Description
- The WOODWARD 5453-278 is a high-reliability power supply module specifically engineered for the MicroNet control system architecture. This module provides the stable, regulated DC power required for the system’s central processing units and I/O modules to function correctly. Designed for continuous duty in harsh industrial environments, the 5453-278 features advanced protection against input surges and thermal overloads, ensuring that critical turbine and engine control operations remain uninterrupted even during electrical fluctuations.
Technical Specifications (Datasheet)
Model Number: 5453-278 Manufacturer: Woodward Module Class: Power Supply / Power Distribution System Compatibility: MicroNet Simplex and TMR Systems Input Voltage Range: 18-36 VDC (Low Voltage Version) Output Voltage: Regulated DC for Backplane Support Dimensions: 20.3 cm x 15.2 cm x 7.6 cm Weight: 1.45 kg Country of Origin: USA
Application Fields
This power module is essential for maintaining the operational uptime of Woodward-based control racks in:
- Utility Power Generation: Ensuring the main controller for gas or steam turbines has consistent power.
- Petrochemical Refineries: Powering critical automation for compressor and pump control systems.
- Marine Engineering: Providing regulated energy for main engine governors on large vessels.
- Offshore Platforms: Operating reliably in remote environments with variable local power quality.
Product Usage Instructions
- Chassis Slot Selection: The 5453-278 must be installed in the dedicated power supply slots of the MicroNet chassis (typically the leftmost slots).
- Input Power Connection: Connect the 24VDC source to the input terminals. Ensure that the wire gauge is sufficient to handle the module’s peak current draw without significant voltage drop.
- Redundancy Setup: In TMR (Triple Modular Redundant) systems, ensure multiple power modules are installed to allow for failover capability. The modules are designed to share the load across the backplane.
- Heat Dissipation: Ensure the rack cooling fans are functional and the airflow vents on the module faceplate are not obstructed to prevent thermal shutdown.
- Status Monitoring: Upon powering up, check the “Power OK” LED. If the LED is off or red, check the input fuse and the backplane connection immediately.
Frequently Asked Questions (Q&A)
Q: Can this power supply be used with 110VAC or 220VAC inputs? A: No, the 5453-278 is a DC-to-DC power supply designed for 18-36 VDC inputs. For AC applications, a separate Woodward AC/DC converter module is required.
Q: Is the 5453-278 hot-swappable in a redundant system? A: Yes, in a redundant MicroNet configuration, a faulty power module can be replaced while the system is running, provided at least one other power module is healthy and carrying the load.
Q: What is the indicator for an internal fault? A: An internal failure is typically indicated by a “Fault” LED on the front panel or a loss of the “Power OK” signal to the system CPU.
Q: Where can I find pricing and lead times for this component? A: For official quotes and technical support regarding the WOODWARD 5453-278, please visit https://www.newplcdcs.com for assistance with your industrial spare parts needs.
