The electricity meter is a instrument used for electric energy metering and billing. As technology rapidly increases and the information age expands, the market demand for the function of energy metershas increased, from a single metering function to communication,tariff, event alarm, load curve, load control, anti-tamper, prepayment, etc. The prepaid meter in the mode of paying first and then using electricity effectively solves the problem of charging difficulty, and has been widely used in the market.
Over time, the function of prepaid meters has become increasingly abundant, and it has developed into Smart prepaid meters. Yongtailong’s D124065 STS standard prepaid meter is very popular in the African market.
- Technical Parameters
options like RS485 ,Wifine, G3 PLC and GPRS (support 4G communication, with fall back capability to 2G and 3G.) communication, protocol dlms/cosem（IEC 62056）
Support load ground connection, bypass detection, open cover detection, influence of external magnetic field, abnormal voltage record, live&neutral wire metering.
Divide into weekday timetable and weekend timetable, with 8 time period and 8 tariffs. Every timetable has a backup table for remote updating of backup timetable and configure the switching time. Meter will automatically switch the tariff table at the switching time.
Open cover, magnetic field, load ground connection, reserve current, over-voltage, low-voltage, low-frequency, overload, power-fail, low remaining power, and token record.
Meter has 3 operation modes: STS token mode, currency prepaid mode and post-paid (traditional) mode, which can be switched.
And the currency mode can be divided into tariff mode and step price mode. Modes can be configured through communication.
1. Enter the charging code via the keypad on the electrical surface board
2. Charging via communication
3. The prepaid meter can be equipped with indoor displays, and recharge via IHD;
The three recharge methods have high fault tolerance.
With the development of intelligence and IoT, prepaid meters application scenarios are More and more wide. Not only using to solve the problem of charging for residential users, but also for rental houses, storefront rooms, shopping malls, school dormitories, factory dormitories, etc. Prepaid meter can be easily managed with the prepaid system platform, the load control function is adopted to ensure the safety of power consumption.
