DataMate3000 系統(tǒng)是一種小型的精密環(huán)境控制系統(tǒng)，專為電子設(shè)備的冷卻而設(shè)計(jì)，適用于設(shè)備室或計(jì)算機(jī)房的環(huán)境控制。具有高可靠性，從而能保證精密設(shè)備諸如敏感設(shè)備、工業(yè)過程設(shè)備、通信設(shè)備和計(jì)算機(jī)等設(shè)備擁有一個(gè)合理的運(yùn)行環(huán)境。

該系統(tǒng)目前室內(nèi)機(jī)有兩個(gè)系列：標(biāo)準(zhǔn)系列和S系列。標(biāo)準(zhǔn)DME3000包括7.5kW、12.5kW兩個(gè)冷量檔的機(jī)組，主要應(yīng)用于380V三相配電的場合；DME3000 S系列則包括5.5kW、7.5kW兩種制冷量的機(jī)組，主要針對220V單相配電場合。客戶可以根據(jù)機(jī)房的實(shí)際情況靈活選擇。

該系統(tǒng)目前室外機(jī)同樣有兩個(gè)系列，標(biāo)準(zhǔn)型和低溫LeeTemp型兩種室外機(jī)，其中低溫LeeTemp型室外機(jī)適用于較標(biāo)準(zhǔn)型更低的環(huán)境溫度。

系統(tǒng)采用分體落地式結(jié)構(gòu)，由室內(nèi)機(jī)和室外機(jī)兩部分構(gòu)成。室外機(jī)為風(fēng)冷式冷卻。

系統(tǒng)標(biāo)準(zhǔn)配置有制冷組件，可以對環(huán)境溫度進(jìn)行精確控制。另外提供加熱器和加濕罐選配件，可以對環(huán)境濕度進(jìn)行精密控制。如果設(shè)備僅用于制冷，則無需選配加熱器和加濕罐。

DataMate3000系統(tǒng)具有微處理控制器，可根據(jù)程序的設(shè)定值和室內(nèi)環(huán)境條件，自動切換所需的功能（制冷或制熱、除濕或加濕）。

選配艾默生UPS電源注意5因素

確定所需艾默生UPS電源的容量：計(jì)算所有的負(fù)載總和S=S1+S2+……+Sn單位：VA。選取UPS的容量≥S÷0.8（考慮UPS的抗沖擊能力及擴(kuò)容需要）。

確定所需艾默生UPS電源的類型：根據(jù)負(fù)載對輸出穩(wěn)定度、切換時(shí)間、輸出波形確定是選擇在線式、在線互動式、后備式。在線式UPS的輸出穩(wěn)定度、瞬間響應(yīng)能力比另外兩種強(qiáng)，對非線性負(fù)載的適應(yīng)能力也較強(qiáng)。對一些較精密的設(shè)備及較重要的設(shè)備要求采用在線式UPS。如果要使用發(fā)電機(jī)配短延時(shí)UPS，推薦用在線式UPS，因?yàn)槠胀òl(fā)電機(jī)的電壓及頻率穩(wěn)定性較差，用在線互動式及后備式可能導(dǎo)致工作不正常。某些品牌的UPS（在線式）不能與發(fā)電機(jī)匹配，會轉(zhuǎn)旁路供電，購買時(shí)要了解清楚。

確定所需電池后備時(shí)間：根據(jù)掉電后，設(shè)備所需的工作時(shí)間而定。長延時(shí)型的電池其成本可能超過UPS主機(jī)本身。由于電池的高價(jià)值，出現(xiàn)較多的仿冒品，要選擇信譽(yù)度高的供貨商，這對UPS系統(tǒng)的可靠性很關(guān)鍵。

附加功能：為了提高系統(tǒng)的可靠性，建議采用艾默生UPS電源冗余系統(tǒng)，可以考慮串聯(lián)熱備份或并聯(lián)熱冗余。小容量的艾默生UPS電源（1~2KVA）還可以選用冗余開關(guān)?？梢赃x用遠(yuǎn)程監(jiān)控面板，實(shí)現(xiàn)在遠(yuǎn)端監(jiān)視和控制UPS的工作?？梢赃x用監(jiān)控軟件，實(shí)現(xiàn)計(jì)算機(jī)和UPS之間的智能化管理。可以選用網(wǎng)絡(luò)適配器，實(shí)現(xiàn)UPS的網(wǎng)絡(luò)化管理（基于SNMP）。在某些多雨多雷地區(qū)，可以配用防雷器。

售后服務(wù)：由于艾默生UPS電源較笨重，而且大容量機(jī)型接線較復(fù)雜，需要上門維護(hù)，所以要選擇售后服務(wù)質(zhì)量較好的供貨商?？梢詮男抛u(yù)度、技術(shù)實(shí)力、服務(wù)機(jī)構(gòu)、維修備件等多方面進(jìn)行考察。

由于供電網(wǎng)絡(luò)和負(fù)載的復(fù)雜性以及自然界雷擊、地電等的影響，供給負(fù)荷的交流電并不是    穩(wěn)定的標(biāo)準(zhǔn)正弦波，會出現(xiàn)各種不良現(xiàn)象，專家們將這些市電問題分類如下：  

   1.持續(xù)的高壓或低壓（由電力變壓器的調(diào)節(jié)能力差引起，負(fù)載重時(shí)，電壓降低）； 

   2.艾默生UPS電源浪涌（大型負(fù)載設(shè)備關(guān)閉或雷擊引起）：電壓高于是110%額定值，持續(xù)一個(gè)或多個(gè)周波。    3.波形下陷(大型負(fù)載設(shè)備空然啟動、電網(wǎng)切換):電壓80-85%額定值,持續(xù)一個(gè)或多個(gè)周波； 

   4.艾默生UPS電源高壓尖脈沖（由閃電、電子開關(guān)的工作、電焊設(shè)備、靜電放電等引起），電壓峰值高達(dá)       6000V，持續(xù)時(shí)間一般為0.5-5個(gè)周波； 

   5.艾默生UPS電源高壓瞬態(tài)（由雷電、電子開關(guān)的工作、電焊設(shè)備、靜電放電等引起）：電壓峰值高達(dá)     20000V，持續(xù)時(shí)間為0.5-5個(gè)周波； 

   6.諧波電子干擾（由電動機(jī)、繼電器、廣播設(shè)備、無線通信設(shè)備、微波通信設(shè)備、電焊機(jī)等      產(chǎn)生的RFI，EMI）； 

   7.頻率漂移（小水電，發(fā)電機(jī)造成）； 

   8.斷電（空氣開關(guān)跳閘，電子配電盤故障）：零電壓持續(xù)2個(gè)周波以上。 

     對于精密負(fù)載設(shè)備來講，如金融系統(tǒng)的電腦網(wǎng)絡(luò)、證券公司的交易電腦、微波通信、醫(yī)療      設(shè)備、工業(yè)控制儀器等，上述市電問題會引起數(shù)據(jù)丟失、設(shè)備壞或死機(jī)、停止工作等，影響用戶的正常工作。

China's new energy automobile market can be said to be growing faster and faster, the reason for rapid development is largely due to the state's subsidy policy for new energy automobiles. With the strong support of the government, new energy automobiles are advancing rapidly, and the pursuit of "endurance mileage" by automobile enterprises is also increasing. The core component of new energy automobiles, "batteries" are also "survival of the fittest", and ternary lithium batteries are "survival of the fittest". It has gradually been widely used in new energy vehicles.

Is it possible for lithium iron phosphate batteries to retrogress when subsidies go down?

But with the substantial reduction of the subsidy policy in 2018, can lithium iron phosphate batteries, which were often used in the past, replace ternary lithium batteries and become the "darling" of new energy vehicles? I think the possibility is small, but at least in large buses and public transport, lithium iron phosphate batteries will still be widely used.

Is it possible for lithium iron phosphate batteries to retrogress when subsidies go down?

In the current market, most new energy vehicles mainly use lithium-ion batteries, lithium iron phosphate batteries and lithium manganate batteries. By contrast, what are the advantages of lithium iron phosphate batteries to support its retrograde attack?

Ternary lithium battery

The advantages of ternary lithium batteries are high energy density, good cycle performance and long range. They are more suitable for the future development trend of new energy automobile batteries, and suitable for Northern weather. The batteries are more stable in low temperature environment. However, its biggest disadvantage is that lithium ternary materials are unstable, easy to decompose at about 200 degrees, and electrolyte will burn rapidly in high temperature environment, which is why some new energy vehicles are easy to natural after collision.

But for many consumers, the mileage of new energy vehicles is still a problem they worry about, so whether subsidized or not, consumers hope that the mileage of electric vehicles can be longer. On the contrary, whether subsidized or not, automobile manufacturers certainly hope that their electric vehicle mileage can be bigger and better, after all, consumers will buy it. Single, so the advantage of ternary lithium batteries is very important at this time, which is why many manufacturers are willing to choose ternary lithium batteries.

Is it possible for lithium iron phosphate batteries to retrogress when subsidies go down?

Lithium iron phosphate battery

The greatest advantage of lithium iron phosphate batteries is safety and stability. It is the safest cathode material for lithium-ion batteries at present, and its cycle life can reach more than 2000 times, which is longer than that of ternary lithium-ion batteries. But its disadvantage is low energy density and low temperature resistance. It not only has low life, but also has low discharge efficiency. In addition, the volume is large and heavy, which will occupy a lot of space in the car. So this kind of battery with higher safety but lower energy density is generally used in public transportation. However, for household cars, they are generally less used nowadays.

Is it possible for lithium iron phosphate batteries to retrogress when subsidies go down?

Lithium manganate battery

Lithium manganate batteries are the mainstream power batteries in the past two years, but with the pursuit of mileage, lithium manganate batteries are gradually surpassed by ternary lithium batteries. Lithium manganate batteries are the cheapest among the three batteries, with high operating voltage, high rate performance and good low temperature performance. Their disadvantages are low energy density, general service life, especially poor high temperature cycle performance, and medium safety and stability.
