style="text-indent:25px">智慧路燈解決方案采用世界前列技術的OFDMA（正交頻分多址調(diào)制技術）PLC收發(fā)芯片，可在嘈雜的環(huán)境中掃描和選擇比較好頻率完全冗余的靈活性和機會，非常適合在嘈雜的環(huán)境中使用，它可以有效地解決由于信號衰減，脈沖噪聲和線路阻抗變化而導致的電力線應用中常見的信號變化，可自動配置并自適應電源線的各種條件，從而在低壓電網(wǎng)中實現(xiàn)極為可靠和穩(wěn)健的通信。該芯片具有18個獨立通道，能夠在5KHz至500KHz的寬頻率范圍內(nèi)以高達54個載波頻率運行，并且配置了“雙保險”第19通道，LORA遠距離低功耗無線通信技術，使得通信穩(wěn)定性提高到一個非常良好的狀態(tài)。</p><p> 另一個是要根據(jù)負載的波動情況來確定，有的負載較穩(wěn)定，有的負載就波動較大，甚至于有的還會有空載、或滿載、或瞬間負載變大、或瞬間負載跌落的情況發(fā)生，若有這種問題，比較好與電源模塊廠家說明，確認其設計上已有必要的應對防護性設計措施，不是所有的電源都可以達到這個目標的。<span style="font-size:12px;">負載的類型也是一個影響因素。一般的模塊，其輸出是按照默認為阻性負載而設計的，如果負載是感性或容性負載，都需要與模塊廠家單獨說明，以便廠家出廠時的電源模塊內(nèi)部器件或參數(shù)稍作調(diào)整。</span><span style="font-size:12px;">電源模塊的開關頻率也是需要關注的，他決定了外接電源濾波器濾波參數(shù)（截止頻率、階次）的選擇。</span> </p> <p> <br /> 可以監(jiān)測產(chǎn)品工作條件更可以精確制定電源規(guī)格。</p><div style="width:100%;text-align: center;"><img

電源市場風起云涌，競爭日趨激烈，對于電子工程師，電源似乎已成一個隨處抓一模塊都可以滿足要求的時代。電源模塊選型沒那么簡單，它需要考慮很多問題。就好像：娛樂圈有陪睡潛規(guī)則、官場有送禮的潛規(guī)則、學術圈有師承人脈的潛規(guī)則、商界有關鍵崗位要用自己人的潛規(guī)則（如財務、門衛(wèi)）一樣…電子領域也有自己的潛規(guī)則，比如保險絲的標稱值1A，它是指@25度時候的指標，但如果您的設備工作在50度的話，保險絲的標稱值可就比1A變低，此溫度下的設計余量就要選大一點了。電感的1mH也不是什么時候都是1mH，它是@1kHz的時候，如果您把它用在1MHz的時候，加工商送來的1mH電感的值可就不是1mH，因為1M時電感線圈里的分布電容開始起不小的影響，會抵消掉一部分電感的作用。濾波器的插損IL=25dB，是@**MHz@Rs/RL=50歐姆（源阻抗和負載阻抗）的時候，而實際上，我們的濾波器使用場合，很難做到阻抗?jié)M足這個要求，因此25dB的插損就會大打折扣。磁珠、電容、二極管、電阻….都具有類似的潛規(guī)則，只是我們不太注意而已。我們說的就是電源模塊的潛規(guī)則。支持5路輸出，并具有PWM調(diào)光輸出（DALI可選）。天津深圳天磁科技有限公司電-源供應商家</p><p

style="text-indent:25px">性能”和“成本”是一對相愛相殺的冤家，讓多少工程師面臨兩難的選擇，多少辛辛苦苦做的方案，由于成本問題不得不放棄。是為了性能不顧成本？還是為了成本犧牲性能？怎樣平衡性能和成本，這是在產(chǎn)品設計中亙古不變的話題。對于同樣輸入輸出電壓的DC/DC電源模塊來說，輸出功率和工作溫度范圍是影響其成本的主要因素。電子器件工作溫度范圍一般分為：商業(yè)級（0~70℃）、工業(yè)級（-40~85℃）、車規(guī)級（-40~105℃）、軍品級（-55~125℃）等。由于溫度等級不同，對材料和制造工藝的要求不同，模塊成本就相差很大了。路燈電-源質(zhì)量商家</p></p><br
