This product has the characteristics of high precision, high sensitivity, high reliability, wide load, low power consumption, small size, light weight, and easy installation and management. The circuit design is reasonable, all components used have been strictly screened, and there is a high degree of redundancy to ensure the long-term stable operation of the electricity meter, and the accuracy is not affected by frequency, temperature, voltage, and high-order harmonics. The starting current is small and there is no creep. This product has a bidirectional energy metering function, which can accurately measure the active power in both positive and negative directions, and accumulate energy in the same direction. It has the function of preventing various ways of electricity theft (such as reverse electricity theft, live wire short-circuit electricity theft, etc.).
