GE DS200PCCAG6A

Overview

The GE DS200PCCAG6A is a Power Connect Board (PCCA) designed for GE Mark V drive and turbine control applications. It is also associated with GE EX2000 and related excitation/drive equipment. The board provides an interface between control circuitry and the SCR power bridge, making it an important component in systems that require controlled power conversion and gate-drive signaling.

The DS200PCCAG6A belongs to the DS200 family of GE Mark V printed circuit boards. Its Group 6 configuration is designed for higher-power applications and is compatible with J, K, and M frame arrangements.

The board's exact system ratings and configuration should always be checked against the equipment documentation before replacement.

Key Functions

The primary purpose of the DS200PCCAG6A is to provide the electrical interface between the drive control circuitry and the SCR power bridge. Pulse transformers on the board are used for SCR gate-drive functions. This arrangement provides electrical isolation between the control side and the power switching section.

The board can also work with the GE DCFB power supply board. Its Group 6 design uses six transformers arranged in a single row, while other transformer positions may remain unpopulated depending on the board configuration.

Hardware Design

The DS200PCCAG6A is constructed as a dedicated industrial PCB assembly with transformers, plug connectors, power-interface circuitry, and associated protection components. The G6 version has a different configuration from several earlier PCCA variants. In particular, the available technical documentation indicates that this version does not use the jumpers found on many other PCCA versions.

Typical Applications

The GE DS200PCCAG6A can be considered for:

• GE Mark V drive systems
• Turbine control equipment
• GE EX2000 excitation systems
• Industrial power conversion equipment
• SCR bridge control applications
• Legacy automation system maintenance

Installation and Maintenance

Because the PCCA board can be exposed to hazardous electrical voltages during operation, installation should only be performed by qualified personnel. Before accessing the board, completely de-energize the associated equipment and verify that stored electrical energy has been discharged.

When replacing the board, technicians should compare the complete part number and revision, inspect all connectors, and confirm that the replacement matches the original system configuration. The board is generally treated as a complete replacement assembly rather than a field-repairable collection of individual components.

Why Keep a Spare?

The DS200PCCAG6A is used in legacy GE control equipment where finding an exact replacement can become increasingly difficult as systems age. Maintaining a compatible spare can therefore reduce equipment downtime and simplify corrective maintenance.

Our company supplies GE DS200PCCAG6A Power Connect Boards for industrial automation maintenance, replacement, and spare-parts requirements.
