Three phase digital voltmeterIt is a new generation programmable intelligent instrument that uses large-scale integrated circuits and high brightness long-life LED displays. It applies digital sampling technology to measure, display, and control the phase voltage and line voltage in three-phase electrical circuits in real time, and transmits the measured voltage data remotely through RS485 interface or analog transmission output interface.
　　Three phase digital voltmetercharacteristic:
★ Three screen five digit LED digital display.
★ Can directly collect three-phase AC voltage
★ It has optional functions of analog output, communication output, and cumulative power pulse output.
★ It has upper and lower limit alarm function, with LED alarm light indication.
★ Supports RS485 and RS232 serial interfaces, using standard MODBUS RTU communication protocol.
　　Difference from traditional pointer voltmeter:
Has strong anti-interference ability, reliability, stability, and high cost-effectiveness; The product is easy to operate and has complete functions.
Application scenarios:
Widely used in industries such as energy, machinery, chemical, and light industry.
