Description

GE DS2020PDMAG3: Power Distribution Module for Mark V Turbine Control Systems

Product Overview

The GE DS2020PDMAG3 is a power distribution module designed for GE’s Speedtronic Mark V gas turbine control system. Engineered to deliver reliable power management in industrial environments, this module supports dual voltage inputs (125V DC and 115/230V AC) and integrates with the EX2000 PWM digital regulator subsystem for brushless generator excitation systems 9. Its modular design ensures efficient power distribution to control and I/O boards, while diagnostic capabilities enable real-time monitoring of system health. Built for rugged industrial use, the DS2020PDMAG3 features conformal coating and robust connectors to withstand extreme temperatures (-20°C to +60°C) and vibration, making it suitable for power plants, oil & gas facilities, and marine propulsion systems.

Key Features and Advantages

Dual Voltage Support: The DS2020PDMAG3 accepts both 125V DC (for control logic) and 115/230V AC (for auxiliary systems), ensuring flexibility in power sourcing for Mark V installations 3. This dual-input design minimizes downtime by allowing seamless switching between power sources during maintenance.

 

Diagnostic Integration: The module collects real-time diagnostic data via its J301 connector, transmitting status updates to the VCMI (VME Chassis Management Interface) in Rack “R” 3. This enables proactive fault detection, such as overvoltage or open-circuit conditions, reducing mean time to repair (MTTR).

 

Rugged Construction: Conformal coating and corrosion-resistant components protect against moisture, dust, and chemical exposure, making the DS2020PDMAG3 suitable for offshore platforms, refineries, and high-humidity environments. Its vibration resistance (5 g, 10–2000 Hz) ensures reliability in high-stress applications like marine turbines 9.

 

Modular Design: The module’s flange-mounted structure simplifies installation within Mark V racks, while field-replaceable fuses and circuit breakers streamline maintenance. Hot-swap capability allows live replacement without system shutdown, critical for continuous-operation environments 3.

Applications

The GE DS2020PDMAG3 excels in industrial scenarios requiring robust power distribution:

 

  • Power Generation: Providing 125V DC power to turbine control logic and 115/230V AC power to auxiliary systems in gas/steam power plants.
  • Oil & Gas: Managing power for distributed control systems (DCS) in offshore platforms, refineries, and pipeline compressor stations.
  • Marine Propulsion: Ensuring stable power supply to propulsion system controls, enabling real-time adjustments to turbine speed and fuel injection.
  • Industrial Manufacturing: Powering turbine-driven machinery in chemical plants and steel mills, minimizing production interruptions.
  • Renewable Energy: Supporting hybrid power systems by distributing power to control modules in combined heat and power (CHP) plants.

Compatibility and Related Products

  • Mark V Compatibility: The DS2020PDMAG3 is exclusively designed for GE’s Mark V turbine control system and not compatible with Mark VIe components like the DS2020PDMAG4 11.
  • EX2000 Subsystem: Integrates with the EX2000 PWM digital regulator for brushless generator excitation, ensuring stable voltage control in power generation applications 9.
  • Ancillary Modules:
    1. GE DS200TBQBG1ACB Terminal Board: Provides signal conditioning for analog inputs/outputs connected to the DS2020PDMAG3.
    2. GE DS2020UCSAG1A Control Processor: Central CPU for Mark V systems, reliant on the DS2020PDMAG3 for power.
    3. GE DS2020UCOCNIG1A Communication Module: Interfaces with external devices, requiring power from the DS2020PDMAG3.

Installation and Maintenance

Installation Steps:

 

  1. Power Off: Ensure the Mark V rack is de-energized and grounded.
  2. Mounting: Secure the DS2020PDMAG3 using flange screws, aligning it with the rack slot.
  3. Wiring: Connect 125V DC and 115/230V AC inputs, verifying polarity. Attach the J301 diagnostic cable to the VCMI.
  4. Configuration: Set JTX1/JTX2 jumpers for 115V or 230V AC input as needed 3.

 

Maintenance Recommendations:

 

  • Daily: Check LED indicators for power status and fault conditions.
  • Monthly: Inspect connectors for corrosion or looseness, particularly in high-vibration environments.
  • Annually: Test overcurrent protection by simulating a fault condition and verifying fuse operation.
  • Firmware Updates: Apply GE-released firmware via the Mark V programming interface to access bug fixes.
  • Spare Parts: Stock replacement fuses (3A fast-blow) and circuit breakers for rapid repairs.

Availability and Support

  • New Units: Available through GE authorized distributors with a 1-year warranty.
  • Refurbished Units: Third-party suppliers like AX Control and World of Controls offer certified refurbished units with extended warranties (e.g., 3-year coverage) 39. Repair services typically take 3–7 days.
  • Technical Support: GE’s global network provides 24/7 assistance for troubleshooting and system integration.

Product Assurance

The DS2020PDMAG3 is backed by GE’s 1-year warranty for defects in materials and workmanship. Refurbished units undergo rigorous testing to meet OEM standards, ensuring reliability for cost-sensitive projects. With its dual voltage support and diagnostic capabilities, the module delivers long-term value in mission-critical industrial applications.
