概述 Application ()
DDS333型单相液晶显示电子式电能表采用专用大规模集成电路以SMT生产工艺制造的产品,具有防窃电、防反接、高准确度、高可靠性、高过载、功耗小、体积小和重量轻等特点。适用于计量额定频率为50Hz~60Hz单相交流有功电能。本产品各项技术性能符合GB/T17215.321-2008《1级f,132级静止式交流有功电能表》中的技术要求。

 

 

DDS333 type single—phase electronic watt—hour meter(LCD)adopts large—scale integrated circuit and SMT,with many obvious features like electric larceny prevention,reverse connection prevention,high accuracy,high reliability,high over load,low power consum ption,small volume,light weight,etc.It is suitable for measuring single—phase AC active energy of rated frequency 50Hz.Each per—formance of this product is in line with the technical requirements of GB/T17215.321-2008 Alternating Current Static Watt—hour Meters for Active Energy(Classes 1 and 2).

主要特点 Strncture ()

1、具有双向计量有功电能的功能,液晶计度器(LCD)显示;
2、具有RS-485及红外通讯(选配),可远程方便地抄出电能表的电量;
3、可设置或回抄:总电量、仪表常数、表地址、表密码等参数;
4、芯片内部具有看门狗系统,使数据更安全可靠,停电数据长久保存(连续停电可保存10年); 5、互相隔离的电源,分别为CPU、计量部分及RS485接口提供可靠的工作电源。
6、通讯规约按《多功能电能表通信规约Multi—function watt—hour meter communication protoc01》 DL/T645-1997中华人民共和国电力行业标准执行。

1、Measure the active energy in double directions,display by LCD;

2、S-485 and infrared communication interfaces(optional),which can take convenience for reading the energy of watt—hour meter;

3、Set or read back foIlowing parameters:total energy,instrument constant,meter address,meter password,etc..

4、Watchdog system in the chip,which can bring more safe and reliable data,and keep the data for a long time at power failure(keep for over ten years at continuous power failure)

5、Isolated power supplies are the working power supplies of CPU,measuring part and RS485 interface respectively 6、The communication protocol is based on DLT Electric Power Industry Standard:Multi— fLunction Watt—hoLur Meter Commu—nication Protocol.
