花已枯至少你还有我 08-04 10:50

监控摄像机和电源距离50米远也可以使用12v供电，只要使用的电源线线径合适，电源适配器功率足够，不会有不良影响。1、采用集中供电时供电端（开关电源）和受电端（摄像机）的距离，要根据使用的电源线规格严格控制；2、开关电源额定功率要充足，不能使用虚标功率的电源；3、集中供电由于直接使用DC12V供电，线损较大，因此不宜使用非国标电线传输。

我要的无非是你一直在 08-04 10:58

则，家装用线普遍都是2，安全载流32A，完全满足，电流

陪我从懵懂无知到淡然沉静 08-04 11:06

55W/12V

说好了不分开 08-04 11:15

4.5A.5平方铜线安全载流是可以计算的，如果灯是55W

空扰寡人 08-04 11:23

25米用正规线材没有问题

1、灯带需要配置专用LED镇流桥插头才可以使用，灯带不配置插头是不可以使用。2、灯带插头是根据您的段数来配置，需要几段灯带，就需要配置对应的插头。3、用12V直流也许加个稳压电容和恒流二极管能点亮，或者买个能和灯匹配的12V直流输入的恒流驱动电路，灯是12V，功率4.8W，电流大概就是400MA，需要一个12V输出电压，电流大概400MA左右的恒流电源。4、家装用的220V电源的LED灯带，直接买专门为电脑机箱设计的LED灯带，插在机箱电源的大4P接口上就能用。
