　　0571-A-0328 机架的直流电源可以通过dc输入卡进入子机架，该电源可由用户从外部标称24V直流电源供电。 直流电源通过工程卡和子机架背板连接到机架中的所

　　有卡，并由dc输入卡上的保险丝保护。 有一个由两部分组成的接线板TB1，有助于在不断开每条连接导线的情况下移除卡。

　　0571-A-0328 为了防止在使用八个以上5704催化卡的安装中沿机架底板出现过大电流，建议控制卡通过相关的四继电器接口卡和仅用于为工程卡供电的DC输入卡

　　供电。

　　如果需要，备用电池电源也可以连接到辅助直流输入连接。

　　PSU和辅助连接通过二极管相互隔离。

　　DC输入卡还提供RFI过滤和反极性保护，

　　The dc power supply of the 0571-A-0328 rack can enter the sub-rack through the DC input card, and the power supply can be powered by the user from the external nominal 24V DC power supply. The DC power supply is connected to the station in the rack through the engineering card and the subrack backplane

　　There is a card and it is protected by a fuse on the dc input card. There is a two-part patch board, TB1, which helps to remove the card while constantly opening each connection wire.

　　0571-A-0328 To prevent excessive current along the chassis floor in installations using more than eight 5704 catalytic cards, it is recommended that the control card pass through the associated four-relay interface card and the DC input card used only to power the engineering card

　　Power on.

　　Backup battery power can also be connected to a secondary DC input connection if required.

　　The PSU and auxiliary connections are isolated from each other by diodes.

　　The DC input card also provides RFI filtering and reverse polarity protection,
