STS Standard Keypad Type Prepaid IC Card Digital Single Phase Energy With RFID Card Reader
This single phase prepayment meter also called quantitative meter, IC card prepaid meter, in addition the ordinary energy meter measurement functions, especially the user need to buy electricity first, use second, after run out of power if the user does not continue to buy electricity.the meter will automatically cut off, this meter is best way to solve payment collection problem, it also has function of anti-tampering, over load protection, management of energy consumption and user information. This type of meter is widely used in office building, shopping mall, residential, and public facility etc.
Main Features
1. One meter has one card, fake card is not available. Repeatable top-up, Effectively reduce waste.
2. LCD 6+2 digits display, maximum 999999.99 kWh.
3.Automatic power off when overload, also can prevent the error overload when the load restart.
4. Once the prepaid meter available energy is reached zero, meter relay will automatically cut the power off, unless the station has set overdraw limit ( Credit ).
5. The meter can set alarming kWh quantity, indicated by LED flash and secondary notice user the energy is Low, it’s in order to remind user to recharge power on time, Avoid unnecessary loss.
6. The forward and opposite direction active power can be measured.
7. data can be preserved for more than 10 years without power supply.
