FoxESS Three-phase Meter

Chint DTSU666 meters with backlit display are advanced multifunction devices designed for bidirectional, four-quadrant electricity metering in single- and three-phase installations.
In addition to bidirectional energy flow (export and import), the Chint DTSU666 meters also allow you to record and read many other network parameters, including capacitive and inductive reactive energy in the directions of consumption (import) and input to the grid (export). The meter has an RS-485 interface, so you can easily read out the measured values using the Modbus-RTU protocol. In addition, it has a configurable pulse output for active or reactive energy.
The device measures and transmits information on parameters such as: voltage (V), frequency (Hz), current (A), energy in the four-quadrant, (kWh / kVArh) imported into the network (export), downloaded (import) and total.
