A-B 1783-SFP100LX在全球動(dòng)力日趨嚴(yán)峻,能效標(biāo)準(zhǔn)越來越嚴(yán)苛的狀況下,下降電子設(shè)備的待機(jī)功耗顯得越來越首要和急迫。
電源作為電子體系的“心臟”,底子的電源功用現(xiàn)已不能滿意電子設(shè)備節(jié)能環(huán)保的需要。金升陽高效節(jié)能型
DC-DC寬壓R3代電源將給您帶來全新體會(huì)。
職業(yè)界電源模塊的運(yùn)用疑問
【運(yùn)用疑問1 :空載功耗過大而致使儲(chǔ)能供電體系續(xù)航時(shí)刻變短】
儲(chǔ)能體系的能量耗費(fèi)有兩種辦法:作業(yè)辦法和待機(jī)辦法。作業(yè)辦法時(shí),在確保體系具有相同功用的條件下,
能夠經(jīng)過下降各有些能耗來完結(jié)節(jié)能;而待機(jī)辦法則有所不相同,這些電路中的有些單元是持久供電的,以備
悉數(shù)體系隨時(shí)重啟、作業(yè)。比方,運(yùn)用DC/DC商品時(shí),最常見的供電辦法是運(yùn)用蓄電池供電,如BMS電池辦理體
系、超級(jí)電容供電體系等。這些體系中,設(shè)備大有些時(shí)刻作業(yè)在空載條件下,此時(shí)過大的空載輸入電流直接耗
費(fèi)了這些儲(chǔ)能體系的能量。
?
如今職業(yè)界輸出功率6W的電源模塊在24V輸入電壓狀況下,空載電流方針典型值大多為12~15mA擺布,比
照而言,金升陽R3代商品空載電流就十分小,典型值一般為4~5mA。在同一條件下測(cè)驗(yàn),R3代商品空載損耗大
幅下降,乃至低至0.12W。舉一個(gè)20AH蓄電池的運(yùn)用實(shí)例:咱們用蓄電池給DC/DC模塊電源供電時(shí),一般狀況下
空載輸入電流為15mA,電池的續(xù)航才干為1333.3H。假如要行進(jìn)蓄電池的續(xù)航時(shí)刻,那么有必要下降空載電流
方針。金升陽R3代電源模塊的空載電流為職業(yè)界的三分之一,那么續(xù)航的時(shí)刻將行進(jìn)三倍抵達(dá)4000H。因而,
R3代電源模塊大幅度行進(jìn)了蓄電池供電的續(xù)航時(shí)刻,下降了儲(chǔ)能體系的能耗。
其次,關(guān)于儲(chǔ)能體系處于待機(jī)狀況下,且悉數(shù)供電體系需一同兼容幾個(gè)不相同輸入電壓段的運(yùn)用,則格外
需要重視全電壓計(jì)劃內(nèi)的功耗均衡疑問。如今,在滿載條件下抵達(dá)高功率是十分盛行的,工程師在計(jì)劃時(shí)也是
十分重視,但疏忽了空載電流方針,以至于空載功耗乃至抵達(dá)2W。此時(shí),在待機(jī)辦法下儲(chǔ)能體系的能量轉(zhuǎn)化為
熱量的辦法開釋出去,構(gòu)成了動(dòng)力的糟蹋。金升陽R3代商品在全輸入電壓計(jì)劃內(nèi)的空載電流都比照均衡,方針
別離為:低壓輸入5~6mA,標(biāo)稱電壓輸入4~5mA,高壓輸入2~3mA,能夠確保在兼容幾個(gè)不相同輸入電壓段時(shí)
空載功耗的均衡運(yùn)用,防止糟蹋全體體系的待機(jī)能量。
金升陽R3代電源模塊以超低的空載功耗和全電壓計(jì)劃內(nèi)功耗均衡等特性,處理了體系長(zhǎng)時(shí)刻在空載條件下
作業(yè)而發(fā)作的能耗疑問,幫忙設(shè)備完結(jié)高效節(jié)能。
【運(yùn)用疑問2 :過火著重模塊的降額運(yùn)用然后致使外殼溫升相對(duì)較高】
大有些客戶在運(yùn)用模塊電源時(shí),習(xí)慣降額到10%~30%負(fù)載下運(yùn)用,他們以為這么降額運(yùn)用能夠行進(jìn)商品長(zhǎng)
時(shí)刻作業(yè)的牢靠性。本來不然,在電源模塊的實(shí)習(xí)運(yùn)用中,因?yàn)檩p負(fù)載功率較低,若長(zhǎng)時(shí)刻作業(yè)在輕負(fù)載條件
下,將致使自身損耗大,致使模塊外殼溫度增加,在多模塊運(yùn)用的場(chǎng)合或密閉場(chǎng)合中將致使模塊失效,無法徹
底滿意高牢靠性的運(yùn)用請(qǐng)求。
舉一個(gè)實(shí)習(xí)運(yùn)用的事例,某軍工客戶負(fù)載約1W,在運(yùn)用模塊時(shí)以為降額運(yùn)用可行進(jìn)商品牢靠性,所以選用
國(guó)內(nèi)某品牌6W電源模塊。在標(biāo)稱電壓輸入,輸出滿負(fù)載,25℃環(huán)境溫度下測(cè)驗(yàn), 測(cè)驗(yàn)該模塊的外殼溫度44度,
高溫85度條件下測(cè)驗(yàn)外殼溫度抵達(dá)103度?墒牵粼撃K繼續(xù)作業(yè)在高溫環(huán)境下,其牢靠性將會(huì)下降。
