Product introduction
The product is an STS standard three phase prepaid electricity meter with a box which contains circuit breaker inside.It has integrated keypad to recharge by TOKENS and check information by short codes. Its prepayment function means user must pay first and then can use electricity,if no credits in the meter,electricity will be cut off.Stronpay vending software could be integrated to local mobile money payment platform via API, like M-PESA, Alipay, MTN, Airtel, etc.This energy meter can be both applied for residential and commercial place.It has low power consumption, high reliability, high precision and stable function, convenient to use and maintain.
Three phase watt-hour meter is applicable to commercial buildings and public infrastructure buildings to realize the measurement and statistics of electric consumption in different areas or different loads in buildings. Three phase watt-hour meter is suitable for the statistics and internal accounting of electric energy consumption of different production lines or loads in industrial buildings. |

Basic functions and characteristics
●High reliability:the accuracy remains unchanged for a long time, without wheel calibration, installation and transportation influence. ●Accuracy:wide range, wide power factor, start sensitive, etc. ●TOU tariff:utilities can set step price on request. ●Prepayment:after payment,then electricity is available for users. ●Anti-tamper:meter will automatically close the valve after detection of magnetic field and open cover event. ●Remote reading:by RF-LoRa to connect DCU for remote reading. ●Cost performance:high cost performance, can be reserved expansion function, seldom affected by the price rise of raw materials. ●Credit alarm:alarm value can be set by inputting corresponding TOKEN.When the remaining electric quantity is less than the alarm quantity, the electricity meter often shows the remaining electric quantity to remind the user to buy electricity. ●Data protection:data protection adopts all solid state integrated circuit technology, data can be kept for more than 5 years after power failure. ●Automatic power off:when the remaining quantity in the electricity meter is zero, the electricity meter will trip automatically and cut off the power supply. Users should purchase electricity in time. ●Electricity query:use keypad to input codes to display the total electricity purchase, the number of electricity purchase, the last electricity purchase, the cumulative electricity consumption, the remaining electricity. ●Overvoltage protection:When the actual load exceeds the set value, the meter will automatically cut off. |

How to recharge
●Via Stronpay vending software:users can directly go to local point of sales,pay for the electricity they want,then get TOKEN of the electricity meter,use keypad to input TOKEN and recharge successfully.
●By the third party platform or local mobile payment via API:considering some utilities are so far away from user’s home,and meanwhile since digital economy developed so fast,most local energy companies have their own vending platform,we can provide the API which is application program interface, coming to the agreement connecting the third party APP and our Stronpay vending software. |
