UPS的發(fā)展趨勢(shì)是怎樣的？ </p> <p> 發(fā)展UPS技術(shù)的主要目的是提高UPS對(duì)輸出端負(fù)載的動(dòng)態(tài)響應(yīng)越來(lái)越快又好。顯然，采用先進(jìn)的高頻技術(shù)，動(dòng)態(tài)響應(yīng)速度很快，效果比較好。 </p> <p> 傳統(tǒng)工頻機(jī)帶輸出隔離變壓器是否可以增加帶載能力和降低零地電壓？ </p> <p> 工頻機(jī)的輸出隔離變壓器嚴(yán)格講是它逆變部分不可或缺的組件，沒(méi)有全隔離效果，因?yàn)榕月窡o(wú)隔離，零線無(wú)隔離。 </p> <p> UPS上有防雷嗎？ </p> <p> UPS可以選配輸入C級(jí)防雷，它有兩種方式： </p> <p>
