PD1081 Electric Power Distribution Monitor
General introduction:
PD1081 electric power distribution monitor integrates measurement, LCD display and communication, which can measure the grid current, voltage and frequency. one channel RS-485 communication interface can be configured, and MODBUS-RTU and DL/T645 dual communication protocol is supported. The monitor is applicable to all kinds of energy management system, substation automation, distribution network automation, residential power monitoring, industrial automation, intelligent switchboard and switch cabinet, as well as power plant, hydropower station and other automation system for electricity management. In addition, it follows the following standards: GB/T22264.2-2008, DL/T645, "multi-function energy meter communication protocol" and Modbus-RTU protocol.
