電源模塊輸出有電壓但電壓低于標(biāo)稱輸出值是測試過程中經(jīng)常遇到的問題，出現(xiàn)這種情況的原因無非有兩種，一是電源模塊為不良品或損壞，江蘇智慧路燈電-源銷售廠家，二是使用方法問題。下文天磁將重點(diǎn)討論使用方法導(dǎo)致的電源模塊輸出電壓低的情況。<span style="font-size:12px;">輸入電壓偏低是容易被忽略的情況，江蘇智慧路燈電-源銷售廠家，當(dāng)輸出有問題時我們應(yīng)該檢查輸入是否正常。對于輸入為定壓或?qū)拤旱碾娫茨K，江蘇智慧路燈電-源銷售廠家，當(dāng)輸入值偏低時將導(dǎo)致輸出值也偏低。當(dāng)然，這種情況是有限度的，對于一個特定的模塊來說，當(dāng)輸入電壓過低時將導(dǎo)致其不能工作，無輸出電壓。</span><span style="font-size:12px;">輸出過載是指負(fù)載工作功率大于電源模塊的額定輸出功率，過載情況下電源模塊的輸出電壓明顯被拉低。以ZY0505FS-1W為例，當(dāng)負(fù)載電流增大到300mA時，輸出電壓只有4.5V。持續(xù)過載將影響到電源模塊的工作效率、穩(wěn)定性以及散熱情況，導(dǎo)致模塊使用壽命減少。若是過載導(dǎo)致的輸出電壓過低，則需要提升電源模塊的輸出功率，可以選擇2W或3W的模塊。</span>
