SDM820 series products are composed of two types of single-function electrical measuring instruments and multi-functional electrical measuring instruments. This series of instruments can measure electric parameters such as current, voltage, power, power factor, and electric energy. It also has a harmonic measurement function, directly through the LCD screen. Display measurement results; It also has a variety of extended functions: RS485 communication, switch input, switch output, electric energy pulse output and multiple analog output; users can freely choose basic functions and extended functions, and can set magnification and modify data on site Cycle display time.
This series of meters can directly replace related auxiliary units such as power transmitters and measurement indicating meters. Through the selection of functions and expansion modules, it can achieve digital communication, transmission and four remote functions; it has been widely used in various switch cabinets, Power distribution (metering) boxes, AC and DC screens and communications and other power equipment.
