預付(fu)費(fei)電(dian)(dian)(dian)表采用先(xian)購電(dian)(dian)(dian)再用電(dian)(dian)(dian)，到(dao)零斷電(dian)(dian)(dian)的模式，解決了以往收電(dian)(dian)(dian)費(fei)難的問題。并(bing)(bing)且(qie)，由(you)于電(dian)(dian)(dian)能(neng)表帶有斷電(dian)(dian)(dian)裝(zhuang)置，可以實現(xian)一些(xie)輔助功能(neng)，如負荷控制、過流保護(hu)等等。并(bing)(bing)且(qie)使(shi)用預付(fu)費(fei)電(dian)(dian)(dian)能(neng)表后，可以方便(bian)地實現(xian)增容。
預付費(fei)電(dian)(dian)(dian)(dian)表（一(yi)(yi)(yi)(yi)代）或簡(jian)稱經典款，電(dian)(dian)(dian)(dian)表上顯示(shi)剩余電(dian)(dian)(dian)(dian)量(liang)，總用(yong)(yong)電(dian)(dian)(dian)(dian)量(liang)等，直接插(cha)(cha)(cha)用(yong)(yong)戶(hu)卡(ka)(ka)(ka)使用(yong)(yong)。電(dian)(dian)(dian)(dian)表清(qing)零(ling)，需進線(xian)斷(duan)(duan)電(dian)(dian)(dian)(dian)30秒(miao)，通(tong)電(dian)(dian)(dian)(dian)后先(xian)插(cha)(cha)(cha)清(qing)零(ling)卡(ka)(ka)(ka)再插(cha)(cha)(cha)預置卡(ka)(ka)(ka)才能(neng)斷(duan)(duan)電(dian)(dian)(dian)(dian)。只收取電(dian)(dian)(dian)(dian)費(fei)，電(dian)(dian)(dian)(dian)費(fei)為零(ling)時(shi)自動斷(duan)(duan)電(dian)(dian)(dian)(dian)。每次充(chong)電(dian)(dian)(dian)(dian)之前，用(yong)(yong)戶(hu)需要(yao)先(xian)插(cha)(cha)(cha)一(yi)(yi)(yi)(yi)下電(dian)(dian)(dian)(dian)表，把(ba)電(dian)(dian)(dian)(dian)表里(li)的數據返回到卡(ka)(ka)(ka)里(li)才能(neng)充(chong)值，充(chong)值后再去插(cha)(cha)(cha)電(dian)(dian)(dian)(dian)表，否則數據容(rong)易報(bao)錯。預付費(fei)電(dian)(dian)(dian)(dian)表一(yi)(yi)(yi)(yi)表一(yi)(yi)(yi)(yi)卡(ka)(ka)(ka)，卡(ka)(ka)(ka)不(bu)用(yong)(yong)一(yi)(yi)(yi)(yi)直插(cha)(cha)(cha)著電(dian)(dian)(dian)(dian)表，充(chong)值后拔出IC卡(ka)(ka)(ka)保管好就可(ke)以。
預付費電表（二代），電表上顯示剩余金額，總用電量等。每臺電腦都有獨立的序列號防盜性更強，插用戶卡之前，每只表要先插設置卡，讓所有的電表認您的售點系統。電表清零無需斷電，減少用戶的操作麻煩，可收(shou)取電(dian)費(fei)(fei)，物(wu)業費(fei)(fei)，租費(fei)(fei)及其他費(fei)(fei)用，物(wu)業費(fei)(fei)房(fang)租費(fei)(fei)到(dao)期(qi)不斷(duan)電(dian)，電(dian)費(fei)(fei)為零(ling)時(shi)，如果此(ci)時(shi)物(wu)業費(fei)(fei)房(fang)租費(fei)(fei)也提前到(dao)期(qi)，充(chong)電(dian)系統會(hui)提示先(xian)補交房(fang)租費(fei)(fei)物(wu)業費(fei)(fei)，否則將電(dian)費(fei)(fei)將無法充(chong)值，方便房東(dong)或(huo)物(wu)業(ye)公(gong)司收取，房租費，物(wu)業(ye)費等費用(yong)。售電時用(yong)戶卡直接在系(xi)統里進行充值(zhi)，就可以插(cha)(cha)電表使(shi)用(yong)。預付費電表（二代）IC卡不用(yong)一直插(cha)(cha)著電表，充值(zhi)后拔(ba)出IC卡保管好就可以。
預付費電表（三代），電表上顯示剩余金額，總用電量，物業費，房租費等剩余天數及北京時間等。每臺電腦都有獨立的序列號防盜性更強。插用戶卡之前，每只表要先插設置卡，讓所有的電表認您的售點系統。電表清零無需斷電，減少用戶的操作麻煩，可收取電(dian)(dian)費(fei)(fei)(fei)(fei)，物業費(fei)(fei)(fei)(fei)，租(zu)費(fei)(fei)(fei)(fei)及其(qi)(qi)他費(fei)(fei)(fei)(fei)用。物業費(fei)(fei)(fei)(fei)，房租(zu)費(fei)(fei)(fei)(fei)，電(dian)(dian)費(fei)(fei)(fei)(fei)等，只要(yao)其(qi)(qi)中某一項費(fei)(fei)(fei)(fei)用到期，電(dian)(dian)表自動斷電(dian)(dian)。售(shou)電時用戶卡直接在系統里進行(xing)充值，就可以插(cha)電表(biao)使用。預付費電表(biao)（二代(dai)）IC卡不用一直插(cha)著(zhu)電表(biao)，充值后拔出(chu)IC卡保管好就可以。
