ROWATT DTSU666 Three-Phase Smart Meter
OVERVIEW
DTSU666 series three phases four wire electronic energy meter(din-rail) is designed based on power monitoring and energy metering demands for electric power systems, the communication industry, the construction industry, etc. as a new generation of intelligent instrument combining measurement and communication functions, mainly applied into the measurement and display for the electric parameters in the electric circuit including three voltage, three current, active power, reactive power, frequency, positive&negative energy, four-quadrant energy, etc. Adopting the standard DIN35mm din rail mounting and modular design, it is characterized with small volume, easy installation and easy networking Can be applied into Growell Hybrid inverter and AC coupled inverter.

Installation
-
The network cable is described as follows:
- LAN line 1-8 colors as below:
-
Cut the crystal head, find out PIN1 and PIN5, and connect the communication terminals according to the picture.
-
Connect the communication terminals as shown.
-
Connect the communication terminals to the 30-pin communication terminals of the inverter.
-
The standard RS485 cable length is 15m. If need a longer RS485 cable, please use an ethernet coupler to extend and make sure RS485 cable less than 100m(the recommended length is less than 25m).
-
MOD XH system application block diagram wiring is as follows.
Note
- Be careful the wire of input and output of L/N and the range of input voltage or current, if the data is outrange, it may destroy the meter.
- Be careful the input and output of meter line, if lines are wrong. system will work in a wrong way.
Note: If there is no communication (MOD-XH shows warning 401 or meter communication indicator is don’t display), please check the communication LAN line, baud rate, and address.
Display
From the displayed interface, the electrical parameter and energy data are all primary side data (that is, the multiplied by current and voltage ratios). The energy measuring value will be displayed seven bits, with the displaying range from 0.00kWh to 9999999Mwh.
Note: This meter and MOD-XH default communication address is 04, the baud rate is 9600, if the meter and MOD-XH communication is not on.you can confirm the communication address and baud rate is accurate, view and modify the path as follows
Button description: “SET” button represents “confirmation”, or “cursor shift”(when input digits), “ESC” button represents “exit (A) button represents “add”. The input code is (default 701).
