Single Phase Prepaid Energy Meter with IC card DDSY480

1.Application

It is a new generation product that is developed by our company,adopting the newest international micro technique and the newest international electronic currency-IC card as purchasing electricity media.

This meter has many functions such as electrical energy calculation ,load control and 

mangement of user informations, etc.,specially for currently,this meter is the best use for 

solve charge question.

The product can be installed in the electric meter box,indoor or outdoor,the ambient 

temperature is -25'C - +60'C.The relative humidity is less than 85%.

Each of the capabilities index of product complies with IEC62053-21 static watt-hour meter international standard

And the meter confirmed by CE and ISO9001-2000 standards.

2.Working principle

+ Active Single phase electric power metering,no subject to adjust in terms of long working

+ Each user(meter) responds to one card,well protect form forgery

+ Once the remaining electric power quality is approaching the alarming power quality,the digital tube should be lighted to remind user of timely purchasing.

+ Once the electric consumption available is out,it should be auto cut-off

+ Protect from power theft,and recording the information automatically

+ Auto cut-off for overload

+ Data-copying function make the electricity department eariser to manage.

+ The meter has the feature of long using life & high-reliable

+ The IC card power selling control system has the function as power selling and using control

+ Expansible RS485
