1.EM series DC energy meters are designed for measuring and monitoring in DC systems.
2.The din rail DC energy meters can measure of important DC parameters: Voltage, current, power and energy etc. It also
support bi-directional measurement. All data in the meter are accessible via RS485 using Modbus RTU/DTL645.
3.The meter working with DC power supply. Input voltage range up to 1000VDC, and current inputs are flexible with DC shunt.
4.The multi-tariff version has a RTC equipped inside, it can provides multi-tariff information and monthly records.
5.It can also be equipped with digital inputs for switch monitoring, relay outputs for remote control, and an over-range alarming
6.EM series dc meter is designed for scenarios such as DC panel, solar PV system, battery storage system, EV charging pile,
telecom base stations, transportation systems, power distribution systems, smart home and smart city.

Cautions of DC type Din Rail Meter:
(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.
(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
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.
