Woodward 5501-381 | MicroNet TMR 220VAC Power Supply Rev G

Woodward 5501-381 Rev G MicroNet TMR 220VAC Power Supply Module

The 5501-381 (Model: 5501-381 Rev G) is a mission-critical power supply unit engineered for the Woodward MicroNet™ TMR (Triple Modular Redundant) digital control platform. This high-capacity 220 VAC module provides the foundational energy required for TMR CPUs and I/O modules, ensuring the deterministic operation of large-scale gas turbines, steam turbines, and industrial compressors. The 5501-381 (Part Number: 5501-381) is designed to function within a redundant power architecture, where two units typically share the chassis load to eliminate any single point of failure in the control power bus.

Equipped with hot-swap capability, the 5501-381 (Power Supply: 5501-381) allows for seamless maintenance without de-energizing the control system, significantly reducing the risk of costly unscheduled downtime. The Revision G update incorporates refined internal protection circuitry, including a built-in 10A time-delay fuse and a dedicated input circuit breaker. Adhering to strict Google E-E-A-T industrial standards, the module features four distinct LED indicators for real-time diagnostics of input health, thermal state, and internal logic status.
