Single-phase fee control intelligent energy meter (wired) (remote carrier) is an intelligent energy metering product developed and produced by our company. It is suitable for the measurement of single-phase AC active energy with a rated voltage of 220V and a frequency of 50Hz. It has an independent modulated infrared optical port and a RS485 communication port, and is equipped with a carrier communication module standard interface. Multiple carrier communication modules can be selected. Through carrier communication or RS485 communication, it can support remote fee control function. The meter has the advantages of high reliability, high precision and long life. It adapts to a wide voltage range, and the whole machine does not need to be adjusted after leaving the factory. It can be widely used in single-phase AC metering occasions in cities, rural areas or factories and enterprises.

1. Designed and manufactured using advanced ASIC, SMT, hot air reflow and wave soldering processes, the product quality is reliable.

2. The electric energy metering unit, data processing unit and communication interface unit use three sets of isolated power supplies respectively. All output signals are photoelectrically isolated to improve electromagnetic compatibility performance. At the same time, it also ensures that the metering unit works independently and stably without being affected by the communication interface.

3. Wide voltage range design, can work normally from 154V to 265V, and the meter will not be damaged at 418V, which improves the adaptability of the meter to the working environment.

4. The microprocessor adopts a built-in watchdog design to ensure the reliable and normal operation of the CPU, and the metering data adopts triple backup. Under severe interference, the data is guaranteed to be safe.

5. Fully sealed dustproof and waterproof design, the case material has excellent flame retardant, corrosion resistance and aging resistance.

6. Use a hardware clock circuit with built-in temperature compensation function. The temperature compensation function is also activated when the battery is powered during a power outage to ensure accurate clock accuracy.

7. It has a standard interface for carrier communication module, and can be equipped with carrier modules from different manufacturers to improve product versatility.

8. Main functions: metering function, fee control function, measurement and monitoring, event recording, rate and electricity price plan, display function, alarm function, freeze function, timing function, pulse output.
