TIDM-TWOPHASEMETER-I2040 Low-Cost Single/Dual-Phase Isolated Electricity Measurement Reference Design | TI.com

TIDM-TWOPHASEMETER-I2040: The design implements a low-cost single- or dual-phase electricity measurement solution. The design separates a small metrology MCU from the host MCU, providing both protection from the AC mains and also isolation of the energy measurement function from corruption by other software. The small, low-cost metrology MCU achieves IEC/ANSI Class 1 accuracy and calculates active and reactive power and energy. This design is implemented using Current Transformer sensors for single and dual-phase measurement. It can also be easily modified for single-phase measurement with shunt resistor sensors.

Low-Cost Two-Phase Electric Meter

TIDM-TWOPHASEMETER-I2040: The design implements a low-cost two-phase electric meter system. This two-chip solution has a metrology processor for calculating metrology parameters and an additional host MCU that has the capability to drive the on-board LCD, add-on communication modules, and USB devices. Isolated communication between the metrology and host MCU is supported by on-board isolators.
