● RS485 communication: used for parameter setting, data reading; DLT645 protocol/Modbus Protocol

● DC metering: using shunt sampling, high measurement accuracy; can measure DC power, current, voltage,

● Alarm function: Over-current alarm: When the current exceeds the CT1 value set by the meter, an alarm event occurs, and the alarm light on the electrical surface panel lights up (yellow light),

At the same time, the value of the corresponding alarm status register will change, and the user can read this register through communication to determine whether an over-current alarm has occurred.

● Display: LCD with backlight ,Support Various parameters display,energy data and Instantaneous parameters

● Firmware upgrade: RS485 local upgrade

The installation of the energy meter requires an experienced electrician or professional and

confirms that this user guide has been read;

During the installation process, if the casing is obviously damaged due to severe impact or

falling, please do not install, power on, and contact us in time;

The electric energy meter has passed the inspection before leaving the factory and is sealed

with lead. It can be installed directly.

The energy meter should be installed in an indoor or outdoor meter box. The mounting

base should be fixed on a solid refractory wall with no corrosive gas in the air;

The energy meter should be wired according to the wiring diagram on the terminal box,

preferably with copper wire or copper terminal.
