HB-SW系列(lie)單相(xiang)高精(jing)度(du)全自(zi)動(dong)交流穩(wen)壓器(qi)(qi)是由接觸(chu)自(zi)耦調壓器(qi)(qi)、伺服電(dian)(dian)動(dong)機、自(zi)動(dong)控(kong)制電(dian)(dian)路等組成。當電(dian)(dian)網(wang)電(dian)(dian)壓不穩(wen)或負載變(bian)化時自(zi)動(dong)采樣，控(kong)制電(dian)(dian)路發(fa)出信號驅動(dong)伺服電(dian)(dian)機，調整自(zi)耦調壓器(qi)(qi)碳刷的位置，使(shi)輸(shu)(shu)出電(dian)(dian)壓調整到額定(ding)(ding)值并達到穩(wen)定(ding)(ding)狀態。本儀器(qi)(qi)體積小、重量輕、輸(shu)(shu)出波形(xing)失(shi)真小、性能(neng)可靠、可長期運(yun)行等特點，設(she)有過壓保護功(gong)能(neng)，根(gen)據用(yong)戶需要，可設(she)欠壓、延時等保護功(gong)能(neng)。可廣泛用(yong)于任何(he)用(yong)電(dian)(dian)場所，是一種理想的穩(wen)壓電(dian)(dian)源。
