Product introduction
STE18-S is an single phase prepaid electricity meter launched by Stron company,with STS standard compliant, split keypad type, automatically connection or disconnection. This single-phase electricity meter has the features of high accuracy, accurate measurement, low maintenance workload, high work efficiency, convenient for transportation and installation conditions, low power consumption, energy saving, good for reducing line loss, perfect anti-power theft function, strong overload ability, low failure rate.,long life quality and etc.
Single-phase prepaid watt-hour meter is suitable for commercial buildings and public infrastructure buildings to realize the measurement and statistics of electric energy consumption in different areas or different loads in buildings. It is also 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 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 |
