PZ系列智能直流電能表是針對直流屏、太陽能供電、電信基站、充電樁等應(yīng)用場合而設(shè)計的,該系列儀表可測量直流系統(tǒng)中的電壓、電流、功率、正向與反向電能。既可用于本地顯示,又能與工控設(shè)備、計算機連接,組成測控系統(tǒng)。同時它具有多種外圍接口功能可供用戶選擇:帶有RS-485通訊接口,采用Modbus-RTU協(xié)議;可帶繼電器報警輸出、開關(guān)量輸入/輸出。根據(jù)不同要求,通過儀表面板按鍵,對變比、通訊進行設(shè)置與控制。
The PZ Series Intelligent DC power meter is designed for the application of DC screen, solar power supply, telecommunication base station, charging pile and so on. This series of instruments can measure voltage, current, power, forward and reverse power in the DC system. It can not only be used for local display, but also can be connected with industrial control equipment and computer to form a measurement and control system. At the same time, it has a variety of peripheral interface functions for users to choose: with RS-485 communication interface, the use of Modbus-RTU protocol, with relay alarm output, switch input / output. According to different requirements, variable ratio and communication are set and controlled through the instrument panel key.產(chǎn)品符合Q/GDW1825-2013《直流電能表技術(shù)規(guī)范》、GB/T29318-2012《電動汽車非車載充電電能計量》、Q/GDW364-2009《單相智能電能表技術(shù)規(guī)范》等標(biāo)準(zhǔn)的相關(guān)技術(shù)要求。
