Woodward 5453-277 110-380V AC/DC TMR Power Supply Frame

Product Description

Triple Modular Redundant Power Architecture

The Woodward 5453-277 is a high-availability Triple Modular Redundant (TMR) Power Supply Chassis designed specifically for the MicroNet TMR control platform. This chassis acts as the electrical backbone for mission-critical control systems, ensuring that power is distributed seamlessly to vital processing and I/O modules. By utilizing a TMR architecture, the 5453-277 houses three independent power paths; if a single power supply module fails, the remaining units automatically share the load without any dip in output voltage or interruption to the controller's logic execution.

Engineering for Uninterrupted System Operation

Designed for the most demanding industrial environments, the 5453-277 supports a broad universal input range of 110–380 V AC/DC, providing localized regulation and isolation. The chassis is engineered with advanced load-sharing circuitry that balances current draw across all installed power modules to extend hardware lifespan. It features a rugged mechanical frame compatible with standard MicroNet rack configurations, facilitating easy integration into existing turbine and engine control cabinets. The internal bus structure is optimized for high-current distribution while maintaining strict galvanic isolation to protect sensitive digital electronics from line-side transients.
