Product Description
Digital Monitoring Controller is designed for power system enterprises and industries for monitoring and controlling. They can measure most of common use electric parameters in high accuracy, such as three phase voltage, three phase current, three phase current and voltage combined, three phase active power, with the function of four loops switch value input measuring(remote surveillance) and 2/3 loops relay output(remote control) with RS485 interface, realize "remote measuring" function by MODBUS-RTU communication protocol. The transformation ratio can be programmable configured by the panel of the meter. The operation is easy and convenient.
