PSW-系(xi)列是一(yi)款單路輸(shu)出、多量(liang)程(cheng)可(ke)編(bian)程(cheng)開關直(zhi)流(liu)(liu)電(dian)(dian)源，zui大(da)功率1080W。該(gai)系(xi)列涵蓋15種機型，提(ti)供30V、80V、160V、250V和(he)(he)800V的額定電(dian)(dian)壓(ya)和(he)(he)360W、720W和(he)(he)1080W的zui大(da)輸(shu)出功率。多量(liang)程(cheng)操作可(ke)以靈活有效(xiao)的設置電(dian)(dian)壓(ya)和(he)(he)電(dian)(dian)流(liu)(liu)。用(yong)戶zui多能串行(xing)(xing)連接2臺或并行(xing)(xing)連接3臺PSW電(dian)(dian)源，這(zhe)種提(ti)供更高輸(shu)出電(dian)(dian)壓(ya)或電(dian)(dian)流(liu)(liu)的連接能力極(ji)大(da)的擴展了它的應用(yong)范圍。靈活的多量(liang)程(cheng)操作和(he)(he)串/并聯(lian)連接，您無需再花費資(zi)金(jin)購買多種電(dian)(dian)源產品，PSW-系(xi)列*可(ke)以滿足不同層次的電(dian)(dian)源需求(qiu)。

PSW-系列(lie)的(de)(de)C.V/C.C優先(xian)選擇模(mo)(mo)(mo)式(shi)能(neng)夠很好的(de)(de)保護待(dai)測物。當(dang)輸(shu)出開(kai)啟時，傳統(tong)電(dian)(dian)(dian)(dian)(dian)源通常(chang)處于C.V模(mo)(mo)(mo)式(shi)，這會(hui)瞬(shun)間(jian)給電(dian)(dian)(dian)(dian)(dian)容性(xing)負載或強電(dian)(dian)(dian)(dian)(dian)流(liu)負載帶來一個較大的(de)(de)浪涌(yong)電(dian)(dian)(dian)(dian)(dian)流(liu)。以LED的(de)(de)I-V曲線驗證為(wei)例，使用(yong)傳統(tong)電(dian)(dian)(dian)(dian)(dian)源就難以完成測量工作。C.V模(mo)(mo)(mo)式(shi)下連接LED與電(dian)(dian)(dian)(dian)(dian)源，打開(kai)輸(shu)出，當(dang)電(dian)(dian)(dian)(dian)(dian)壓超過(guo)LED正向電(dian)(dian)(dian)(dian)(dian)壓時，電(dian)(dian)(dian)(dian)(dian)流(liu)突(tu)然增大并(bing)超過(guo)預設限流(liu)值(zhi)。由(you)于偵測到浪涌(yong)電(dian)(dian)(dian)(dian)(dian)流(liu)，電(dian)(dian)(dian)(dian)(dian)源由(you)C.V模(mo)(mo)(mo)式(shi)轉換為(wei)C.C模(mo)(mo)(mo)式(shi)。雖然模(mo)(mo)(mo)式(shi)轉換后電(dian)(dian)(dian)(dian)(dian)流(liu)逐漸穩定，但C.V和C.C相交(jiao)處的(de)(de)尖(jian)峰電(dian)(dian)(dian)(dian)(dian)流(liu)可能(neng)會(hui)造成待(dai)測物損壞。然而，PSW-系列(lie)在(zai)輸(shu)出開(kai)啟瞬(shun)間(jian)，能(neng)優先(xian)運行在(zai)C.C模(mo)(mo)(mo)式(shi)，避免突(tu)發的(de)(de)尖(jian)峰電(dian)(dian)(dian)(dian)(dian)流(liu)，保護器件免遭(zao)浪涌(yong)電(dian)(dian)(dian)(dian)(dian)流(liu)損壞。

PSW-系列設計(ji)了(le)可(ke)(ke)調(diao)斜(xie)率功能(neng)，用(yong)戶可(ke)(ke)以設置輸(shu)出(chu)電(dian)(dian)壓或輸(shu)出(chu)電(dian)(dian)流(liu)(liu)的(de)上升時(shi)(shi)(shi)間(jian)(由(you)低(di)電(dian)(dian)平(ping)變為(wei)高(gao)電(dian)(dian)平(ping))和(he)下降(jiang)時(shi)(shi)(shi)間(jian)(由(you)高(gao)電(dian)(dian)平(ping)變為(wei)低(di)電(dian)(dian)平(ping))。當電(dian)(dian)壓或電(dian)(dian)流(liu)(liu)準(zhun)位變化(hua)時(shi)(shi)(shi)，可(ke)(ke)調(diao)斜(xie)率有(you)利于待測物的(de)特性驗(yan)證(zheng)。通(tong)常情況下，生(sheng)產(chan)測試照明裝置和(he)大型電(dian)(dian)容時(shi)(shi)(shi)會在輸(shu)出(chu)打開瞬(shun)間(jian)引發浪涌電(dian)(dian)流(liu)(liu)，這嚴重縮(suo)短了(le)DUT壽(shou)命。為(wei)了(le)避免(mian)浪涌電(dian)(dian)流(liu)(liu)破壞強電(dian)(dian)流(liu)(liu)器件(jian)，在開關瞬(shun)間(jian)光滑和(he)緩慢的(de)電(dian)(dian)壓傳輸(shu)可(ke)(ke)以顯(xian)著減少浪涌電(dian)(dian)流(liu)(liu)，保護器件(jian)免(mian)遭大電(dian)(dian)流(liu)(liu)損(sun)壞。

PSW-系列提供(gong)OVP和(he)OCP保護，保護電平默認為(wei)額定輸(shu)出電壓/電流的110%。一旦超過預(yu)設值(zhi)，輸(shu)出立刻(ke)關閉。PSW-系列標(biao)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(chi)LabView驅動和(he)數據記錄PC軟件。后(hou)面(mian)板的模擬控(kong)制/監控(kong)接口(kou)，可以外部控(kong)制電源(yuan)開(kai)/關和外部監控輸(shu)出電壓和電流。
