DTSY-121YF型三相电子式预付费电能表
详情

DTSY-121YF型预付费三相电子式电能表是一种由用户预先向供电部门缴纳电费,然后限量负荷电的计量仪表,采用美国芯片计量脉冲及量新加密型IC卡进行用户与管理系统之间的数据传递,确保数据安全可靠,一户一卡,具有防窃电功能;可广泛应用于工矿企业,居民小区物业管理及城乡电网改造。本产品名项性能指标符合IEC62052-11、IEC62053-21、GB/T17215.321-2008和GB/T18460.3-2001标准中对电子式三相预付费电能表的全部技术要求。
DTSY-121YF series three-phase electronic prepayment energy meter adopted high performance American special chip for prepayment meter. This meter has prepaid function, users should purchase electricity by IC card first then to use the power. This meter is the best way to solve payment-collect problem. It has many functions such as anti-tampering, load control, management of energy consumption and users' information, etc. The meter is used to measure 50Hz or 60Hz active energy consumption from three phase AC electricity net.The meter is widely used in office buildings,shopping malls,residences,airports and metro,etc.The meter complies with the technical requirements of standard IEC62052-11 and IEC62053-21.GB/T17215.321-2008,and GB/T18460.3-2001《Prepayment Energy Meter》.

有功电能表计量精度稳定,基本不受频率、温度、电压、高次谐波影响,出厂后无需调整,可延长检定周期;
采用加密卡进行数据双向传输,数据安全可靠;购电卡能回抄电表最新用电数据,便于控制电表的运行情况;
预购电量,先买,后用,用尽拉闸,不赊电;
剩余电量报警功能,报警值可设定,超限拉闸,插卡恢复供电;
限制负荷功能,超限拉闸,插卡或定时自动恢复供电;
丢卡处理功能,可随时补办用户购电卡,不会给供电双方带来经济损失;
八位液晶显示,电表剩余电量,液晶及时显示,电表运行状态代码;
具有双向计度功能,正、负两个方向有功功率以同一方向累计电能,起到防窃电作用;
对于S型电能表新加了RS485或红外通讯功能。(可选)

The meter is with stable accuracy, basically not affected by frequency, temperature, voltage, high-order harmonics, no need for adjustment after leave the factory, can  extend the period of calibration .
The meter use encryption cards for bidirectional data transmission, data security and reliability; IC card can copy back to the latest electricity data, easy to control the operation of the meter;
Prepaid power, buy electricity first, then can use, cut of power when electricity use out.
Remaining power alarm function, alarm value can be set, power off when electricity down to alarm quantity,insert IC card to recovery power supply.
Limit the load function, cut off power when overload.
Lost card processing functions, users may at any time re-make electricity card. No losses for both users and power supply department.
8-bit LCD display, meter remaining power, meter operating status.
With bidirectional metering function,measure positive and negative active power in the same direction,in order to anti-tampering.
For the meter with S type,may adding new RS485 or infrared communication function. (Optional)
