GE DS200DCFBG1BKC – Power Distribution/Power Supply Board for Mark V Cabinets

The GE DS200DCFBG1BKC is a Mark V “power panel” board that distributes and conditions cabinet power for the control core and peripheral modules. From my experience, this board typically sits in the power section of the Mark V and provides the regulated rails and protected outputs the system relies on for steady operation. If you’re maintaining a gas/steam turbine control cabinet, this is one of those hardware pieces that keeps the rest of the rack calm and predictable.

Key Features

• Power distribution for Mark V – Routes cabinet AC/DC feeds to the control core and I/O, with onboard protection to minimize nuisance trips.
• Regulated low-voltage rails – Provides the stable control voltages that Mark V logic boards depend on, which typically improves noise immunity.
• Fusing and status indications – You might notice convenient test points and fuse protection that speeds up troubleshooting during outages.
• Backplane connectivity – Direct plug-in/backplane connectors reduce wiring complexity and improve serviceability.
• Form-fit for DS200 platform – Fits standard Mark V racks, making swaps straightforward during planned maintenance windows.
• Field-proven reliability – In many cases, this board has outlasted surrounding components; it’s a common spare in turbine maintenance kits.

Technical Specifications

Application Fields

This board is commonly used in:

• Gas and steam turbine control cabinets (Mark V)
• Power generation plants needing stable control power distribution
• Oil & gas compressor stations and mechanical drive packages
• Industrial facilities running legacy GE Mark V-based process control

One thing I appreciate is how it stabilizes cabinet rails during line disturbances. A maintenance lead told us, “Swapping in a verified DS200DCFBG1BKC got our rack voltages back within spec, and nuisance trips disappeared the same shift.”

Advantages & Value

• Reliability – Proven in harsh plant conditions; typically provides better uptime versus ad‑hoc power fixes.
• Compatibility – Form-fit-function for Mark V, minimizing retrofit work and downtime.
• Lifecycle support – Supports a large installed base; spares strategy is straightforward.
• Cost control – Targeted replacement of the power panel often avoids wider rack overhauls.
• Technical backing – We can assist with part identification, revision matching, and rack-level checks.

Installation & Maintenance

• Environment – Install in a clean, ventilated control cabinet. Maintain airflow; avoid dust and conductive debris.
• Safety – De-energize cabinet AC/DC feeds before handling. Observe ESD precautions; handle by edges only.
• Wiring – Verify terminal labeling and fusing. Tighten terminals to torque spec; inspect backplane connectors for bent pins.
• Commissioning – After installation, check cabinet rails (e.g., low-voltage outputs) are within expected tolerance before enabling control.
• Routine checks – Inspect fuses, connectors, and any electrolytic capacitors during outages. Clean light dust with dry, oil-free air.
• Firmware – No user firmware on this board; parameters are managed by the controller (Mark V core).

Quality & Certifications

• Industrial component for incorporation in CE/UL compliant systems (system-level compliance in most cases)
• Manufactured to OEM quality standards; RoHS status may vary by vintage/revision
• Supply chain managed under ISO 9001 practices
• Warranty: 365 days coverage

Related and Supporting Components

The DS200DCFBG1BKC is often seen alongside common Mark V boards such as DS200LDCCH1A (control core), TCQA/TCQC I/O boards, and relay/terminal modules.
