AMeter 390 High Accuracy Gateway Energy Meter (SF4 Series)

The aMeter 390 high-precision gateway energy meter (SF4 series) is a high-precision gateway energy meter suitable for settlement gateways of high-voltage level power grids such as regional and provincial power grids, power generation gateways for photovoltaic, wind power, hydropower, and electrified railways with frequent load changes. Details inquiry:

The aMeter 390 high-precision gateway energy meter (SF4 series) has complete measurement and management functions. Its measurement accuracy is superior to IEC62053-22 and IEC62053-23 standards, and the factory error can be controlled within ± 0.04%. It supports DLMS, IEC 1107, Modbus, DL/T645-2007, DL/T645-1997, and can be easily connected to various master station systems.
The aMeter 390 high-precision gateway energy meter (SF4 series) has strong anti-interference ability in harsh environments and long-term stable and reliable operation characteristics. The application of gateway metering points is becoming increasingly widespread.
