DDSY-121YF型单相电子式预付费电子表是我公司开发研制的具有电能计量、负荷控制和用户信息管理等多种功能的新一代产品,该表采用性能优良的美国预付费专用芯片,是当前改革用电体制、实理电能商品化、解决收费难及调节网负荷状态的理想产品。该产品可安装在室内或室外电表箱内,适应于环境温度为-25℃~+60℃,相对湿度不大于85%条件下使用。该产品各项性能指标符合IEC62052-11和IEC62053-21国际标准和GB/T18460.3-2001标准。GB/T18460.3-2001《预付费电度表》标准的全部技术要求。
DDSY-121YF series single-phase electronic prepayment energy meter is developed on the base of excellent single-phase electronic energy meter. It is a new type of IC card pre-paid meter, which has the functions like power measurement, load control and customer information management. This meter adopted high performance American special chip. It is an ideal product for reforming electric system, commercialize the electrical energy, solve the electric charge collection problem and adjusting load status in the electric network. The meter complies with the technical requirements of standard IEC62052-11 and IEC62053-21,GB/T18460. 3-2001,and GB/T18460. 3-2001《 Prepayment Energy Meter》.This meter can installed in indoor or outdoor within the meter box, operating in the ambient temperature -25°C~+60°C relative humidity not exceeding 85%.


金卡工程国际标准IC卡硬件加密,供电部门以出售用电卡(IC卡)的方式销售电量预收电费;
完全数字化计量、电量显示、预付费控制、读卡,智能防窃电等融为一体,具有极高的可靠性;
过负载保护: 负载超过设定最大电流20-30%连续10-15秒,切断供电回路;用电IC卡经软硬件多重加密,完全确保数据的安全、正确、可靠。经过特殊设计,用电IC卡上记录了用户插卡时电表的剩余电量和累计电量以及是否有窃电行为的信息;
完善的卡口保护电路具有防各种恶意攻击能力;
交替显示剩余电量、累计电量(当前功能)可选,显示位数为8位(两位小数位);
电量用完时断电报警,插入用电卡后继续透支使用,但液晶闪烁显示剩余电量,以提示用户需输入新的购电量;
所欠电量达到一定值(出公司前可设定,一般为-10kW.h)自动断电,输入新的购电量(扣除已透支的电量)后恢复供电;
磁保持继电器的应用,一方面提高了断电动作的可靠性,降低了断电动作后的功耗,同时也克服了继电器大电流长时间工作时触点沾连的毛病;
停电时,自动保存数据,来电自动恢复;
通用微机+专用IC卡读写器+收费管理软件构成售电管理系统;
对记录的信息进行对比分析,管理系统可以列出怀疑有窃电行为的用户,以便重点检查,减少防、查窃电行为的工作量;
对于S型电能表新加了RS485/红外通讯功能(可选)。
