The 5501-429 (Model: 5501-429) is a high-integrity power supply module engineered specifically for the Woodward MicroNet™ TMR (Triple Modular Redundant) digital control system. This module is the backbone of mission-critical turbine and engine control, providing regulated DC power to the control chassis while maintaining strict fault tolerance. The 5501-429 (Part Number: 5501-429) is designed to prevent single-point failures in the power distribution layer, ensuring that gas turbines, steam turbines, and large compressors remain operational even during localized power disturbances.
Operating at a nominal 220 VAC, the 5501-429 (Power Module: 5501-429) integrates advanced diagnostics with front-panel LED indicators for real-time monitoring of input health, thermal state, and logic status. Its hot-swappable architecture allows maintenance personnel to replace a module without de-energizing the system, effectively eliminating downtime during power unit servicing. Built with industrial-grade surge suppression and a dedicated circuit breaker, it is optimized for the harsh electrical environments of power generation plants and oil & gas facilities.
The 5501-429 (5501-429) combines high power density with specialized protection mechanisms required for TMR chassis integrity.
