PS-x 系列電(dian)源用(yong)于將(jiang) 230Vac 或 24Vac 轉換為穩定的 24Vdc 輸出，提供保(bao)護、自診斷和自檢功能。具有過(guo)(guo)流(liu)和過(guo)(guo)壓保(bao)護、各種(zhong)條件的 LED 指示(shi)、用(yong)于輸入丟(diu)失的可選警報繼電(dian)器輸出和 PCB 上(shang)的復(fu)位(wei)按鈕(niu)。

它們適用于需要為傳感器(qi)或 IO 模塊提供輔助電源(yuan)的應用。

LED指示

打開

當(dang) PSU 通電(dian)時，LED 將呈橙(cheng)色常亮顯示約 0.5 秒。（如果在(zai)加電(dian)過程中按(an)下復(fu)位(wei)按(an)鈕，它會(hui)在(zai)這一步保持(chi)裝置。）大(da)約 0.5 秒后，輸(shu)(shu)出(chu)被啟(qi)用并且警報繼電(dian)器關閉。該狀態保持(chi) 5 秒，或(huo)直到(dao)輸(shu)(shu)出(chu)電(dian)壓(ya)達到(dao)22.0Vdc。

當輸出電(dian)壓在范圍內(nei)時，繼(ji)電(dian)器保(bao)持閉合，并且(qie) LED 顯示穩定的綠色。如果未達到(dao)最小電(dian)壓，則輸出關閉，繼(ji)電(dian)器打開(kai)。LED 呈(cheng)橙(cheng)色長短閃爍，直到(dao)按下復位按鈕。

復位按鈕

每當按下復位按鈕(niu)時，LED 呈橙色常亮，輸出關閉，繼(ji)電器打開。

輸出超出限制

如果(guo)輸(shu)(shu)出電(dian)(dian)(dian)(dian)壓(ya)低于 22.0Vdc，LED 會(hui)短(duan)時閃(shan)爍(shuo)橙色(se)。繼(ji)電(dian)(dian)(dian)(dian)器保持(chi)關閉 4 秒。如果(guo)輸(shu)(shu)出電(dian)(dian)(dian)(dian)壓(ya)足(zu)(zu)夠(gou)低足(zu)(zu)夠(gou)長(chang)時間，輸(shu)(shu)出電(dian)(dian)(dian)(dian)壓(ya)關閉，繼(ji)電(dian)(dian)(dian)(dian)器打(da)開，LED 呈橙色(se)長(chang)短(duan)閃(shan)爍(shuo)，直(zhi)到按(an)(an)(an)下(xia)復(fu)位按(an)(an)(an)鈕(niu)。如果(guo)輸(shu)(shu)出電(dian)(dian)(dian)(dian)壓(ya)升至 25.0Vdc 以上，則(ze)(ze) LED 以紅(hong)色(se)短(duan)-短(duan)-短(duan)閃(shan)爍(shuo)。繼(ji)電(dian)(dian)(dian)(dian)器保持(chi)關閉 1 秒。如果(guo)輸(shu)(shu)出電(dian)(dian)(dian)(dian)壓(ya)足(zu)(zu)夠(gou)高且持(chi)續(xu)時間足(zu)(zu)夠(gou)長(chang)，則(ze)(ze)輸(shu)(shu)出電(dian)(dian)(dian)(dian)壓(ya)關閉，繼(ji)電(dian)(dian)(dian)(dian)器打(da)開，LED 呈紅(hong)色(se)長(chang)短(duan)短(duan)閃(shan)爍(shuo)，直(zhi)到按(an)(an)(an)下(xia)復(fu)位按(an)(an)(an)鈕(niu)。
