Functional Description
IS2020LVPSG1AC is a Power Supply Module developed by GE. It is a part of the Mark VI control system. The power supply unit is conveniently mounted on the side of the VME racks, ensuring easy accessibility and integration within the system setup. It is designed to accommodate both 5, 12, 15, and 28 V dc outputs to the VME backplane, catering to diverse operational requirements.
Features
- Input Voltage Selection: The power supply unit offers flexibility in input voltage selection, providing two distinct options to suit different operational scenarios. The primary input supply is a 125 V dc configuration, sourced from a dedicated Power Distribution Module (PDM). This setup ensures robust and reliable power delivery to the VME rack components. Alternatively, for applications requiring lower voltage operation, a secondary option for 24 V dc input is available, offering compatibility with a broader range of system configurations and environments.
- Functional Outputs: With multiple output voltage options, the power supply unit delivers stable and regulated power to the VME backplane, supporting the operation of various control and interface components within the system architecture. The provision of both positive and negative voltage outputs enables comprehensive power distribution tailored to the specific requirements of individual system modules and peripherals.
- Integration with System Components: The power supply unit seamlessly integrates with other components of the VME control and interface racks, ensuring harmonious operation and efficient power management across the system. Its strategic placement on the rack side optimizes space utilization while facilitating convenient access for maintenance and servicing tasks as needed.
- Reliability and Performance: Engineered to meet stringent performance standards, the Mark VI VME rack power supply exemplifies reliability and durability in demanding industrial environments. Its robust construction and advanced circuitry ensure consistent power delivery, minimizing downtime and enhancing the overall operational efficiency of the control system.
Installation
- The power supply unit is affixed to the right-hand side of the VME rack using a sturdy sheet metal bracket. Positioned at the bottom of the unit are the inputs for DC power, along with outputs for both 28 V DC and 335 V DC. In the updated design, a status connector has been included at the bottom for improved monitoring and control. At the top of the assembly, two connectors, PSA and PSB, are situated to connect with a cable harness responsible for transmitting power to the VME rack.
- Power Distribution within the VME Rack: Each of the five 28 V DC power modules within the supply unit is allocated to power a specific section of the VME rack, which is segmented into labeled sections A, B, C, D, E, and F. Notably, the P28C output or PS28 at the base of the power supply can be utilized to power an external peripheral device if required. To enable this functionality, the jumper plug located on the bracket to the left of the rack must be repositioned from the Normal setting to the Isolated setting below it.
- Cooling System Integration: The cooling fan associated with the power supply unit operates solely when the controller is installed within the rack. Its power supply is facilitated through the top connector on the bracket, which is conveniently situated on the left side of the rack. This configuration ensures optimal airflow and temperature regulation within the rack assembly, contributing to the efficient operation and longevity of the components.
Fault Conditions
- Transient Output Shutdowns: These faults result in the temporary shutdown of one or more output channels of the power supply. While disruptive, these shutdowns are typically brief and do not necessitate manual intervention to resolve. The affected output channels may automatically resume operation once the fault condition is rectified or mitigated.
- Reset-Required Faults: In this category, faults occur that require manual intervention or a reset action to clear. Unlike transient shutdowns, these faults persist until appropriate measures are taken to reset the power supply unit. Depending on the nature of the fault, this may involve power cycling the unit, performing specific reset procedures, or addressing underlying issues causing the fault.
- Permanent Failures: These faults represent the most severe category, indicating permanent failures within the power supply unit. Such failures render the affected components or circuits inoperable and typically necessitate the replacement of the entire power supply unit. Permanent failures may result from critical component damage, circuitry malfunctions, or other irreparable issues, requiring comprehensive troubleshooting and remediation measures.
- Addressing Fault Conditions: Upon detection of any fault condition, it is imperative to follow established protocols for fault diagnosis, mitigation, and resolution. Depending on the severity of the fault and its impact on system operation, appropriate steps should be taken promptly to restore normal functionality, minimize downtime, and ensure the reliability and integrity of the power supply system. Regular maintenance, monitoring, and proactive troubleshooting can help prevent and mitigate fault conditions, ensuring the continued performance and stability of the power supply unit.
