Product Brief Of Introduction

The DDS7666 type electronic single-phase watt-hourperformance is in conformity with the technical requirementsmeter adopt exclusive use LSI, the device typifying newfor Single-phase Electronic Watt-hour Meter stipulated inperiphery component,simplestructure,high reliability,low power consumption,longlife etc,is suitable for  the single­phase AC active electric energywithratedfrequency of 50Hz.TheGB/T 7215.321-2008Class 1and 2 Static AC Active Watt-hourMeter standard.

Function and Features

- Measure active electric energy, do not need calibrate for  long-term operation;

- Adopt the special chip of measurement ADE7755;

- Adopt the latest oversea electricenergy special integration circuit, greatly improved dynamic working range of Meter;tomake the ability of actual overload up to over 10 times.

- Have good mistake linearity in the range of 5%Ib-lmax;

- Few peripherycomponents,simplestructure,low power  consumption;

- Adopt high reliability and long life electroniccomponents, so the Meter assume feature of high reliability and long life. 

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.
