The characteristics of single-phase smart meters

Main features:
Alarm function: When the remaining battery capacity is less than the alarm when the remaining battery Electric energy meter often significant remind users to purchase electricity
Data protection: Data protection all-solid-state integrated circuit technology, power after more than 10 years of data retention
Power Tip: When the remaining battery power is equal to the alarm, trip off once, the user must insert the IC card, restore power supply, the user shall promptly

purchase at this time.
Auto power off: When the remaining battery electric meter is zero, the power meter automatically trip, uninterrupted power supply, the user shall promptly purchase at

this time.
Write-back function: power card to the user's accumulated power consumption, remaining capacity, zero is written back to the sale of electricity power system to

facilitate management department statistics management.
Users sampling function: electricity sales software provides data sampling electricity and on request of the user priority sampling sequence
Electricity query: insert the IC card in turn displays the total purchase quantity, purchase frequency, the last purchase of electricity, total electricity

consumption, the remaining power
Anti-theft features: a table and a card can not be copied, logical encryption. Effectively prevent technical stealing.
Overvoltage protection function: When the actual electrical load exceeds the set value, the meter automatically power off, insert the user card, restore power.
Low power consumption: using the latest design and advanced SMT production process.
