我們(men)在挑選車載式UPS的時候(hou)，通(tong)常需要考慮功(gong)率(lv)、負載以及輸出(chu)電(dian)(dian)壓等(deng)數值指(zhi)標。而這(zhe)次我們所要探討的既(ji)不是(shi)(shi)(shi)功(gong)率(lv)也不是(shi)(shi)(shi)負載，而是(shi)(shi)(shi)車載式UPS電(dian)(dian)源輸出(chu)電(dian)(dian)壓的指(zhi)標，一跟著小編一起來看看吧。

那么，車載式ups電源(yuan)的輸出電壓(ya)指標有哪些？

1、標稱輸出(chu)電(dian)壓值

單(dan)進(jin)單(dan)出(chu)或(huo)三進(jin)單(dan)出(chu)的UPS輸出(chu)電(dian)(dian)壓值(zhi)為220V；三進(jin)三出(chu)的UPS輸出(chu)電(dian)(dian)壓值(zhi)為380V，并采用三相三線制或(huo)三相四線制輸出(chu)方式

2、輸出電壓可調范圍

大丶中(zhong)容(rong)量(liang)UPS的輸(shu)出電(dian)壓從UPS的額定值(zhi)起(qi)最小可(ke)調±5%。小容(rong)量(liang)單相(xiang)UPS一般用撥盤調解法，輸(shu)出電(dian)壓的典型可(ke)調范(fan)圍(wei)為208/220/230/240V。

3、輸出電(dian)壓靜態穩定度

車(che)載(zai)(zai)式UPS在100%突然加丶減(jian)滿(man)載(zai)(zai)的時(shi)候(hou)或執(zhi)行市電(dian)(dian)旁路供(gong)電(dian)(dian)通(tong)道與逆變器供(gong)電(dian)(dian)通(tong)道轉換(huan)的時(shi)候(hou)，暑(shu)促互電(dian)(dian)壓的波(bo)(bo)動值。中、大(da)容量車(che)載(zai)(zai)式UPS的瞬態(tai)電(dian)(dian)壓波(bo)(bo)動值應小(xiao)于±5%，小(xiao)容量UPS的瞬態(tai)電(dian)(dian)壓波(bo)(bo)動值應小(xiao)于±6%-±8%.

4、輸(shu)出電壓動(dong)態(tai)響(xiang)應恢復時(shi)間

在輸入電(dian)(dian)壓(ya)為額定值，輸出為線(xian)性負(fu)載，輸出電(dian)(dian)流(liu)為零至額定電(dian)(dian)流(liu)或者由額定電(dian)(dian)流(liu)至零突(tu)變的時(shi)候，UPS輸出電(dian)(dian)壓(ya)恢復到穩壓(ya)精度范(fan)圍(wei)內所需要的時(shi)間，大多數UPS應(ying)該(gai)在10~30ms范(fan)圍(wei)之間。

5、輸(shu)出電壓頻(pin)率(lv)

車(che)載(zai)式(shi)(shi)UPS所(suo)以(yi)允(yun)許的市電(dian)(dian)同步(bu)跟(gen)蹤范(fan)圍，一般的大(da)(da)、中(zhong)容(rong)(rong)(rong)(rong)量(liang)(liang)的UPS為50Hz±(0.5~2)Hz；小(xiao)(xiao)(xiao)容(rong)(rong)(rong)(rong)量(liang)(liang)的UPS一般為50Hz±(0.5~3)Hz，而車(che)載(zai)式(shi)(shi)UPS所(suo)允(yun)許市電(dian)(dian)的同步(bu)跟(gen)蹤速率，大(da)(da)容(rong)(rong)(rong)(rong)量(liang)(liang)的UPS一般為0.1~1Hz/s；中(zhong)小(xiao)(xiao)(xiao)容(rong)(rong)(rong)(rong)量(liang)(liang)UPS一般為0.1~3Hz/S。另外當車(che)載(zai)式(shi)(shi)ups工作在逆(ni)變(bian)器輸(shu)出狀態時頻(pin)率穩定度，小(xiao)(xiao)(xiao)容(rong)(rong)(rong)(rong)量(liang)(liang)UPS一般為50Hz±0.1Hz；大(da)(da)、中(zhong)容(rong)(rong)(rong)(rong)量(liang)(liang)UPS一般為50Hz±（0.5~0.005）Hz。

6、輸出(chu)電(dian)壓波形積失(shi)真度

由于車載式(shi)ups用(yong)途(tu)不(bu)(bu)同，輸出電壓不(bu)(bu)一(yi)定是正弦(xian)波(bo)(bo)(bo)，也(ye)可(ke)以是方波(bo)(bo)(bo)或梯形(xing)波(bo)(bo)(bo)。后備(bei)式(shi)UPS輸出波(bo)(bo)(bo)形(xing)一(yi)般為方波(bo)(bo)(bo)，在(zai)線式(shi)UPS的輸出波(bo)(bo)(bo)形(xing)一(yi)般為正弦(xian)波(bo)(bo)(bo)。

總得來說，車載式UPS是專為車載系統而設計UPS，主要是為了提高供電系統的可靠性以及消除電網對于負載設備所造成的不良影響。所以對于車載式UPS的指標進行比對時要對于多個方面進行注意，比如說輸出電壓，過載能力以及切換時間等。如果您還有其他疑問，歡迎來電咨詢。
