This device measures and displays various measurement elements of the power system, allowing remote monitoring of the measured data via RS-485 communication, and it can store data. By inputting the PT ratio and CT ratio, it measures and displays the voltage, current, active power, reactive power, apparent power, power factor, frequency, active energy, and reactive energy for each of the total 12 channels by phase. It also displays the average, maximum, and minimum voltage, current, power, and power factor over time. Features: - Supports three-phase input with a total of 12 channels and 36 current inputs. - Channel changes and displays can be made via button input, making it convenient to check measurement information by channel. - Remote power monitoring is possible using RS-485 communication (MODBUS-RTU). - Allows confirmation and storage of measured data by connecting via USB.
