Project Description
I. General Introduction
DSS1598 Smart Two Phase Three Wire Meter is R&D by our own, apply to measure the nominal voltage(127V) two-phase meter’s AC active power. With far-infrared communication port, there are high reliability, high precision and long life feature of the meter. This meter can be widely used in two-phase (AC) in city, village and factory. This meter uses high accurate measurement chip of the three-phase to realize the metering accuracy of the two-phase AC active power. MCU read the impulse number to calculate the energy, and save to the nonvolatile storage. It can read the meter through far-infrared. The built-in nonvolatile storage can make sure the data can save at least 10 years after the system out of electricity.
II. Technical Specification
