Specifications

Description

DS200SDCIG2AFB is a DC Power Supply Board developed by GE. It is a part of Drive Control system. The board provides essential circuitry to instrument DC motor signals and AC lines. Specifically designed for use with external exciters, this board accommodates input voltages of up to 60o VAC, making it versatile and adaptable to a range of power systems. The board's primary function is to deliver logic power functions and interface circuitry, contributing to the overall control and operation of the DC2000 drives.

Applications

Power Supply: Provides logic power to the drive control components and can handle input voltages up to 600 VAC.

SCR Gate Driver: Built-in drive circuitry specifically designed to control the gating of the armature thyristor (SCR), thereby precisely regulating DC motor operation.

Excitation System Interface: Designed to work with an external exciter, providing necessary instrumentation and interface circuitry.

Protection Mechanism: Onboard "delayed trigger power supply circuitry" ensures power is cut off before specific triggering operations are required, preventing false triggering; in case of a fault, it automatically cuts off the gate trigger power supply to protect the hardware.

Features

1.Within the board, a multitude of circuits are integrated to facilitate various functions. These circuits include, but are not limited to, driver circuits designed for armature Silicon Controller Rectifier (SCR) gating. Additionally, motor field power circuits are provided, excluding use with an SCR module. For applications requiring external circuits, the G2 group variation of the board is equipped with the necessary features

2.When removing the board, a crucial step is to meticulously disconnect all cables before initiating the removal process. This ensures a smooth transition and minimizes the risk of damage to connectors or other components. In the event of replacement with another board, it is imperative to reconnect all cables exactly as they were on the original, maintaining the correct configuration for seamless integration

3.The driver circuits are specifically tailored for armature SCR gating, playing a pivotal role in controlling and regulating the DC motor operation. These circuits contribute to the precision and efficiency of the armature SCR gating process

4.Users should exercise caution with the user-configurable jumpers on the board, as they are susceptible to damage. In the event of damage, prompt repairs are necessary to ensure that the board continues to operate seamlessly within the Mark V system without inhibiting its true functionality

Frequently Asked Questions

Q: What is DS200SDCIG2AFB?

A: It is a DC Power Supply Board developed by General Electric under the Drive Control series.

Q: What is the purpose of the delayed firing power circuit on the DS200SDCIG2AFB?

A: The delayed firing power circuit provides power to the SCR (Silicon Controlled Rectifier) bridge gate-pulse transformer outputs with a built-in delay, ensuring power remains off until the specific gating operation is required.

Q: How does the delayed firing power circuit contribute to protection mechanisms of DS200SDCIG2AFB?

A: The circuit acts as a protective feature by withholding power until the precise moment when gating is necessary. This controlled activation minimizes the risk of undesired or premature power supply to the SCR bridge gate-pulse transformer outputs.

Q: What additional protection does the circuit offer in case of a failure of DS200SDCIG2AFB?

A: The delayed firing power circuit includes a mechanism to remove gate firing power in the event of a failure. This safety measure prevents potential damage and helps maintain the integrity of the SCR bridge gate-pulse transformer outputs.
