Functional Description
IS200RKPSG2A is a VME rack power supply developed by GE. It is a part of Mark VI series. The Mark VI VME rack power supply is an essential component located alongside the VME control and interface racks. Its primary function is to provide diverse direct current (dc) voltages to the VME backplane, including 5V, 12V, 15V, and 8V. Additionally, it offers an optional 335V dc output specifically for powering flame detectors connected to the TRPG.
Features
- Voltage Output and Options: The power supply unit delivers these multiple dc voltages to the VME backplane, catering to various operational requirements. Specifically designed for powering flame detectors connected to the TRPG, providing a dedicated power supply for this critical system component.
- Input Voltage Flexibility: Two Supply Input Voltage Selections: The power supply offers two distinct input voltage options- 125V DC Input Supply, Powered by a Power Distribution Module (PDM), offering higher voltage input. Low Voltage Version for 24V DC Operation, Provides compatibility and operation at a lower voltage level.
- Stand-Alone Control Rack: Different Power Supply for Stand-Alone Control Rack exclusively powers the Mark VI controller, VDSK, and VCMI, providing dedicated support for these specific components. The RKPSG2 and LVPSG2 have been introduced as direct replacements for the RKPSG1 and LVPSG1, respectively. Enhancements in Newer Designs: While maintaining compatibility, these updated power supply units offer improved features and functionalities compared to their predecessors. The introduction of the RKPSG2 and LVPSG2 represents a modernization effort to enhance the capabilities and reliability of the power supply units within the Mark VI system, ensuring more efficient and robust performance for the VME rack and associated components.
LED indicators
- The Yellow LED plays a role in indicating the status of the input power when the power switch is OFF. If this LED is ON, it signifies that there is power present on the supply input connector. In newer designs, the functionality of the Yellow LED is enhanced to improve accuracy. Specifically, the Yellow LED will only turn ON if the input voltage is above the input under-voltage fault threshold. This added feature ensures that the LED does not indicate the presence of power unless the voltage is sufficient, thereby providing a more reliable indication of the actual power status.
- Red LEDThe Red LED is designed to indicate the detection of a fault within the system. This LED will only be illuminated if there is input power, the power switch is ON, and a fault has been detected. The presence of the Red LED serves as a critical warning signal, alerting users to investigate and address any issues promptly to avoid potential system failures or malfunctions. Its functionality is essential for maintaining the integrity and reliability of the exciter system.
- The Green LED signifies normal operational status and provides assurance that the board is functioning correctly. It will be ON if there is input power, the power switch is ON, and no detectable faults are present. This LED is a clear indicator that the system is operating smoothly without any issues. In addition to the visual indication provided by the Green LED, newer designs of the EACF board include a status output feature that mimics the status of this LED. The status output is a Normally Open (NO) solid-state relay contact that will be CLOSED when the Green LED is ON. This relay contact can be used to provide a remote indication of the board’s status, facilitating integration with other monitoring and control systems. This feature allows for enhanced monitoring capabilities and ensures that the operational status of the board can be easily tracked from a remote location.
Installation
Mounting Location and Connections:
- Mounting: The power supply is positioned on the right-hand side of the VME rack, secured by a sheet metal bracket for stability.
- Connection Points: The dc input, 28V dc output, and 335V dc output connections are located at the bottom of the power supply. Additionally, the newer design incorporates a status connector also positioned at the bottom.
- Top Connectors PSA and PSB: These connectors, situated at the top of the assembly, correspondingly connect with a cable harness responsible for transmitting power to the VME rack.
28V DC Power Modules and Rack Sections:
- Power Distribution: Five individual 28V dc power modules supply different sections of the VME rack, each designated as A, B, C, D, E, and F.
- Peripheral Device Power: The P28C output or PS28 located at the bottom of the power supply can be utilized to power an external peripheral device. To enable this function, the jumper plug displayed on the bracket to the left of the rack must be relocated from the Normal position to the Isolated position below.
Fan Operation and Controller Placement:
- Fan Utilization: The fan operates exclusively when the controller is mounted within the rack, facilitating cooling and ensuring optimal functioning. Its power is sourced from the top connector on the same bracket, located specifically on the left side of the rack.
- The installation process ensures proper positioning of the power supply within the VME rack, establishing essential connections for input, output, and peripheral device support.
- Additionally, it incorporates measures to activate the fan for temperature regulation, particularly when the controller is installed, maintaining an optimal operating environment within the rack setup.

Frequently Asked Questions
What is IS200RKPSG2A?
It is a VME rack power supply developed by GE under the Mark VI series.
If the red LED on the power supply is ON, does it mean the power supply needs replacement?
Not necessarily. The red LED being ON doesn't always indicate a power supply failure. It could signal a system fault, causing the LED to latch on. Check the system for issues before considering power supply replacement.
Why might the red LED be illuminated?
The red LED being ON suggests a potential problem within the system rather than an immediate power supply failure. It's a signal to investigate the system for underlying issues triggering the fault LED.
What should be done if the red LED is ON?
When the red LED is illuminated, conduct a system check to identify and resolve any issues causing the fault LED to latch on. Don't rush into replacing the power supply, instead, diagnose the system for the root cause of the LED indication.
