Product Details
1.Product Description
Type DDSY3666 of Single-phase Electronic Prepayment Watt-hour Meter (hereafter referred to as watt-hour meter) adopts microelectronic technology to meter watt-hours and comply with the standard of GB/T17215.321-2008 and GB/T18460.3-2001. It employs the structure with complete shield and hermetic closure and uses advanced single-chip processor to collect, process and save data. It has these features: good anti-electromagnetic interference, low self-consuming and power saving, high precision and calibration-free, anti-electricity-theft, high overload and long life performance.

3.Funcions & Features
The watt-hour meter acquires voltage sampling signal by voltage divider, current sampling signal by current divider and voltage-current product signal by multiplier. Finally count impulse is generated through frequency transformation in which frequency is directly proportional to the voltage and current product.
Main features:
Application of computer management, power utilization after purchasing power;
limitation of maximal service power within the rated current range (prescribed by power supply department);
one card only for one watt-hour meter, no electricity interruption even with the loss of the card and ensuring the power continuation after the re-registration;
bilateral transmission of data and automatic power- cutting off to warn users to purchase power ;
automatic switch-off operation when the electric quantity hits zero ;
certain software design of anti-electricity-theft and so on .
