Product Description
Product: DS200CDBAG1 – GE Mark V CDBA Base Contactor Driver Board
GE DS200CDBAG1 | Original Base Version Contactor Driver Card for Speedtronic Mark V Turbine & AC/DC2000 Drives
DS200CDBAG1 is the original base revision CDBA Contactor Driver PCB developed by General Electric for the legacy Speedtronic Mark V turbine control platform and AC2000 / DC2000 medium voltage converter cabinets. It is the foundational base model without extended suffix revision codes (BDB/A/B), while DS200CDBAG1BDB is its later upgraded assembly variant. This board serves as the dedicated drive interface between rack power supply boards (DCFB, SDCI, DCVA) and high-speed main circuit contactors, adopting two-stage coil drive logic: transient high voltage pulse for rapid contactor pull-in, followed by low steady holding voltage to reduce coil heat. When drive overcurrent, overvoltage or unit fault signals trigger, it instantly cuts coil power to realize fast main circuit isolation protection, widely matched with gas/steam turbine auxiliary heavy-duty frequency conversion systems.
Core Technical Specifications
- Base Part No.: DS200CDBAG1 | Brand: General Electric | Platform: Speedtronic Mark V
- Function Definition: CDBA Contactor Driver Board (Original Base Revision)
- Input Power Range: 75–140 VAC/DC, built-in 4A 125V slow-blow fuse FU1 for overcurrent protection
- Compatible Contactor Coil: 30–40 VDC high-speed power contactors only
- Dual-Stage Drive Output: 105VDC 250ms pull-in pulse + regulated low holding DC voltage
- Onboard Hardware: RV1 current adjustment potentiometer, JP2 multi-board synchronization jumper, run status LED, 3 dedicated test measuring terminals (REF A, +15V, common reference)
- Rack Installation: Single-slot plug-in card for standard Mark V control rack backplane
- PCB Protection: Standard conformal coating for dust, moisture and mild corrosive gas resistance
- Operating Temperature: -30°C ~ +65°C | Storage Temperature: -40°C ~ +85°C
- Anti-Interference Design: Integrated surge absorption diode and RC noise suppression circuit
- Certifications: CE, UL industrial safety & EMC anti-interference standards
- Difference from DS200CDBAG1BDB: DS200CDBAG1 is bare base PCB; BDB suffix version is complete assembled upgraded assembly with reinforced component layout
Main Functional Features
- Two-stage coil drive circuit reduces continuous power consumption, lowers contactor coil temperature and extends service life
- JP2 synchronization jumper supports parallel coordination of multiple CDBA boards to realize simultaneous closing of multi-bridge main contactors
- RV1 adjustable potentiometer calibrates output drive current to match different specification contactor coils, avoid coil burnout damage
- Front panel LED real-time display contactor closing command signal, convenient on-site visual fault judgment without testing instruments
- Instant power-off trip logic under fault state, quickly cut off main power circuit to protect power modules and turbine host equipment
- Independent test points support offline voltage measurement without full disassembly for daily maintenance troubleshooting
- Built-in multi-layer hardware protection: reverse polarity, short-circuit and transient overvoltage suppression circuit
- Standard plug-in modular structure, easy disassembly and spare part replacement during power plant unit overhaul
