STS Standard Single Phase Anti-tamper Keypad Prepaid Energy Meter
Product introduction
STE18-A is an advanced single phase electricity metering device based on modern communication technology, computer technology and measurement technology to collect, analyze and manage electricity information data.The basic principle of this smart electricity meter is: relying on A/D converter or metering chip to carry out real-time collection of user current and voltage, through CPU analysis and processing, to realize forward and reverse, peak valley or four quadrant electric energy calculation, and further output electric quantity and other contents through communication, display and other ways.
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 users get electricity |
|
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, and data can be kept for more than 10 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 with 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.
