Despite the mechanical meter’s ruggedness, which led to a market dominance even in modern times, the increasing demand for automatic meter reading (AMR) capability, as well as the requirement of less susceptibility against tampering attempts, drive the development of electronic meters with mechanisms for remote data acquisition and processing. The latter meters referenced are called “Smart Meters” and the purely electronic variants with no AMR functionality are called “Static Meters”.
Consequently, price aggressiveness becomes more important for static meters as compared to smart meters, especially with respect to cost competitiveness requirements, with two parameters – power consumption and cost effectiveness – driving the final component choices. This is a power and cost-optimized solution for static meters.
Renesas' Lab on the Cloud is an online environment where Renesas solutions, including popular evaluation boards, winning combinations and software, are hosted in a remote lab that customers access and test online.
The single-phase energy meter design is based on RL78/I1C and it is used for single-phase power and energy measurement.
