With the power statistics function, you can view daily, monthly, and year electricity by application and keep track of the power consumption at all time The application displays real-time power, current, Voltages, power factor, frequency, and electricity statistics for each channel in forward and reverse directions With the automation function, you can set the power or current value in the application. When the power or current exceeds the set value, the device will initiate to work. With a calibration function, the device can be calibrating by adjusting the percentage By adopting a WiFi connection and a high precise measurement, real-time viewing of Voltages, current, and power of each channel when generating and consuming kilowatts by application to realize intelligent management 35mm rails mounting, not need to replace wire connection, safe to use, just put wire in clip and measure, Manufacturer: JDNH
