Overview

The Woodward 5501-380 is a rugged, high-performance power supply module engineered for use in MicroNet Triple Modular Redundant (TMR) control systems. It provides regulated 24 VDC output from a 120 VAC or 120 VDC input, ensuring stable power delivery to control and I/O modules in mission-critical applications.

This module supports six independent 24 VDC outputs, offering redundancy and load-sharing capabilities. Moreover, it features front-panel LED indicators for real-time diagnostics and system status monitoring. With an efficiency rating of 94% and tight regulation accuracy of ±1%, the 5501-380 ensures minimal power loss and consistent performance under varying load conditions.

Therefore, it is widely used in power generation, oil & gas, marine, and industrial automation sectors where uninterrupted control system operation is essential.
