style="text-indent:25px">模塊電源不允許長期處于滿負荷工作狀態(tài)。線性電源的使用率，應控制在60％以內；開關電源的使用率．應控制在80％以內。否則有可能造成模塊電源人為的早期失效。對于某些模塊電源，廠家出廠時在于可調端子(ADJ)間接有固定電阻。使用時須用戶自配相應阻值的電位器，以取代該固定電阻。但要注意，當可調端子間處于開路狀態(tài)時，決不允許加載。為了充分散熱，模塊電源宜安裝在空氣對流較好的位置。需用散熱器的模塊電源，其背板必須均勻涂抹導熱硅脂，并和散熱器緊密貼合，并加以緊固。一般要求線性電源工作電流在4 A以上，或開關電源工作電流在7 A以上時．應加裝強制風冷。此外，在模塊電源外殼上不允許放置其他物品。模塊電源一般適用于以阻性為主的負載，若需要應用在以容性為主或感性為主的負載時。應事先協(xié)議訂貨。寶山區(qū)DCDC電源模塊定制一般模塊電源有較小負載限制。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">對有TRIM或ADJ(可調節(jié)1輸出引腳的模塊電源，可通過電阻或電位器對輸出電壓進行一定范圍內的調節(jié)，調節(jié)范圍一般為±10％。對TRIM輸出引腳，將電位器的中心與TRIM相連，在所有+S、-S管腳的模塊中，其他兩端分別接+S、-S。沒有+S、-S時，將兩端分別接到相應主路的輸出正負極(+S接+ ，-S接-UIN)，然后調節(jié)電位器即可。電位器的阻值一般選用5～10 kΩ比較合適。對ADJ輸出引腳．分為輸入邊調節(jié)與輸出邊節(jié)。輸出邊調節(jié)與TRIM引腳的調節(jié)方式一樣。輸入邊調節(jié)只能上調輸出電壓．此時將電位器的其中一端與中心相接，另一端接輸入端的地。一般模塊電源都有內置濾波器，能滿足一般電源應用的要求。如果需要更高要求的電源系統(tǒng)，應增加輸入濾波網(wǎng)絡?？梢圆捎肔C或Ⅱ型網(wǎng)絡，但應注意盡量選擇較小的電感和較大的電容。為了防止輸人電源瞬態(tài)高壓損壞模塊電源，建議用戶在輸人端接瞬態(tài)吸收二極管并配合保險絲使用．以確保模塊在安全的輸入電壓范圍之內。為了降低共模噪聲，可以增加電容，一般選擇幾nF的高頻電容。</p><p style="text-indent:25px">電源模塊兒等級劃分，主要為**用級，商用級，工業(yè)級。不同等級對于工作環(huán)境的濕度，溫度，振動等要求也各有不同。我們常用的大都選擇30%～80%.因為這個功率范圍各功能發(fā)揮相對比較穩(wěn)定。通過相關質量認證的產(chǎn)品，用的芯片元器件和變壓器元器件質量會有保證，產(chǎn)品才具有較高的安全性能。選擇較好的dcdc電源模塊，才會抗干擾能力強，轉換率高，使用壽命長。科學的產(chǎn)品設計才會更靈活，合理。這就更利于安裝，應用和控制?，F(xiàn)階段的dcdc電源模塊分為：裸板，灌封。裸板dcdc電源模塊可以用直觀的方式看到，布局是否整齊有序，焊點干凈利落。灌封dcdc電源模塊雖然無法直觀查看內部情況，但安全性較高。模塊電源的PC B板與連接主機的供電線路之間有兩個連接點。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河南DCDC電源模塊,DCDC電源模塊"

style="text-indent:25px">設法降低模塊電源的溫升，模塊內部器件的工作溫度的高低直接影響模塊電源的壽命，器件溫度越低模塊壽命越長。在一定的工作條件下，模塊電源的損耗是一定的，但是可以通過改善模塊電源的散熱條件來降低其溫升，從而有效的延長其使用壽命。比如：50W以上的模塊電源必須安裝散熱器，散熱器的表面積越大越有利于散熱，且散熱器的安裝方向應盡量有利于空氣的自然對流，功率在150W以上除安裝散熱器以外還可以加裝扇強制風冷。此外在環(huán)境溫度較高或空氣流通條件較差的地方模塊須降額使用以減小功耗從而降低溫升，延長使用壽命。DC/DC變換器現(xiàn)已實現(xiàn)模塊化。河南DCDC電源模塊</p><p style="text-indent:25px">電路工作象限又可分為一象限、二象限、三象限、四象限。河南DCDC電源模塊</p><p style="text-indent:25px">冗余熱備份并聯(lián)將相同的模塊輸出端通過二極管后并聯(lián)可使輸出能力增強，以提高電源系統(tǒng)的可靠性。原則上如果配合相應輸出報警電路。將模塊放在可以拆卸的母線上。這樣，出現(xiàn)故障的模塊可以及時更換。用這種方法并聯(lián)的模塊，沒有量限制。串聯(lián)擴容將相同模塊輸出端串聯(lián)，可使輸出電壓倍增，功率也相應增加。而串聯(lián)輸出端須接二極管以進行保護。模塊電源的安裝和維護。由于模塊電源的類別、系列、規(guī)格品種很多，故其功能特性和物理特性不盡相同。因此在安裝、使用與維護方面也有不同。河南DCDC電源模塊</p><p
