产品详情


参数


额定电压:220V

标定电流:5(30)A   10(40)A   (15)60A   (20)80A

参比频率:50Hz

精    度:1.0 级   2.0 级

电表常数:3200 ~ 800imp/kWh

外型尺寸:168mm×110mm×62mm

IC卡形式:接触式卡


功能特点


1、采用逻辑加密IC卡,实现一表(一户)一卡。

2、用户新购电量与表内剩余电量可以累加,用户一次最多可购999度电,累计剩余电量加新购电量>999.9度时,用户无法将用户卡中的电量写入电表,电表LED显示“Err4”,待用掉部分电量后才可继续写电。

3、当电能表中剩余可用电小于20 kWh时,右上侧的告警灯亮红色,提醒用户购电。当电能表中剩余可用电量为0kWh时,电能表自动断开,中止供电,右上侧的告警灯由亮红色转为红色闪亮,直到插入有效电量的电能卡为止。

4、加电自检功能,用户将卡插入卡座,电能表读卡完毕后,LED将显示各种信息。

5、用电负荷连续超过功能定值时,自动断电,通过插入IC卡,方可恢复供电。

6、当用户使用不当或电表出现故障时,按键后可显示出错信息, 以提示用户或供电部门的巡视。

7、防窃电功能:采用双向电能计量集成电路及防窃电端盖组合。

8、回写功能:表内的累加用电量、剩余电量、超负荷次数以及常用信息回写至IC卡,便于电力部门通过售电系统对其进行管理。

9、数据保护:数据保护采用全固态集成电路技术,无需使用电池,断电后数据可保存10年以上。

10、一卡通设计:可实现水表、电表、燃气表一卡管理。


Single-phaseIC Card Ammeter


Rated voltage: 220V

Demarcated current: 530A   1040A   (15)60A   (20)80A

Frequency: 50Hz

Precision: Grade 1.0,Grade 2.0

Ammeter constant: 3200~ 800imp/kWh

Type of IC Card:   Contact Card.


Features:


1. Power metering: record and display total consumptionpower, remaining balance.

2. Prepayment function

a) Adopt cryptographic IC card. One meteronecard,no interchangeable.

b) The user’s newly purchased electricityquantity and remaining balance in meter can be accumulated.

c) When the remaining balance is less than 20kWh, the warning light on the up-right is on red to remind user to purchaseelectricity. When the remaining electricity is 0 kWh, the electric energy metershall cut automatically and the power is cut off, the warning light on theup-right changes from red to on red to blinking red until insert (sweep) ICcard with purchasing electricity quantity.

3 Monitoring function

a) Power-on self testing function, the userinsert (sweep) IC card, and the LED shall show the information after the cardis read by the ammeter.

b) The power is automatically cut off whenload continuously surpass the functional rated value, and the power can berecovered after inserting (sweeping) IC card.

4. Electricity larceny prevention functionAdopt thecombination of two-way power metering integrate circuit and electricity larcenyprevention cover.

5. Write back functionWrite backthe total consumption of electric quantity, remaining balance, over load times,and the information to the IC Card for the convenience of management.

6. DataprotectionApply overall solid integrate circuittechnology for data protection, so no battery is needed, and data can be remain kept for 10 years after theelectricity is cut off.

7. One-card design:It reaches theone-card management for eight kinds of meters such as: water meter, ammeter,gas meter, heat meter, etc., and the maximum quantity for each kind of metercan reach 7.
