style="text-indent:25px">為什么很多設(shè)備功率要求不大，卻選擇大功率的電源模塊?電源檢測是綜合電源模塊在較大功率各式各樣負荷的具體表現(xiàn)，這包含了輕負荷及載滿等檢驗。大功率電源模塊比低輸出功率的劃得來嗎?價格的差距是由設(shè)計、結(jié)構(gòu)、用材等特性上的不一樣所影響的，一些用材好、效率性高的、功效好的模塊電源必然是會比差點兒的貴一點兒。由于效率較低，溫度較高，將會導致電源模塊損壞或使用壽命大幅度減少，一般為了正常運用，推薦另加散熱。模塊電源效率越高，體現(xiàn)能量傳輸?shù)膿p耗越小，而損耗主要的表達方式是發(fā)熱，發(fā)熱小的操作溫度低。一般輸出工作頻率越低，其體積越大，發(fā)熱量越大，輸出紋波越大。在參數(shù)相近的情況下，電源模塊體積越大，散熱特性越高，工作溫度越低。普陀區(qū)大功率電源模塊哪家強</p></p><br
