產品概述

       DTSY1693三相預(yu)付費(fei)電能表(射頻卡液晶顯示屏)采用微(wei)電子技術(shu)計量電能，產(chan)品符合GB／T17215-2008《1級和2級靜止(zhi)式(shi)交流有功(gong)電能表》和GB/T18460.3-2001《預(yu)付費(fei)電度表》標(biao)準。該(gai)電能表采用先進的(de)單片機系統進行數據采集、處理(li)(li)和保存(cun)，具有良好的(de)抗(kang)電磁(ci)干擾、低(di)功(gong)耗、防竊電、壽(shou)命(ming)長等特點。由于(yu)采用預(yu)付費(fei)方式(shi)，解決了電費(fei)拖欠問(wen)題，深得用電管理(li)(li)部門的(de)信賴。

功能特點

       ◆ 預付費(fei)(fei)功能：先(xian)交費(fei)(fei)后用電，欠費(fei)(fei)自動斷電，續費(fei)(fei)再用。

       ◆ 一卡通功能，可與水表、氣表、熱(re)量表實(shi)現卡通。

       ◆ 常(chang)顯(xian)報警提醒：可設置用戶的常(chang)顯(xian)報警值，當用戶電(dian)(dian)量剩(sheng)至常(chang)顯(xian)報警值時(shi)，電(dian)(dian)表(biao)顯(xian)示(shi)為常(chang)顯(xian)狀態．數(shu)碼管顯(xian)示(shi)表(biao)內(nei)剩(sheng)余電(dian)(dian)量。

       ◆ 斷電(dian)(dian)(dian)報警提醒可設(she)置用(yong)(yong)戶(hu)(hu)的(de)報警值(zhi)，當用(yong)(yong)戶(hu)(hu)電(dian)(dian)(dian)量剩至報警值(zhi)時，電(dian)(dian)(dian)表自動(dong)斷電(dian)(dian)(dian)，提醒用(yong)(yong)戶(hu)(hu)及時購電(dian)(dian)(dian)，斷電(dian)(dian)(dian)報警后，需(xu)再(zai)次插(cha)卡即可恢復(fu)供電(dian)(dian)(dian)。

       ◆ 零電(dian)(dian)(dian)(dian)量(liang)斷電(dian)(dian)(dian)(dian)：當電(dian)(dian)(dian)(dian)表內余量(liang)為(wei)零后．電(dian)(dian)(dian)(dian)表自動斷電(dian)(dian)(dian)(dian)，購電(dian)(dian)(dian)(dian)后插用戶(hu)卡(ka)方能恢(hui)復供電(dian)(dian)(dian)(dian)。

       ◆ 大液晶顯(xian)示(shi)屏顯(xian)示(shi)，插入用(yong)戶(hu)卡后顯(xian)示(shi)表內(nei)各(ge)項參數信(xin)息。

       ◆ 防電(dian)量(liang)囤(dun)積功(gong)能：當充(chong)值額(e)超出限定(ding)頡(jie)時．電(dian)表將不讀取(qu)卡中(zhong)的購電(dian)量(liang)，直到電(dian)表中(zhong)的剩(sheng)余電(dian)量(liang)與本(ben)次(ci)購電(dian)量(liang)之和小于限定(ding)額(e)時方可(ke)讀取(qu)。

       ◆ 使(shi)用邏輯加密卡和動態加密算(suan)法(fa)，保密性強(qiang)，卡內(nei)數據可保持10年以(yi)上。

       ◆ 采(cai)用大功(gong)(gong)率磁保持繼電器，功(gong)(gong)耗低，可靠(kao)性高。

       ◆ 超負荷(he)斷(duan)電(dian)功能：當用電(dian)負荷(he)超過設(she)定值時，電(dian)表自(zi)動斷(duan)電(dian)，負荷(he)降(jiang)低后電(dian)表自(zi)動恢(hui)復供(gong)電(dian)。
