DS200DCFBG1BLC 5 GE 多复杂电路系统

DS200DCFBG1BLC DCFB 板为直流驱动器或励磁器提供控制级电源，并提供 115 V 交流电，通常用于为机箱冷却风扇供电。DCFB 包括以下电路：

控制级电源（+5、±15 和 ± 24 V dc）

电动机或发电机励磁电源电路（SCR 模块除外）

电枢 SCR 栅极脉冲发生器的驱动器

电路 用于测量大量仪器的电路交流线路和直流电机或发电机信号，包括：

– 电枢电流和电压

– 励磁电流

– 交流线路电流

– 交流线路电压幅度和相序电路板标识

印刷线路板由印在其上的字母数字部件号来标识。例如，电源板标有部件号：

DS200DCFBG#ruu

DS200DCFB 部分是标识印刷线路板（在本例中为电源板）的基本编号。r 和 u 数字是表示电路板修订级别的字母字符。r 数字反映了不向下兼容的功能变化。它本质上是一个新的目录号。u 数字代表向下兼容的修订级别。

G# 标识一个组，它是特定板的变体。

The DS200DCFBG1BLC DCFB board provides control level power to the DC driver or exciter and provides 115 V AC, which is typically used to power the chassis cooling fan. DCFB includes the following circuits:

Control level power supply (+5, ±15 and ± 24 V dc)

Motor or generator excitation power supply circuit (except SCR module)

Armature SCR gate pulse generator driver

Circuits for measuring AC lines and DC motor or generator signals for a wide range of instruments, including:

- Armature current and voltage

- Excitation current

- AC line current

- AC line voltage amplitude and phase sequence circuit board identifier

The printed circuit board is identified by an alphanumeric part number printed on it. For example, a power supply board is labeled with a part number:

DS200DCFBG#ruu

The DS200DCFB part is the basic number that identifies the printed circuit board (in this case, the power board). The r and u numbers are alphabetic characters that indicate the revision level of the board. The r number reflects functional changes that are not backward compatible. It's essentially a new directory number. The u number represents the revision level of backward compatibility.

G# identifies a group that is a variant of a particular board.
