使用場(chǎng)合:可用在沒(méi)有諧波干擾的工頻電網(wǎng)中需測(cè)量電量參數(shù)的場(chǎng)合;不能用在有變頻器、軟啟動(dòng)器或可控硅調(diào)壓、逆變器(光伏項(xiàng)目用)等干擾大的場(chǎng)合。
一、概述
主要用于對(duì)電氣線路中的直流電壓、電流進(jìn)行實(shí)時(shí)測(cè)量與指示,具有測(cè)量精度高、穩(wěn)定性好、長(zhǎng)期工作免調(diào)校、可通過(guò)面板按鍵現(xiàn)場(chǎng)設(shè)置參數(shù)等特點(diǎn),是原指針式儀表或普通數(shù)字式儀表的理想換代產(chǎn)品。
采用SMT生產(chǎn)工藝,線路簡(jiǎn)潔、可靠性高;
交流采樣為方均根值 測(cè)量方式;
儀表量程可編程設(shè)置;
可具備越限報(bào)警輸出功能,報(bào)警上下限、切換差、輸出延遲時(shí)間及上電報(bào)警抑制功能可編程設(shè)置;
獨(dú)特的安裝方式,無(wú)須借助工具即可輕松完成安裝;
智能表的性能、普通表的價(jià)格。
