Woodward 5501-380 MicroNet TMR Power Supply 120 VAC/VDC Input

Woodward 5501-380 MicroNet TMR Power Supply 120 VAC/VDC Input

Functional Description

5501-380 is a TMR Power Supply developed by Woodward. The TMR main control power supply chassis is engineered for optimal reliability and fault tolerance through the implementation of redundant power supplies. This design ensures uninterrupted power delivery to critical control components, enhancing the overall robustness of the system. At the heart of this redundant power system lies a specialized motherboard, strategically positioned on the back of the power supply chassis. This motherboard plays a pivotal role in coordinating the operation of the two power supplies, creating a seamless and efficient redundant power configuration.

Features

• The redundant power system boasts six separately regulated 24 Vdc outputs, each with an impressive current capacity of 6 A. These outputs are meticulously designed to deliver stable and precise power to the control, ensuring the smooth functioning of all connected modules and components.
• To maintain exceptional power output regulation, the system implements stringent measures to counter the effects of line voltage fluctuations, varying load demands, and changes in temperature. As a result, the regulation is meticulously controlled and kept within an impressive margin of less than +5%.
• The implementation of redundant power supplies and the high-quality motherboard enhances the system's overall fault tolerance and reliability. In the event of a power supply failure or issue, the redundant power system ensures that the other power supply seamlessly takes over, maintaining continuous operation and safeguarding critical processes.
• The reliable power delivery and precise regulation of the MicroNet TMR main control power supply chassis make it well-suited for safety-critical applications in industries such as aerospace, nuclear power, and industrial automation. The redundant power system and robust motherboard are at the forefront of providing a stable and dependable power foundation for the MicroNet TMR control system, ensuring exceptional performance and safety even in demanding and mission-critical environments.

Characteristics

• The implementation of redundant power supplies in the MicroNet TMR main control power supply chassis goes beyond merely providing backup power. A sophisticated current sharing circuitry is integrated into the system to ensure efficient load balancing among the redundant power supplies. This balancing mechanism dynamically distributes the load across the active power supplies, reducing heat generation and optimizing power utilization. As a result, the reliability of the power supplies is significantly improved, and the risk of overheating or premature failures is minimized.
• One of the key advantages of this current sharing circuitry is its ability to facilitate hot replacement of power supplies. In the event that one power supply requires replacement due to a fault or maintenance, the current sharing mechanism smoothly transfers the load to the remaining active power supplies. This seamless transition ensures uninterrupted power delivery to the control, allowing for a hot swap of the faulty power supply without disrupting the operation of the system. This feature is of utmost importance in safety-critical applications where continuous operation is paramount.
• Each main power supply in the MicroNet TMR control system is equipped with four LEDs, serving as valuable indicators of the power supply's health and status. The first LED signifies the overall health of the power supply, indicating whether it is functioning correctly (OK). The second LED denotes any input fault, alerting users if there are issues with the input voltage or power source. The third LED is dedicated to detecting overtemperature conditions, providing an early warning if the power supply is operating at elevated temperatures that may require attention. The fourth LED serves as an indicator of any power supply fault, helping users quickly identify potential issues or failures within the power supply.
• The combination of redundant power supplies, current sharing circuitry, and LED indicators in the MicroNet TMR® main control power supply chassis showcases Woodward's commitment to providing a highly reliable and fault-tolerant power solution. This comprehensive approach ensures continuous and stable power supply, enabling the MicroNet TMR control system to excel in safety-critical applications and deliver unmatched performance and safety in demanding industrial environments.
