Main Features

Reliable Power Management

The DS200UPSAG1A is designed to provide stable power for compatible control equipment. Stable power is important for continuous turbine system operation.

Therefore, the board helps support reliable performance in demanding industrial environments.

Built-In Protection

The board includes three fuses. They help protect circuits against overcurrent conditions.

It also contains multiple capacitors. These components support the board's power conversion and filtering functions.

Simple Diagnostic Design

A front-board LED provides basic operating information. In addition, the board includes a reset button.

These features can help technicians during maintenance. They also make basic troubleshooting more convenient.

Board Structure

The DS200UPSAG1A uses a compact printed circuit board design. Several functional areas work together to manage system power.

The main components include:

• Three protective fuses
• One status LED
• One reset button
• Three 9-pin connectors
• Multiple capacitors
• Power conversion circuitry
• Test and adjustment points

The board also includes a factory-set potentiometer. This component is used for voltage adjustment and should not be changed without the proper technical procedure.

Applications

The GE DS200UPSAG1A is associated with UC2000 and EX2000 systems. It can be found in industrial power and turbine applications.

Typical applications include:

• Gas turbine control systems
• Steam turbine systems
• Generator excitation systems
• UC2000 equipment
• EX2000 excitation systems
• Industrial power generation
• Legacy GE control system maintenance

Its power supply function makes it an important replacement component for compatible equipment.

Installation and Maintenance

Before installation, always verify the complete part number. Also, confirm the board is compatible with the existing system.

Power must be removed before servicing the board. The capacitors can retain electrical energy after power is disconnected. Therefore, technicians should follow proper discharge and safety procedures before handling the PCB.

For routine maintenance, check the following:

• Fuse condition
• Board connectors
• Status LED
• Capacitors
• Wiring connections
• Signs of overheating
• Physical PCB damage

Furthermore, avoid changing factory-set adjustments without the correct service documentation.

Product Value

The GE DS200UPSAG1A remains a useful spare part for legacy GE industrial systems. Its power supply function supports reliable operation of compatible UC2000 and EX2000 equipment.

For maintenance teams, keeping a suitable replacement board available can reduce equipment downtime. It can also simplify repairs when an original power supply board fails.

We supply GE DS200UPSAG1A for turbine control and industrial automation replacement projects. Our supply service supports customers looking for GE Mark V and EX2000 spare parts.
