1、Powerful Function: High-precise measurement, real-time monitoring of voltage, current and power of each channel when generating and consuming kilowatts. 2、Mobilephone APP Control: The app displays real-time power, current, voltage, power factor and frequency of channel for forward and reverse. 3、Power Statistics: APP program displays daily, monthly and yearly reverse and forward totals of channel individually. Power usage percentage display to avoids abnormal power usage. 4、Automation Function: You can set the power or current value in APP, only when the power or current exceeds the value, the device will starts to work. 5、Feature-rich Design: Automated setting of valve-values and push notifications, and the device is able to be calibrated by adjusting the percentage. 6、Easy Installation: 35mm rail mounting, no need to replace wires connection is safer, just put the wires in the clip and measure. 7、Note: ZigBee products need to be used with gateways.
