The 5501-467 (Model: 5501-467) is a high-performance Main Power Supply (PS) module designed for the Woodward MicroNet™ Simplex control platform. This module is engineered to provide stable, regulated DC power to the MicroNet chassis, supporting critical processing and I/O functions for gas turbines, steam turbines, and large industrial compressors. The 5501-467 (Part Number: 5501-467) is distinguished by its versatile input capabilities, accommodating both low-voltage DC environments (24 Vdc) and high-voltage AC/DC configurations (120 Vac/Vdc), making it a flexible solution for global industrial power standards.
In high-stakes turbine environments, power integrity is non-negotiable. The 5501-467 (Main PS: 5501-467) incorporates advanced holdup circuitry—providing 1 cycle at 120 Vac—to ensure the control system "rides through" momentary power dips without triggering a processor reset. While this specific module is a Simplex (non-redundant) version, it maintains the same industrial-grade durability and fault-monitoring LEDs found in Woodward's TMR systems, including status indicators for Input Fault, Power Supply Fault, and Overtemperature.
The 5501-467 (5501-467) provides robust energy conversion across a wide range of input conditions.
