1Application S3-WD-3-555A4B power transmitter
S3Series power transmitterIt is a technology developed by Ningbo Dongqi that can measure the measured AC current and voltage、Electricity signalAn instrument that converts direct current or voltage into a linear proportional output. Equipped with corresponding indicator instruments or devices, it is possible to achieve current Measurement and control of voltage.Suitable for on-site monitoring and display of power grids and automation control systems, as well as remote control and telemetry of remote control devices for automated scheduling. Its function is to convert electrical parameters such as current, voltage, power, frequency, power factor, and electrical energy in the power grid intoCPUControl direct communication samplingA/DOutput standard current, voltage, or switch signals after analog-to-digital conversion, and communicate with remote data terminalsRTUto be connected. Instrument'sRS-232orRS-485In the interface, data exchange can be directly carried out with the control center to achieve automated management. In addition, this series of instruments also has intelligent functions for non electric measurement, transmission, and alarm input and output, such as pressure, temperature, and flow.
At present, this series of instruments has been widely used in industries such as water conservancy, environmental protection, power, metallurgy, and railways.
