3.Working principle

DTS6111 three-phase four wire、 The working principle of DSS6111 three-phase three wire type three-phase static energy meter is shown in Figure 1.

This electric energy meter adopts a three-phase power supply mode and can work normally under any single-phase power supply situation.

When the electric energy meter is working, the voltage and current are sampled separately by the sampling circuit and sent to the large-scale dedicated integrated circuit for buffering and amplification. Then, they are converted into digital signals by a 16 bit A/D converter, processed by a digital multiplier, and sent to the CPU for processing. Finally, the CPU sends the processed data to the display section, step counter, and other output units as needed.
