Specifications

Prepaid Energy Meter
1)Good quality&best price
2)Simple structure,high reliability
3)Factory supply
4)Easy intallation

 

Introduction

DDSY794 Type Single-Phase Electronic Prepaid Energy Meter adopts microelectronic technology and comply with technical requirements for single phase electronic watt-hour meter stipulated in GB/T 17215.321-2008 and GB/T18460-2001. It apopts fully shielded, fully sealed structure and uses advance SCM processing systems for data collection, process and preservation...It also features good resistance to electromagnetic interference, low self-consumption of energy-saving, high accuracy, without calibration, burglar-proof electricity, high overload and long life etc...Meanwhile it provides fully functional managements software system of selling power.

Functions and features

1)Active single-phase electric power metering. No subject to adjust in terms of long working.
2)One card for only one user, well protected from forgery
3)One the remaining electric power quality is approching the alarming power quality, the digital tube should be lighted to remind user of timely purchasing;
4)One the electric consumption available is out, it should be cut-off automatically;
5)Protect from power theft, and record the information automatically;
6)Auto cut off for overload, Data-copying function make the electricity department easier to manage;
7)Adopt high reliability and long life electronic component, so the meter assume feature of high reliability and long life.
8)The IC card power selling control system has compelete function of power selling using spervision
