固緯PSW160-21.6直流電源  固緯PSW160-21.6直流電源  

PSW-系列是(shi)一款單(dan)路輸出(chu)、多(duo)(duo)量程(cheng)可(ke)編程(cheng)開關(guan)直流(liu)電(dian)(dian)源，zui大功率(lv)1080W。該系列涵(han)蓋15種(zhong)(zhong)機型，提供30V、80V、160V、250V和(he)(he)800V的(de)額定電(dian)(dian)壓和(he)(he)360W、720W和(he)(he)1080W的(de)zui大輸出(chu)功率(lv)。多(duo)(duo)量程(cheng)操作(zuo)可(ke)以(yi)靈(ling)(ling)活(huo)有效(xiao)的(de)設置電(dian)(dian)壓和(he)(he)電(dian)(dian)流(liu)。用(yong)戶(hu)zui多(duo)(duo)能串行(xing)連接(jie)2臺或(huo)并行(xing)連接(jie)3臺PSW電(dian)(dian)源，這種(zhong)(zhong)提供更高輸出(chu)電(dian)(dian)壓或(huo)電(dian)(dian)流(liu)的(de)連接(jie)能力極大的(de)擴展了(le)它的(de)應用(yong)范圍。靈(ling)(ling)活(huo)的(de)多(duo)(duo)量程(cheng)操作(zuo)和(he)(he)串/并聯連接(jie)，您(nin)無(wu)需(xu)再(zai)花(hua)費資(zi)金購買多(duo)(duo)種(zhong)(zhong)電(dian)(dian)源產品(pin)，PSW-系列*可(ke)以(yi)滿足不(bu)同(tong)層次的(de)電(dian)(dian)源需(xu)求(qiu)。

PSW-系(xi)列的(de)C.V/C.C優先(xian)選擇模(mo)(mo)式(shi)(shi)能夠很好的(de)保(bao)護待(dai)測(ce)物。當輸出(chu)開啟(qi)時(shi)，傳統電(dian)(dian)源(yuan)(yuan)通常處于C.V模(mo)(mo)式(shi)(shi)，這會(hui)瞬間給電(dian)(dian)容(rong)性(xing)負載(zai)或強電(dian)(dian)流(liu)(liu)(liu)負載(zai)帶來一個較大(da)的(de)浪(lang)涌電(dian)(dian)流(liu)(liu)(liu)。以LED的(de)I-V曲線(xian)驗證(zheng)為例，使(shi)用傳統電(dian)(dian)源(yuan)(yuan)就難以完成測(ce)量工作(zuo)。C.V模(mo)(mo)式(shi)(shi)下(xia)連接LED與電(dian)(dian)源(yuan)(yuan)，打開輸出(chu)，當電(dian)(dian)壓(ya)超過(guo)LED正(zheng)向(xiang)電(dian)(dian)壓(ya)時(shi)，電(dian)(dian)流(liu)(liu)(liu)突然增大(da)并超過(guo)預設限流(liu)(liu)(liu)值。由(you)于偵測(ce)到浪(lang)涌電(dian)(dian)流(liu)(liu)(liu)，電(dian)(dian)源(yuan)(yuan)由(you)C.V模(mo)(mo)式(shi)(shi)轉換為C.C模(mo)(mo)式(shi)(shi)。雖然模(mo)(mo)式(shi)(shi)轉換后電(dian)(dian)流(liu)(liu)(liu)逐漸穩定，但C.V和C.C相(xiang)交(jiao)處的(de)尖峰(feng)電(dian)(dian)流(liu)(liu)(liu)可能會(hui)造成待(dai)測(ce)物損(sun)壞。然而(er)，PSW-系(xi)列在輸出(chu)開啟(qi)瞬間，能優先(xian)運行在C.C模(mo)(mo)式(shi)(shi)，避免(mian)突發的(de)尖峰(feng)電(dian)(dian)流(liu)(liu)(liu)，保(bao)護器件免(mian)遭浪(lang)涌電(dian)(dian)流(liu)(liu)(liu)損(sun)壞。

PSW-系列設(she)計(ji)了可調斜率功能，用戶可以(yi)設(she)置輸出電(dian)(dian)(dian)(dian)(dian)壓或(huo)輸出電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的上(shang)升(sheng)時(shi)間(jian)(jian)(由低電(dian)(dian)(dian)(dian)(dian)平(ping)變(bian)為(wei)高(gao)電(dian)(dian)(dian)(dian)(dian)平(ping))和下降(jiang)時(shi)間(jian)(jian)(由高(gao)電(dian)(dian)(dian)(dian)(dian)平(ping)變(bian)為(wei)低電(dian)(dian)(dian)(dian)(dian)平(ping))。當電(dian)(dian)(dian)(dian)(dian)壓或(huo)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)準位變(bian)化(hua)時(shi)，可調斜率有利于待測(ce)物的特性(xing)驗證(zheng)。通常情(qing)況下，生產測(ce)試照(zhao)明裝置和大型電(dian)(dian)(dian)(dian)(dian)容時(shi)會在輸出打開瞬(shun)間(jian)(jian)引發浪(lang)涌電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)，這(zhe)嚴重縮短了DUT壽命。為(wei)了避免浪(lang)涌電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)破壞(huai)強電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)器件，在開關(guan)瞬(shun)間(jian)(jian)光滑和緩慢的電(dian)(dian)(dian)(dian)(dian)壓傳輸可以(yi)顯著(zhu)減少(shao)浪(lang)涌電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)，保護(hu)器件免遭(zao)大電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)損壞(huai)。

PSW-系(xi)列提供OVP和(he)OCP保護(hu)，保護(hu)電平默認為額定輸(shu)出電壓(ya)/電流的110%。一(yi)旦超(chao)過預(yu)設值(zhi)，輸出(chu)立刻(ke)關閉(bi)。PSW-系列標配USB Host/Device、LAN接口和(he)GPIB-USB及RS232-USB選配接口，所有接口(kou)均支持LabView驅動和數據記錄(lu)PC軟件。后面板的模擬控(kong)制(zhi)/監控(kong)接口，可以外部控(kong)制電源(yuan)開/關和外(wai)部監控輸(shu)出電(dian)壓和電(dian)流(liu)。
