The Woodward 5466-1049 is a critical Triple Modular Redundant (TMR) power supply module. It operates within the Woodward MicroNet Digital Control system architecture. This module provides a main power supply of 24 VDC for system components. It then precisely regulates this input to a stable 5 VDC output for the protected kernel section.
Core Technical Specifications and Compatibility
Engineers must ensure specific compatibility when integrating this power module. The Woodward 5466-1049 is designed exclusively to work with the TMR5200 central processing unit. For safety and system integrity, follow strict replacement procedures during maintenance. All kernels within the MicroNet TMR Kernel Power Supply must be removed prior to any module installation or removal.
