194E-2S4 MCU design LED display AC and DC power distribution automation intelligent instruments

الوصف

BJ***4E series is to measure network parameters and the development of special electronic measuring instruments, parameter measurements are displayed on the monitor 5 groups, can simultaneously measure and manage over *0 network parameters. Supply line voltage, phase voltage, phase current, phase power factor, total current, active power, reactive power, apparent power, active power, reactive power and other network parameters; while providing phase current, total current, total power power, reactive power and apparent power demand value, all network parameters are a value, BJ***4E has a **5 communication interface, adjustable voltage, current transformer ratio and a variety of voltage mode so that it can adapt a variety of different voltage specifications of electricity occasions.

Features:

    1, real-time display
       Real-time display of three-phase power factor, phase active power, phase reactive power, three-phase voltage, phase current, active power, reactive power and so on.

    2, the basic power parameter acquisition
       The basic power parameters acquisition module: real-time acquisition of voltage and current signals and calculates the three-phase power factor, phase active power, reactive power three-phase, three-phase voltage rms, rms phase current, active power, reactive power Wait.

    3, the communication function
       Communication module has two supply the user with a choice of Freedom: 1, RS**5 / RS**2 2, USB utilize communication module with the host computer (PC or PLC) for wired or wireless communications, the use of background software can achieve preset parameters, real-time data collection grid and other functions.

    4, parameter presets
       Preset parameters can be done in two ways: 1, the use of simple keyboard provided by the meter; 2, use PC analysis software and instrument communication .

    5, communication protocol
       MODBUS RTU protocol, communication protocol can be customized such as: MODBUS ASCII, etc.
