Product Brief Of Introduction

MODEL DDS7666 single phase enectronic active energy meter is a kind of new style single phase two wire active energy meter, it adopt micrelectronics technique, and imported large scale integrate circuit, use advanced technique of digital and SMT techniques, ects. The meter completely accord with relevant technical requirements of class 1 single phase active energy meter stipulated in international standard IEC62053-21. It can accurately and directly measure 50HZ or 60HZ active energy comsumption from single phase AC electricity net, it is used for setting indoor or outdoor, and it can display total energy consumption by step type impulse register. It has following features: good reliablity, small volume, light weight, specious nice appearance, convenient installation, ect.

Function and Features

-Standard configuration 5+1 digits display(99999.1kWH)by step motor and pulse machinery counter. May select 6+1 digits display-Configuration one port of pulse output passive(polarity).

- Two led instructions power state and signal of power impulse.-Automatic detect the direction of the trend of load current. And onely yellow led display when working,this is meaning the load current reverse.

-Single direction single component measure single phase two wire active power consumption. It is nothing with direction of the trend of load current. Complying with standrad IEC62053-21.Direct connect and use, there are two types you may select. Standard configuration type A connection, may select type B connection.

-The power dissipation is less than 0.5w when power supply 120v, and power dissiptaion less than 0.8w,circuit dissipation less than 0.5VA while power supply 120V, which is much higher standard than IEC 62053-21.

-Standard configuration extended terminals cover, may select short terminals cover, in order to protect to use electricity safely

MAIN TECHNICAL DATA 

The meter is highly precise, highly sensitive. Highly reliable wide load rang, low power loss, the power in double directions. Both positive and negative work can be measured in accumulated same direction. So it can prevent any power steeling, such as reverse steeling. live-earth wire steeling, short circuit and so on.
