机架驱动板 GE DS200ITXDG1ABA 通用工业系统

DS200ITXDG1ABA板被标记为动力制动缓冲板，是通用电气公司制造的Mark V系列的一部分。IXTD板所需的操作通过连接的电源/接口板(IMCP)的电路提供。当IMCP和IXTD板连接时，它们通过一个四针连接器连接。安装电路板时，它将安装在外部，其尺寸必须满足动态制动IGBT的最差开关要求。缓冲板的目的是用来限制IGBTs上的电压瞬变，并通过所有已知的传动操作条件。

DS200ITXDG1ABA板的另一个功能是调节IGBT栅极驱动器板的输出，使其能够匹配AT帧驱动器的电气特性。AT机架驱动有可变和恒定扭矩应用。可变扭矩应用的驱动额定输出电流为500臂。

DS200ITXDG1ABA板有三种连接器类型；汇流条I/O连接器、DBPL的输入连接器和板入扣连接器。所有这些连接器类型都有不同的管脚号、术语和描述。母线I/O连接器和插入式I/O连接器也有方向。与入扣I/O连接器相关的两个引脚的一个例子是E-6和E-9连接器，它们都是输出连接器。E-6连接器是DB IGBT门信号，E-9连接器是外部缓冲电阻的连接。

The DS200ITXDG1ABA plate is marked as a power brake buffer plate and is part of the Mark V series manufactured by General Electric. The operations required for the IXTD board are provided through the circuit of the connected power/interface board (IMCP). When the IMCP and IXTD boards are connected, they are connected through a four pin connector. When installing the circuit board, it will be installed externally and its size must meet the worst switch requirements for dynamic braking IGBT. The purpose of the buffer plate is to limit voltage transients on IGBTs and pass through all known transmission operating conditions.

Another function of the DS200ITXDG1ABA board is to adjust the output of the IGBT gate driver board to match the electrical characteristics of the AT frame driver. The AT rack drive has variable and constant torque applications. The rated output current of the variable torque application is 500 arms.

The DS200ITXDG1ABA board has three types of connectors; Bus I/O connectors, DBPL input connectors, and board in buckle connectors. All of these connector types have different pin numbers, terms, and descriptions. Bus I/O connectors and plug-in I/O connectors also have directions. An example of two pins related to the input I/O connector is the E-6 and E-9 connectors, both of which are output connectors. The E-6 connector is for the DB IGBT gate signal, and the E-9 connector is for the connection of external buffer resistors
