Product Details

product description

●summary

Digital measurement and control power instruments are a series of products designed for the power measurement and control needs of power systems, industrial and mining enterprises, and other industries. It can measure many commonly used power parameters with high precision, such as three-phase voltage, three-phase current, three-phase voltage current combination, three-phase active power, etc. It also has four switch input measurement functions (realizing "shaking signal") and 2-3 relay circuit output functions (realizing "remote control") with RS-485 digital interface, and uses standard MODBUS-RTU protocol to achieve "shaking measurement" function. The variable ratio communication parameters can be programmed and set through the instrument panel buttons, making it flexible and convenient to use.
