PSW-系列是一款單路輸出、多量程可編程開關(guān)直流電源，，最大功率1080W。該系列涵蓋15種機(jī)型，提供30V、80V、160V、250V和800V的額定電壓和360W、720W和1080W的最大輸出功率。多量程操作可以靈活有效的設(shè)置電壓和電流。用戶最多能串行連接2臺(tái)或并行連接3臺(tái)PSW電源，這種提供更高輸出電壓或電流的連接能力極大的擴(kuò)展了它的應(yīng)用范圍。靈活的多量程操作和串/并聯(lián)連接，您無需再花費(fèi)資金購買多種電源產(chǎn)品，，PSW-系列完全可以滿足不同層次的電源需求。
PSW-系列的C.V/C.C優(yōu)先選擇模式能夠很好的保護(hù)待測物。當(dāng)輸出開啟時(shí)，傳統(tǒng)電源通常處于C.V模式，這會(huì)瞬間給電容性負(fù)載或強(qiáng)電流負(fù)載帶來一個(gè)較大的浪涌電流。以LED的I-V曲線驗(yàn)證為例，使用傳統(tǒng)電源就難以完成測量工作。C.V模式下連接LED與電源，打開輸出，當(dāng)電壓超過LED正向電壓時(shí)，，電流突然增大并超過預(yù)設(shè)限流值。由于偵測到浪涌電流，電源由C.V模式轉(zhuǎn)換為C.C模式。雖然模式轉(zhuǎn)換后電流逐漸穩(wěn)定，但C.V和C.C相交處的尖峰電流可能會(huì)造成待測物損壞。然而，PSW-系列在輸出開啟瞬間，能優(yōu)先運(yùn)行在C.C模式，避免突發(fā)的尖峰電流，保護(hù)器件免遭浪涌電流損壞。
PSW-系列設(shè)計(jì)了可調(diào)斜率功能，用戶可以設(shè)置輸出電壓或輸出電流的上升時(shí)間(由低電平變?yōu)楦唠娖?和下降時(shí)間(由高電平變?yōu)榈碗娖?。當(dāng)電壓或電流準(zhǔn)位變化時(shí)，，可調(diào)斜率有利于待測物的特性驗(yàn)證。通常情況下，，生產(chǎn)測試照明裝置和大型電容時(shí)會(huì)在輸出打開瞬間引發(fā)浪涌電流，這嚴(yán)重縮短了DUT壽命。為了避免浪涌電流破壞強(qiáng)電流器件，在開關(guān)瞬間光滑和緩慢的電壓傳輸可以顯著減少浪涌電流，保護(hù)器件免遭大電流損壞。
PSW-系列提供OVP和OCP保護(hù)，，保護(hù)電平默認(rèn)為額定輸出電壓/電流的110%。一旦超過預(yù)設(shè)值，，輸出立刻關(guān)閉。PSW-系列標(biāo)配USB Host/Device、LAN接口和GPIB-USB選配接口，，所有接口均支持LabView驅(qū)動(dòng)和數(shù)據(jù)記錄PC軟件。后面板的模擬控制/監(jiān)控接口，可以外部控制電源開/關(guān)和外部監(jiān)控輸出電壓和電流。
