Product Overview

The 5466-318 (Part Number: 5466-318) is a high-performance Kernel Power Supply (KPS) module specifically engineered for the Woodward MicroNet™ Triple Modular Redundant (TMR) control system. As a Rev B iteration, this module provides critical 5 VDC regulated power to the TMR040 CPU and the internal communication bus. Its architecture is built for environments where downtime equates to significant operational loss, utilizing fault-tolerant pathways to ensure continuous logic processing even during a single-path power failure.
