Compatible Replacement & Equivalent Models
When the DS200UPSAG1AFD is discontinued, obsolete, or on extended lead time, the following models may serve as functional replacements depending on your rack configuration and firmware revision. Always verify compatibility with your system integrator before substitution.
- DS200UPSAG1AFA — Earlier revision; functionally equivalent in most Mark VI racks
- DS200UPSAG1AFB — Intermediate revision; check firmware compatibility
- DS200UPSAG1AFC — Predecessor to AFD; same pinout and power ratings
- IS200UPSAG1A — Mark VIe platform equivalent (confirm rack compatibility)
- DS200DCFBG1A — DC power filter board used in conjunction with UPS modules
- Third-party equivalents: Contact Konmask for cross-reference to approved aftermarket alternatives
Note: Revision suffix (AFD vs. AFC, etc.) may affect firmware handshake. Consult GE GEH-6421 documentation or contact our technical team for confirmation.
Why Choose the Original DS200UPSAG1AFD
- OEM Firmware Compatibility: Guaranteed handshake with Mark VI VCMI, VTUR, and VPRO boards without re-parameterization

- Regulatory Compliance: Meets GE Mark VI system-level safety and EMC certifications
- Reduced Commissioning Risk: Drop-in replacement with no rack modification required
- Long Service Life: Engineered for 10+ year operational lifespan in industrial environments
Typical Applications
- Gas turbine control panels (Frame 5, Frame 6, Frame 7, Frame 9 series)
- Steam turbine and combined-cycle power plant control systems
- Compressor station automation using GE Mark VI controllers
- Offshore platform turbine control upgrades and retrofits
- Spare parts inventory for power utility maintenance programs
System Compatibility
- Primary Platform: GE Mark VI Turbine Control System
- Rack Type: Mark VI VME-based I/O rack (R, S, T racks)
- Compatible Controllers: VCMI, VTUR, VPRO, VSVO boards
- Not Compatible With: Mark V (DS200 series with different backplane), Mark VIe (IS200 series — different form factor)
- Software: Works with GE Toolbox (ToolboxST) for Mark VI configuration
Selection Guide
Use the following criteria to confirm DS200UPSAG1AFD is the correct module for your application:
- ✅ Your control system is GE Mark VI (not Mark V or Mark VIe)
- ✅ Your rack uses VME backplane with standard Mark VI power bus
- ✅ You require 28 VDC regulated output to I/O boards
- ✅ Input supply is 120 or 240 VAC single-phase
- ✅ Slot position matches UPS module slot in your rack layout drawing
If any of the above do not match, contact our engineering team with your rack serial number and GE project number for a precise cross-reference.

Replacement & Compatibility FAQ
Q: Can DS200UPSAG1AFC replace DS200UPSAG1AFD directly?
A: In most cases yes, as the hardware is functionally identical. However, firmware revision differences may require a ToolboxST parameter check. We recommend testing on a non-critical rack first.
Q: Is DS200UPSAG1AFD compatible with Mark VIe systems?
A: No. Mark VIe uses the IS200 series with a different form factor and backplane. The correct equivalent for Mark VIe is IS200UPSAG1A.
Q: What is the difference between DS200UPSAG1AFD and DS200UPSAG1AFA?
A: The suffix letter indicates hardware revision. AFD is the latest known revision with minor component updates for improved MTBF. Functionally interchangeable in standard Mark VI racks.
Q: Do you offer exchange / core return programs?
A: Yes. Contact us for our exchange pricing — send your failed unit and receive a tested replacement at reduced cost.
Q: Can I get a datasheet or GE documentation?
A: Yes. Request GEH-6421 or the Mark VI I/O Module Reference via our support email.
