The PD1351 installation type digital multifunctional power monitoring instrument is a power instrument that integrates measurement recording, large screen LCD display, and communication. It can measure the three-phase voltage, three-phase current, three-phase active power, three-phase reactive power, three-phase apparent power, three-phase power factor, and frequency of the power grid, and can also measure the total and phase separated reactive power. The RS485 communication interface supports the DL/T645-2007 communication protocol. The instrument has 2 switch inputs and 2 switch outputs, which can achieve local or remote switch signal monitoring and control output functions (i.e. "remote signaling" and "remote control" functions). Instruments are suitable for energy management systems, substation automation, distribution network automation, residential power monitoring, industrial automation, intelligent distribution panels and switchgear, including use in power plants, hydropower stations and other electrical management automation systems.
