Overview: The three-phase power meter adopts AC sampling technology for calibration measurement, which can simultaneously measure and display three-phase active power or three-phase reactive power in the power grid. Programming and magnification can be set through panel buttons, making it cost-effective. It has the characteristics of easy installation, simple wiring, convenient maintenance, small engineering quantity, programmable input parameters on site, and can complete network communication with different PLCs and industrial control computers in the industry.
Measurement: three-phase active power, three-phase reactive power
■ Display: Three row digital tube (LED) display, STN blue screen, wide viewing angle, high-quality, high-definition LCD screen display
Communication: RS485 communication, MODBUS-RTU protocol
■ Input: Four channel switch input (4DI)
■ Output: Four channel switch output (4DO), four channel analog output
