Electronic single-phase prepayment meter Main functions and features

1, the standard IC card hardware encryption advance fee, the electricity sector in order to sell electricity purchase card (IC card) way to sell electricity electricity in advance, users buy after the first use.
2, set completely digital metering, power display, prepaid control, card readers, smart anti-theft and other functions integrated, with high reliability.
3, over-load protection. Load exceeds the set maximum current 20-30% continuous period of time, cut off the power supply circuit. Automatic delay time meter will automatically switch on.
4, power IC card via multiple encryption hardware and software, fully ensure data security,  air circuit breaker . Specially designed,
Electricity users are recorded on the IC card when the card's remaining power meter and cumulative power and whether there stealing behavior.
5, perfect bayonet protection circuit, which can effectively prevent various malicious attacks on the behavior of the bayonet.
6 shows the remaining power, the digit is five.
7, the remaining battery charge reaches the pre-alarm, LED flashing display remaining power to prompt the user must enter a new share power.
8, when the remaining Electric energy meter meter is zero, the power meter automatically trip, uninterrupted power supply, this time, the user must purchase card holders to purchase electricity sales sector (electricity sector can have overdraft power settings, insert the card after the purchase of electricity users You can use a certain threshold energy), with the purchase of electricity with an effective

Electric card is inserted table only after the normal power supply.
9, owed ​​auto power consumption reaches a certain value, enter the new purchase of electricity (net of overdraft charge) automatically after power is restored.
10, magnetic latching relay applications, while improving operational reliability of power outages, reducing the power consumption after operation, but also to overcome the large  Voltage stabilizer  long hours relay contacts adhesions glass wool
11, power failure, automatically save data, calls automatically restore the data.
12, computer and dedicated IC card reader + fees management software constitute the sale of electricity management system.
13, on the comparative analysis of the recorded information, the management system can list users suspected of stealing behavior in order to focus on examination, to reduce defense, check stealing behavior workload. Electronic single-phase prepayment meter Main functions and features
