功能特點
1、采用邏輯加密IC卡，實現一表（一戶）一卡。
2、用戶新購電量與表內剩余電量可以累加，用戶一次最多可購999度電，累計剩余電量加新購電量＞999.9度時，用戶無法將用戶卡中的電量寫入電表，電表LED顯示“Err4”，待用掉部分電量后才可繼續寫電。
3、當電能表中剩余可用電小于20 kWh時，右上側的告警燈亮紅色，提醒用戶購電。當電能表中剩余可用電量為0kWh時，電能表自動斷開，中止供電，右上側的告警燈由亮紅色轉為紅色閃亮，直到插入有效電量的電能卡為止。
4、加電自檢功能,用戶將卡插入卡座，電能表讀卡完畢后，LED將顯示各種信息。
5、用電負荷連續超過功能定值時，自動斷電，通過插入IC卡，方可恢復供電。
6、當用戶使用不當或電表出現故障時，按鍵后可顯示出錯信息， 以提示用戶或供電部門的巡視。
7、防竊電功能：采用雙向電能計量集成電路及防竊電端蓋組合。
8、回寫功能：表內的累加用電量、剩余電量、超負荷次數以及常用信息回寫至IC卡，便于電力部門通過售電系統對其進行管理。
9、數據保護：數據保護采用全固態集成電路技術，無需使用電池，斷電后數據可保存10年以上。
10、一卡通設計：可實現水表、電表、燃氣表一卡管理。
Single-phaseIC Card Ammeter
Rated voltage: 220V
Demarcated current: 5（30）A 10（40）A (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 function：Adopt thecombination of two-way power metering integrate circuit and electricity larcenyprevention cover.
5. Write back function：Write backthe total consumption of electric quantity, remaining balance, over load times,ａnd the information to the IC Card for the convenience of management.
6. Dataprotection：Apply 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.
