Description

The DS200TCPSG1A is a critical power distribution component engineered for the General Electric Mark V Turbine Control System. It functions as the primary power source for the control core, converting source voltage into regulated DC rails required by the system's microprocessors and I/O modules. Deployed extensively in gas and steam turbine operations within power plants and refineries, this board is fundamental to maintaining system integrity. Its high-reliability design supports redundant controller configurations, ensuring that power remains consistent even during individual component failures, thereby eliminating single points of failure and significantly reducing costly unscheduled downtime.

Features

  • Redundant Operation: Features specialized circuitry to support parallel power sourcing, allowing multiple power supply units to load-share across the control backplane in TMR configurations.
  • Voltage Regulation: Incorporates high-grade electrolytic capacitors and voltage regulators to filter industrial electrical noise, providing clean power to sensitive digital logic circuits.
  • Diagnostic Monitoring: Integrated test points and LED indicators allow field engineers to verify rail health (such as +5 VDC, +/-15 VDC, and +24 VDC) without disrupting system operation.
  • Form Factor: Utilizes a standardized GE frame size for direct installation into the control cabinet's power supply rack, featuring high-retention connectors for vibration resistance.

Applications

This power supply board is designed for use in GE Mark V turbine control systems, specifically within power generation facilities, heavy industrial plants, and refinery operations requiring high-availability control architectures.
