The single-phase intelligent simulation energy meter is a new generation of intelligent high-tech energy metering product that complies with relevant energy meter standards such as Q/GDW1354-2013 "Functional Specifications for Intelligent Energy Meters", Q/GDW1364-2013 "Technical Specifications for Single-Phase Intelligent Energy Meters", Q/GDW1355-2013 "Type Specifications for Single-Phase Intelligent Energy Meters", Q/GDW1365-2013 "Technical Specifications for Security Authentication of Information Exchange for Intelligent Energy Meters", and DL/T645-2007 "Communication Protocol for Multifunctional Energy Meters".

• Meets the type and technical specifications of single-phase smart energy meters required by the power grid company.
• The meter supports multiple communication methods, with two RS485 interfaces, a carrier interface, an optional far-infrared interface, a 4G module interface, and a LoRa module interface.
• Data reading and remote control of the energy meter can be performed via RS485 or carrier/low-power wireless communication interfaces.
• Forward active energy, reverse active energy, and combined active energy
• Features time-of-use billing function, with support for setting special tariff time periods including the four tariff rates (ultra-peak, peak, flat, valley);
• Features a fault simulation function, enabling the simulation of on-site common faults in three major categories: display, data acquisition and metering, as well as the simulation of meter body faults and switching-on/off control faults. Wherein, meter body faults are further classified into dozens of types including meter body communication faults, sampling faults, display faults, LCD faults, clock faults and system crashes.
