DR9 series three-phase multifunctional power recorder

3.5-inch 320 * 240 pixel TFT color LCD display screen, displaying in both Chinese and English the true effective value voltage, current, frequency, active power, reactive power, power factor, active energy value, reactive energy value and other parameter curves in a three-phase AC circuit. Real time recording of voltage, current, active power, reactive power, power factor, active energy value, reactive energy value, and various reports can be generated. The recorded parameter curves, historical data and power reports can be saved to a PC for data analysis through a USB flash drive or SD card. It provides RS485 communication interface and supports MODBUS-RTU protocol, which can be widely used in medium and low voltage distribution cabinets, industrial automation, intelligent switchgear, etc
