 Port

 

There are one RS485 port on the meter, which can be used for remote communication or monitoring.
