Description

The General Electric IS2020RKPSG1AK is a high-performance VME rack power supply module engineered for the Mark VI and Mark VIe Speedtronic turbine control systems. This module serves as a critical power distribution component, converting 125 VDC input power into multiple regulated DC output voltages required for backplane operation, control logic, and specialized instrumentation such as flame detectors.

Features

• Self-contained VME rack power supply design.
• 400W total output capacity.
• Supports 125 VDC input voltage.
• Nine distinct output channels, including dedicated +28V remote outputs.
• Integrated diagnostic LED indicators (Green, Red, Yellow) for real-time status monitoring.
• Front-panel toggle switch for manual fault reset.
• Waffled faceplate design to facilitate airflow and thermal management.

Applications

• Gas and Steam Turbine Control: Provides reliable power for startup, speed regulation, fuel control, and generator synchronization.
• Wind Turbine Management: Supports pitch control and grid integration within the Mark VI series architecture.
• Flame Detection Systems: Delivers specialized 335 VDC output for TRPG flame sensors.
• Heavy Industrial Control: Suitable for DCS and SCADA environments requiring robust, rack-mounted power solutions.

Technical Specifications

Installation Guidelines

• Ensure the VME rack is powered down before inserting or removing the module to prevent electrical arcing or damage to the backplane.
• Verify the input voltage matches the 125 VDC specification before connecting to the bottom input terminal.
• The module relies on proper rack mounting to ensure the integrated fan effectively manages internal temperatures; do not obstruct the waffled faceplate.
• Establish separate wiring paths for standard +28 VDC outputs and the high-voltage 335 VDC flame detector output to minimize interference.
• Connect the Status ID cable to the bottom connector to enable real-time diagnostic reporting to the controller.

FAQ

What is the primary function of the IS2020RKPSG1AK?

This module functions as a dedicated VME rack power supply, providing regulated voltage and current to components within the GE Speedtronic control rack.

What do the LED indicators signify?

The unit features Green, Yellow, and Red LEDs. Green indicates normal operation, while Red and Yellow signals are used to identify specific fault conditions that may require a reset via the front-panel toggle switch.

What outputs does this module provide?

The module distributes various DC voltages, typically including +5V, +/-12V, +/-15V, and +28V to the VME backplane, with an additional 335 VDC output available for flame detection systems.
