自帶(dai)電(dian)源集中(zhong)控制系統是指將源設備安裝在電源室和電池室中，并且通信功率被均勻地轉換并分配到每個通信設備的方式。

自帶電(dian)源(yuan)集(ji)(ji)中控制(zhi)(zhi)系統的(de)優點是(shi)統一控制(zhi)(zhi)和(he)管理供電(dian)方(fang)案，減(jian)少(shao)工程(cheng)電(dian)纜(lan)的(de)使用，美化工程(cheng)布線。但是(shi)，請注意(yi)，在使用集(ji)(ji)中式(shi)電(dian)源(yuan)解決方(fang)案時，應(ying)確保(bao)集(ji)(ji)中式(shi)電(dian)源(yuan)設(she)備的(de)總容量大于后續級別的(de)負(fu)載業務容量之和(he)。同(tong)時，還(huan)要考慮前端電(dian)纜(lan)的(de)線徑應(ying)滿足后端中所有(you)負(fu)載的(de)電(dian)流要求。

自帶電(dian)(dian)(dian)(dian)源集(ji)中(zhong)控制系統可以集(ji)中(zhong)管(guan)理電(dian)(dian)(dian)(dian)源以確保電(dian)(dian)(dian)(dian)能質量(liang)，還可以避免因區域性停(ting)電(dian)(dian)(dian)(dian)或分布式(shi)電(dian)(dian)(dian)(dian)源的不(bu)穩定(ding)而導致的停(ting)電(dian)(dian)(dian)(dian)或其他故障。它可以同(tong)時為多個(ge)直流供電(dian)(dian)(dian)(dian)設(she)備供電(dian)(dian)(dian)(dian)，省去了(le)麻煩和煩惱。

如果用戶正(zheng)在(zai)使用端口輸出12V電(dian)(dian)(dian)源。連接(jie)大量無線AP后(hou)，AC根本找不到(dao)該AP，因(yin)此AP不會通(tong)(tong)過(guo)抓包的(de)方式向(xiang)AC發送數據包。將(jiang)AP直接(jie)連接(jie)到(dao)AC，通(tong)(tong)信正(zheng)常，無法與(yu)原地通(tong)(tong)信。此時(shi)，可以得出結論，AC和AP之間沒有設備故障。因(yin)此，工程師懷疑電(dian)(dian)(dian)源問題是由自帶電(dian)(dian)(dian)源集(ji)中(zhong)控制(zhi)系統(tong)引起的(de)。那么(me)為什(shen)么(me)自帶電(dian)(dian)(dian)源集(ji)中(zhong)控制(zhi)系統(tong)不足？

自帶電(dian)(dian)(dian)源集(ji)中控制系(xi)統的電(dian)(dian)(dian)壓通常(chang)默認為(wei)12V，因此輸(shu)出(chu)功(gong)率取決于(yu)電(dian)(dian)(dian)流(liu)，范圍為(wei)20A，30A和40A。電(dian)(dian)(dian)流(liu)越(yue)大(da)，支(zhi)持的輸(shu)出(chu)功(gong)率就越(yue)高(gao)。電(dian)(dian)(dian)源電(dian)(dian)(dian)壓不(bu)足的直接原因是(shi)線(xian)(xian)路電(dian)(dian)(dian)阻太(tai)大(da)，導(dao)致線(xian)(xian)路電(dian)(dian)(dian)壓降相對較大(da)。材(cai)料，導(dao)線(xian)(xian)直徑和長度會影響電(dian)(dian)(dian)路的電(dian)(dian)(dian)阻。該怎么解決？

1.大(da)多數自帶電(dian)源集中控制系統(tong)都支持適當調整輸出(chu)電(dian)壓(ya)，在VADJ標記的位置，使用十字螺(luo)絲刀旋(xuan)轉輸出(chu)電(dian)壓(ya)。經(jing)過測(ce)試，將(jiang)電(dian)壓(ya)從12V調節至14V可以有效地將(jiang)電(dian)源距(ju)離延長約30％。

2.每個支持直流電源的TP-LINK AP都將帶有一個無源PoE模塊，更換自帶電源集中控制系統模式，然后使用該模塊進行供電。      //www.www69sihucomm.cn/
