GE DS200UPSAG1AFD Power Supply Interface – Mark V Turbine Control Series
Imagine a gas turbine or steam turbine control system losing its power supply interface mid-operation. Within seconds, the Mark V controller loses regulated voltage distribution to its I/O boards, processor cards, and communication modules. The result: an uncontrolled turbine trip, emergency shutdown, and potentially days of costly downtime — not to mention the safety risks to personnel and equipment. The DS200UPSAG1AFD is the critical link that prevents this scenario. It is not a peripheral component; it is the power backbone of the entire Mark V control architecture.
Within the GE Mark V turbine control family, the DS200UPSAG1AFD occupies a foundational role as the dedicated Power Supply Interface Board. The Mark V system — deployed across thousands of gas turbines, steam turbines, and combined-cycle power plants worldwide — depends on this board to condition, distribute, and monitor DC power rails to all downstream control cards. Its AFD revision designation reflects field-proven engineering refinements that have made it one of the most widely specified power interface boards in global turbine OEM and aftermarket supply chains.

System Integration & Compatible Parts
The DS200UPSAG1AFD is designed to integrate seamlessly within the GE Mark V control panel ecosystem. Commonly paired components include:
- DS200TCQAG1BHF — Mark V Turbine Control Quad Board
- DS200TCDAG1AHD — Mark V Turbine Control Diagnostic Board
- DS200SDCIG2AGB — Mark V Speed/Dynamics Control Interface
- DS200SSBAG1BAA — Mark V Turbine Control Board
- DS200IIBDG1BGF — Mark V I/O Interface Board
When sourcing replacement parts, we recommend verifying the full panel BOM (Bill of Materials) to ensure revision compatibility across all installed boards.
Our Quality Assurance Process
At Konmask.com, every DS200UPSAG1AFD unit passes through a structured verification process before shipment:
- Step 1 — Source Verification: Units are sourced exclusively from authorized OEM channels, certified distributors, or decommissioned plant inventories with documented provenance.
- Step 2 — Visual & Physical Inspection: Each board is inspected for component integrity, PCB condition, connector pin alignment, and absence of corrosion or heat damage.
- Step 3 — Functional Testing: Where applicable, boards undergo bench testing against GE Mark V electrical specifications to verify power rail output and signal integrity.
- Step 4 — Documentation & Packaging: Units are shipped with inspection records, anti-static packaging, and a Konmask.com quality certificate. Traceability documentation is available on request.

Frequently Asked Questions
Q: Is the DS200UPSAG1AFD still in production by GE?
A: The Mark V series has been superseded by the Mark VIe platform. However, DS200UPSAG1AFD units remain available through authorized aftermarket channels. Konmask.com maintains stock and sourcing relationships to support legacy Mark V installations.
Q: Can the DS200UPSAG1AFD be used as a direct replacement for earlier AFx revisions?
A: In most cases, yes — the AFD revision is backward-compatible with earlier AFx revisions within the same panel configuration. We recommend confirming your panel’s BOM revision before ordering. Our technical team can assist with compatibility verification.
Q: Do you provide a warranty on this part?
A: Yes. All units sold by Konmask.com carry a standard 12-month warranty against manufacturing defects and functional failure under normal operating conditions. Extended warranty options are available for volume orders.
Q: Can you supply multiple units for a plant-wide spare parts program?
A: Absolutely. We regularly fulfill bulk orders for power plant operators and EPC contractors building critical spare inventories. Contact us for volume pricing and framework agreement options.
Q: What shipping options are available for international orders?
A: We ship globally via DHL Express, FedEx International Priority, and UPS Worldwide Express. Full export documentation is provided. We have experience shipping to the Middle East, Southeast Asia, Europe, and the Americas.
