Mini Power Monitor Reference Design

Renesas' quick solution for accurately measuring the power consumption of electric appliances features the RL78/L13

Image of Renesas' Mini Power Monitor Reference DesignRenesas' quick solutions feature a reference design for a mini power monitor designed for users to accurately measure the power consumption of electronics. Using the RL78/L13 low power consumption LCD MCU, a high-precision current and voltage sampling circuit, a dedicated energy metering chip, and an LCD enable monitoring a variety of electrical parameters in appliances. To prevent fires, an alarm will go off when the ambient temperature is higher than +60°C. The device can be used for home appliances such as LED lamps, air conditioners, refrigerators, microwave ovens, and more. The mini power monitor can be used as a measuring instrument in teaching.
