IC卡預(yù)付費水表


  • 產(chǎn)品特點
  • 超長待機(jī)壽命:鋰電池供電,設(shè)計使用壽命≥10年;
  • 超低功耗:靜態(tài)功耗≤10uA,年均功耗≤120mA;
  • 低壓關(guān)閥:當(dāng)電流≤2.7v時,水表自動關(guān)閥;
  • 防磁攻擊:當(dāng)磁性物體靠近時,水表自動關(guān)閥;
  • *防護(hù)等級:防護(hù)等級達(dá)到并優(yōu)于IP68;
  • 保密性強(qiáng):邏輯加密,一表一卡,不可破解復(fù)制;
  • 斷電關(guān)閥:當(dāng)水表線路受到強(qiáng)力攻擊切斷線路時,水表由內(nèi)置電容瞬時釋放大量電流立刻關(guān)閥。
Product features
Ultra long standby life: Powered by lithium batteries, designed for a service life of ≥ 10 years;
Ultra low power consumption: static power consumption ≤ 10uA, annual power consumption ≤ 120mA;
Low pressure valve closing: When the current is ≤ 2.7v, the water meter automatically closes the valve;
Anti magnetic attack: When a magnetic object approaches, the water meter automatically closes the valve;
Maximum protection level: The protection level reaches and is superior to IP68;
Strong confidentiality: logical encryption, one table, one card, non cracked and non replicable;
Power off and valve closing: When the water meter circuit is cut off by a strong attack, the water meter will instantly release a large amount of current from the built-in capacitor and immediately close the valve.
