DC metering is used in specific applications to measure, collect, and store real-time data for DC power systems. It is widely used in various industries such as solar systems, EV charging stations, battery energy storage systems
EM613001/EM613005 DC energy meters are designed for measuring and monitoring in DC systems. They are an ideal solution for measuring and monitoring in DC systems. The din rail DC energy meters can measure of important DC parameters: Voltage, current, power and energy etc. It also support bi-directional measurement with pulse output. All data in the meter are accessible via RS 485 using Modbus RTU. The meter has two versions working with AC or DC power supply. Input voltage range up to 1000V DC, and current inputs are flexible with DC shunt. The multi-tariff version has a RTC equipped inside, it can provides multi-tariff information and monthly records.

The Application of DC Energy Meter.
DC energy meters are used to measure the electrical energy consumed by a direct current (DC) load. They find applications in various industries such as renewable energy systems, telecommunications, data centers, electric vehicles, and battery storage systems.
In renewable energy systems, DC energy meters are used to monitor the power output of solar panels, wind turbines, and other renewable sources. In data centers and telecommunications, DC energy meters are used to measure the power consumption of servers and network equipment.
In electric vehicles, DC energy meters are used to measure the power consumed during charging and discharging of the vehicle's battery. They are also used to monitor the performance of the battery storage systems in various applications such as renewable energy systems, backup power systems, and off-grid power systems.
The Benefits/Advantages of DC Energy Meter.
DC energy meters offer several benefits and advantages, including:
Accurate measurement: DC energy meters provide accurate measurements of energy consumption, making it easier for users to monitor their energy usage and optimize their energy consumption.
Easy installation: DC energy meters are easy to install, making them an ideal solution for both residential and commercial applications.
Cost-effective: DC energy meters are generally cost-effective, and their accurate measurement of energy consumption can help users save money by reducing their energy usage.
Real-time monitoring: DC energy meters provide real-time monitoring of energy consumption, allowing users to track their energy usage and identify areas where they can reduce their energy consumption.
Data logging: DC energy meters can log energy consumption data, which can be used for analysis and reporting purposes.
Remote access: Many DC energy meters allow for remote access, enabling users to monitor their energy consumption from anywhere using a smartphone or computer.
Safety: DC energy meters are designed to be safe and reliable, ensuring that they do not pose a hazard to users or the environment.
Cautions of DC type Din Rail Meter:
1.About AC/DC & Application
(1) AC- Generally speaking alternating current usually means the input voltage , for example 220/230Vac for house appliance, 380Vac.
However DC for industrial field. In a word AC type energy meter is necessary when measuring in such condition.
(2) DC- Comparing with AC type meter, or AC whole current static energy meter, DC type Din Rail Meter was mainly used for direct current
measuring. It also means not for household and it;scarce.
(3) The application of DC din rail meter mainly exist where power storage for example power storage system, power generator, battery
system etc. It was also used for recharging such as EV charging pile.
2.About Function
(1) Measuring- current measuring achieved by shunt sampling which is cost-efficient and of good accuracy.
(2) Communication- RS485 Communication or RS485 & NB-IOT communication optional, which can also serve as DCU -sending data to the icloud.
(3) Tariff-4 tariffs with 8 slots.
3.Cautions
(1)Installation-Experienced electricians or professionals are required to install electricity meters and make sure that you have read this user guide.
In the process of installation, if the cover has obvious damage marks caused by severe impact or fall, please do not install or power up, and contact
with us immediately;Electricity meters can be installed and used directly if they pass the inspection before leaving the factory;The electricity meter
should be installed in the indoor or outdoor electricity meter box.The mounting base shall be fixed on a solid fire-resistant wall, and there shall be
no corrosive gas in the air;Electricity meters should be wired according to the wiring diagram on the terminal.Copper wire or copper wiring connector
are the best ways to access.
(2)Sealing- Plz fasten the sealing bolts or seals after installation in case of tamper events.
(3)If you have further questions while using plz contact us any time.
