功能说明

DS200DMCBG1AKG 是通用电气制造和设计的电源板。它是用于 IGBT 驱动应用的 EX2000 系列的一部分。EX2000 对该板的用途与驱动器的用途不同。括号中的斜体用于指示与 EX2000 应用程序不同的信息。电源板通过从控制电源变压器 (CPT) 接收 38 和 115 V 交流 (24 V 直流) 输入电源，为驱动器提供控制级电源，并为机柜风扇提供 115 V 交流电源 (NA)。板上有以下电路：

电枢电流和电压 (NA)

电机励磁电流 (NA)

交流线路电流

交流线路电压幅值和相序

电源

CPT 为 DCFB 板提供 38 V 交流电压或约 10%。（24 伏直流电）。对于未经调节的 24 V 直流输出，该电压经过全波整流和滤波。+24 V 和 -24 V 的输出额定电流分别为 3 A 和 1 A。

DCFB 板的稳压器从 24 V 直流电源汲取 15 V 直流电压。每个 15 V 直流输出能够处理 0.8 A，其中 0.25 A 可用于外部负载。

DCFB 板还使用 +24 V 直流电源来产生 +5 V 直流、4 A 输出。当 +5 V 直流电源受到调节时，2PL 上的 /PSEN 信号进入 TTL 低状态。

如果 +5 V 直流电源未调节，信号将进入高电平状态。当设置为高电平时，/PSEN 导致驱动控制卡的微处理器复位。

电枢电流反馈电路由电路板的隔离 +5 和 15 V 直流电源供电。

编号为 FU2 和 FU3 的保险丝可防止电源输出（7 A、2AG）发生短路。对于这些保险丝，保险丝熔断指示由发光二极管 (LED) CR51 和 CR55 提供。保险丝 FU1（1/2 A，2AG）保护 115 V 交流输出。

Function description

The DS200DMCBG1AKG is a power board manufactured and designed by General Electric. It is part of the EX2000 series for IGBT drive applications. The use of the EX2000 for the board is different from the use of the drive. The italics in parentheses are used to indicate information that is different from the EX2000 application. The power supply board provides control level power to the driver by receiving 38 and 115 V AC (24 V DC) input power from the control power transformer (CPT) and 115 V AC power (NA) to the cabinet fan. There are the following circuits on the board:

The power supply board provides control level power to the driver by receiving 38 and 115 V AC (24 V DC) input power from the control power transformer (CPT) and 115 V AC power (NA) to the cabinet fan. There are the following circuits on the board:

Power source

The CPT provides 38 V AC voltage or about 10% to the DCFB board. (24 volts DC). For an unregulated 24 V DC output, this voltage is rectified and filtered by full wave. The output current ratings for +24 V and -24 V are 3 A and 1 A respectively.

The DCFB board's voltage regulator draws 15 V DC from a 24 V DC supply. Each 15 V DC output is capable of handling 0.8A, of which 0.25A can be used for external loads.

The DCFB board also uses A +24 V DC power supply to produce a +5 V DC, 4 A output. When the +5 V DC power supply is regulated, the /PSEN signal on the 2PL enters the TTL low state.

If the +5 V DC power supply is not adjusted, the signal will enter a high level state. When set to high power level, /PSEN causes the microprocessor of the drive control card to reset.

The armature current feedback circuit is powered by isolated +5 and 15 V DC supplies on the board.

The fuses, numbered FU2 and FU3, prevent short circuits in the power output (7A, 2AG). For these fuses, fuse blowout indications are provided by light emitting diodes (leds) CR51 and CR55. The fuse FU1 (1/2 A, 2AG) protects 115 V AC output.
