PS-x 系列電源用于(yu)將 230Vac 或(huo) 24Vac 轉(zhuan)換為穩(wen)定的(de)(de) 24Vdc 輸出，提(ti)供保護、自(zi)診斷和自(zi)檢功能。具有過(guo)流和過(guo)壓保護、各種條件的(de)(de) LED 指示(shi)、用于(yu)輸入丟失(shi)的(de)(de)可選警報繼電器輸出和 PCB 上的(de)(de)復(fu)位按鈕。

它們適用于需要(yao)為傳(chuan)感(gan)器或 IO 模塊提供輔助電源的(de)應用。

LED指示

打開

當 PSU 通電時，LED 將呈橙色常亮(liang)顯示約 0.5 秒。（如果在(zai)加電過(guo)程(cheng)中按下復(fu)位按鈕(niu)，它會在(zai)這一(yi)步保(bao)持(chi)裝置(zhi)。）大(da)約 0.5 秒后，輸(shu)出被啟(qi)用并(bing)且警報(bao)繼電器關閉。該狀態(tai)保(bao)持(chi) 5 秒，或直到輸(shu)出電壓達到22.0Vdc。

當輸出電(dian)壓(ya)(ya)在(zai)范圍(wei)內時，繼電(dian)器(qi)保持閉合，并且 LED 顯示(shi)穩(wen)定的綠色。如果未達到最小(xiao)電(dian)壓(ya)(ya)，則輸出關(guan)閉，繼電(dian)器(qi)打開。LED 呈橙色長短閃爍，直到按下(xia)復位按鈕。

復位按鈕

每當按(an)下復位(wei)按(an)鈕時(shi)，LED 呈橙色常亮，輸出關閉，繼電器(qi)打(da)開。

輸出超出限制

如果(guo)輸(shu)出電(dian)(dian)(dian)(dian)壓(ya)(ya)低(di)于 22.0Vdc，LED 會(hui)短(duan)(duan)(duan)時閃爍(shuo)橙色(se)。繼(ji)電(dian)(dian)(dian)(dian)器(qi)保持關(guan)閉(bi)(bi) 4 秒。如果(guo)輸(shu)出電(dian)(dian)(dian)(dian)壓(ya)(ya)足(zu)夠(gou)(gou)(gou)低(di)足(zu)夠(gou)(gou)(gou)長(chang)時間(jian)，輸(shu)出電(dian)(dian)(dian)(dian)壓(ya)(ya)關(guan)閉(bi)(bi)，繼(ji)電(dian)(dian)(dian)(dian)器(qi)打開，LED 呈橙色(se)長(chang)短(duan)(duan)(duan)閃爍(shuo)，直到按下復(fu)位按鈕。如果(guo)輸(shu)出電(dian)(dian)(dian)(dian)壓(ya)(ya)升(sheng)至(zhi) 25.0Vdc 以(yi)上，則 LED 以(yi)紅(hong)色(se)短(duan)(duan)(duan)-短(duan)(duan)(duan)-短(duan)(duan)(duan)閃爍(shuo)。繼(ji)電(dian)(dian)(dian)(dian)器(qi)保持關(guan)閉(bi)(bi) 1 秒。如果(guo)輸(shu)出電(dian)(dian)(dian)(dian)壓(ya)(ya)足(zu)夠(gou)(gou)(gou)高且(qie)持續時間(jian)足(zu)夠(gou)(gou)(gou)長(chang)，則輸(shu)出電(dian)(dian)(dian)(dian)壓(ya)(ya)關(guan)閉(bi)(bi)，繼(ji)電(dian)(dian)(dian)(dian)器(qi)打開，LED 呈紅(hong)色(se)長(chang)短(duan)(duan)(duan)短(duan)(duan)(duan)閃爍(shuo)，直到按下復(fu)位按鈕。
