一、電源時序器和電源控制器的區別

1、電源時序器

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)時序(xu)(xu)器能夠(gou)按照由前級設(she)備(bei)到后級設(she)備(bei)逐個順序(xu)(xu)啟動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，關閉(bi)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)時則由后級到前級的順序(xu)(xu)關閉(bi)各(ge)類(lei)用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)設(she)備(bei)，這樣就(jiu)能有(you)效的統(tong)一(yi)管(guan)理和控制(zhi)各(ge)類(lei)用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)設(she)備(bei)，避(bi)免了人(ren)為的失(shi)誤(wu)操作(zuo)，同時又可(ke)減低用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)設(she)備(bei)在開關瞬間對(dui)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)網的沖擊，也避(bi)免了電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流對(dui)設(she)備(bei)的沖擊，確保了整個用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統(tong)的穩定。（自(zi)身(shen)對(dui)外接設(she)備(bei)進行智能控制(zhi)）

2、電源控制器

電(dian)(dian)源(yuan)控(kong)制器，可以(yi)(yi)發送(song)RS-232和(he)RS-485代碼(ma)，用電(dian)(dian)腦和(he)中控(kong)對(dui)設(she)備進行(xing)控(kong)制，如設(she)備開關(guan)，投影(ying)機(ji)延(yan)時關(guan)機(ji)，電(dian)(dian)動(dong)(dong)(dong)屏幕、電(dian)(dian)動(dong)(dong)(dong)窗(chuang)簾、電(dian)(dian)動(dong)(dong)(dong)吊架的升降控(kong)制等。（可以(yi)(yi)通過協議(yi)連(lian)接外部控(kong)制設(she)備對(dui)負(fu)載進行(xing)控(kong)制）

二、如何挑選電源時序器

1、穩壓性

時(shi)序器穩定運行(xing)(xing)的(de)(de)是系(xi)統可靠的(de)(de)前(qian)提，時(shi)序器經常不開(kai)機，或(huo)時(shi)不時(shi)有(you)一兩個通(tong)道不開(kai)，這樣再好系(xi)統都白搭。除(chu)本身運行(xing)(xing)可靠外，還需要(yao)有(you)一定的(de)(de)抗(kang)干(gan)擾(rao)能(neng)力(li)，對時(shi)序沖擊的(de)(de)干(gan)擾(rao)源(yuan)一部(bu)分來電源(yuan)外網，這部(bu)分干(gan)擾(rao)主要(yao)有(you)感(gan)應雷(lei)、電動機、日光燈等產生的(de)(de)浪(lang)涌(yong)和脈沖尖峰；另一部(bu)分是系(xi)統起動時(shi)，設備(bei)內部(bu)電源(yuan)充電或(huo)開(kai)關電源(yuan)造成的(de)(de)干(gan)擾(rao)。

2、測試時序器穩定性

首先給時(shi)序(xu)器上電，將時(shi)序(xu)器時(shi)序(xu)間隔時(shi)間設為(wei)1秒(miao)，然后起(qi)動時(shi)序(xu)啟動功能，在起(qi)動過程中開關房間內的日光燈或電鉆等，注意時(shi)序(xu)器不能有(you)(you)重啟或有(you)(you)通道(dao)不開的情(qing)況,這種方法(fa)要測(ce)試(shi)多次(ci)。如(ru)果有(you)(you)條件的可(ke)能用脈沖發生器向時(shi)序(xu)器供電市(shi)電（220V電）注入(ru)干(gan)擾(rao)脈沖，測(ce)試(shi)中分(fen)次(ci)增加干(gan)擾(rao)強度，以測(ce)試(shi)出被測(ce)時(shi)序(xu)器的抗干(gan)擾(rao)強度，一般來說要達到1KV(1000V)以上。

給時(shi)(shi)(shi)序(xu)器的(de)每個輸出都(dou)接上負(fu)載（最好是大(da)功率功放），如沒有(you)那么多負(fu)載，可以將(jiang)負(fu)載接到(dao)連續的(de)后幾路上（如CH12、11、10、9）。然后給時(shi)(shi)(shi)序(xu)器上電并起動(dong)時(shi)(shi)(shi)序(xu)起動(dong)功能（注意如時(shi)(shi)(shi)序(xu)間隔(ge)時(shi)(shi)(shi)間可調(diao)的(de)設(she)備(bei)，要將(jiang)間隔(ge)時(shi)(shi)(shi)間調(diao)整(zheng)到(dao)1秒），起動(dong)過(guo)程看(kan)時(shi)(shi)(shi)序(xu)器不(bu)能有(you)重啟或有(you)通(tong)道不(bu)開的(de)情況。

3、容量

系統整體的(de)(de)(de)電(dian)(dian)(dian)(dian)流需求是(shi)(shi)挑(tiao)選時(shi)(shi)序器(qi)容量的(de)(de)(de)標(biao)準，現市場有20A、30A、40A、50A電(dian)(dian)(dian)(dian)流的(de)(de)(de)可供挑(tiao)選；單路的(de)(de)(de)容量一般為(wei)10A或13A；現在有的(de)(de)(de)廠家吹自己使用(yong)30A的(de)(de)(de)繼電(dian)(dian)(dian)(dian)器(qi)，輸(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)流達30A，而輸(shu)(shu)出(chu)座卻使用(yong)的(de)(de)(de)是(shi)(shi)美式(shi)(shi)或萬能式(shi)(shi)插(cha)座，這種座的(de)(de)(de)額定電(dian)(dian)(dian)(dian)流是(shi)(shi)10A，有的(de)(de)(de)加厚彈片的(de)(de)(de)是(shi)(shi)13A。由(you)此(ci)看(kan)出(chu)輸(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)流是(shi)(shi)達不來(lai)到30A的(de)(de)(de)，大伙可以用(yong)30A的(de)(de)(de)負載測試一下；測試時(shi)(shi)用(yong)電(dian)(dian)(dian)(dian)流達10A的(de)(de)(de)負載，接(jie)到標(biao)稱(cheng)總容量電(dian)(dian)(dian)(dian)流，煮水4小時(shi)(shi)。電(dian)(dian)(dian)(dian)源引線表面溫(wen)度不能超60度，摸起來(lai)不燙手；時(shi)(shi)序器(qi)不能發出(chu)糊味。

4、可擴展

電源時(shi)序器(qi)輸出通(tong)道(dao)數(shu)分(fen)為4路(lu)(lu)(lu)、8路(lu)(lu)(lu)、10路(lu)(lu)(lu)、12路(lu)(lu)(lu)等(deng)、當設備的數(shu)量超(chao)過一臺時(shi)序器(qi)通(tong)道(dao)的數(shu)量時(shi)，就要(yao)擴展（級聯）使用了，選擇時(shi)要(yao)注(zhu)意擴展后能從第一路(lu)(lu)(lu)開到(dao)最后一路(lu)(lu)(lu)，還能從最后一路(lu)(lu)(lu)關到(dao)第一路(lu)(lu)(lu)。

5、功能

按(an)項目(mu)要求(qiu)挑選，如電(dian)平起動功(gong)能(neng)，RS232、RS485、TCP/IP控(kong)制(zhi)功(gong)能(neng)，狀態監控(kong)；時序間隔、常開配置功(gong)能(neng)；電(dian)源凈化、防浪涌(yong)、電(dian)壓、電(dian)流監測保護功(gong)能(neng)等。
