PSW-系(xi)列(lie)的(de)(de)C.V/C.C優先選擇模(mo)(mo)式(shi)能夠(gou)很好的(de)(de)保護待測(ce)(ce)物(wu)。當輸(shu)出(chu)開啟(qi)時(shi)，傳統(tong)電(dian)(dian)(dian)源(yuan)通常處于(yu)C.V模(mo)(mo)式(shi)，這會瞬(shun)間(jian)給電(dian)(dian)(dian)容性負(fu)載或強電(dian)(dian)(dian)流(liu)(liu)負(fu)載帶來一個較大的(de)(de)浪涌(yong)電(dian)(dian)(dian)流(liu)(liu)。以(yi)LED的(de)(de)I-V曲線驗證為例，使用傳統(tong)電(dian)(dian)(dian)源(yuan)就難(nan)以(yi)完成測(ce)(ce)量工作(zuo)。C.V模(mo)(mo)式(shi)下連接(jie)LED與(yu)電(dian)(dian)(dian)源(yuan)，打(da)開輸(shu)出(chu)，當電(dian)(dian)(dian)壓超過LED正向電(dian)(dian)(dian)壓時(shi)，電(dian)(dian)(dian)流(liu)(liu)突(tu)(tu)然(ran)增大并(bing)超過預設限流(liu)(liu)值。由(you)于(yu)偵(zhen)測(ce)(ce)到(dao)浪涌(yong)電(dian)(dian)(dian)流(liu)(liu)，電(dian)(dian)(dian)源(yuan)由(you)C.V模(mo)(mo)式(shi)轉換(huan)為C.C模(mo)(mo)式(shi)。雖然(ran)模(mo)(mo)式(shi)轉換(huan)后電(dian)(dian)(dian)流(liu)(liu)逐漸(jian)穩(wen)定(ding)，但(dan)C.V和(he)C.C相交處的(de)(de)尖峰電(dian)(dian)(dian)流(liu)(liu)可(ke)能會造成待測(ce)(ce)物(wu)損壞(huai)。然(ran)而，PSW-系(xi)列(lie)在輸(shu)出(chu)開啟(qi)瞬(shun)間(jian)，能優先運行(xing)在C.C模(mo)(mo)式(shi)，避(bi)免(mian)突(tu)(tu)發的(de)(de)尖峰電(dian)(dian)(dian)流(liu)(liu)，保護器件免(mian)遭(zao)浪涌(yong)電(dian)(dian)(dian)流(liu)(liu)損壞(huai)。

PSW-系列設(she)計了可(ke)調斜(xie)率功能，用戶(hu)可(ke)以設(she)置(zhi)輸(shu)出電(dian)(dian)(dian)壓或(huo)輸(shu)出電(dian)(dian)(dian)流(liu)的(de)(de)(de)上(shang)升時(shi)間(由(you)低電(dian)(dian)(dian)平(ping)變(bian)為高電(dian)(dian)(dian)平(ping))和(he)(he)下降時(shi)間(由(you)高電(dian)(dian)(dian)平(ping)變(bian)為低電(dian)(dian)(dian)平(ping))。當電(dian)(dian)(dian)壓或(huo)電(dian)(dian)(dian)流(liu)準位變(bian)化時(shi)，可(ke)調斜(xie)率有利(li)于待(dai)測物的(de)(de)(de)特性驗證(zheng)。通常(chang)情況下，生產測試照明裝置(zhi)和(he)(he)大(da)型電(dian)(dian)(dian)容時(shi)會在輸(shu)出打開(kai)(kai)瞬間引發浪涌電(dian)(dian)(dian)流(liu)，這(zhe)嚴重縮短了DUT壽命。為了避(bi)免浪涌電(dian)(dian)(dian)流(liu)破壞強電(dian)(dian)(dian)流(liu)器件，在開(kai)(kai)關瞬間光滑和(he)(he)緩慢(man)的(de)(de)(de)電(dian)(dian)(dian)壓傳輸(shu)可(ke)以顯著(zhu)減少浪涌電(dian)(dian)(dian)流(liu)，保護器件免遭(zao)大(da)電(dian)(dian)(dian)流(liu)損(sun)壞。

PSW-系列提(ti)供(gong)OVP和OCP保護(hu)，保護(hu)電(dian)(dian)平默(mo)認為額定輸出(chu)電(dian)(dian)壓/電(dian)流的110%。一(yi)旦超過預設(she)值，輸出立刻關(guan)閉。PSW-系(xi)列標配USB Host/Device、LAN接口和GPIB-USB及(ji)RS232-USB選(xuan)配接口，所有接(jie)口均支持LabView驅動和數據記錄PC軟件(jian)。后面板(ban)的模擬控制(zhi)/監控接(jie)口，可以(yi)外部控制(zhi)電源(yuan)開/關和(he)外部監控(kong)輸出(chu)電壓和(he)電流(liu)。
