Product Description
Woodward 5501-432 MicroNet Simplex Power Supply Module
Product Overview
- The Woodward 5501-432 is a MicroNet Simplex Power Supply Module designed to provide reliable power to Woodward’s MicroNet control system, which is used for controlling industrial gas turbines, steam turbines, and compressors in applications such as power generation, oil and gas, and marine systems. This module supplies regulated DC power to the MicroNet chassis, supporting critical components like CPU modules (e.g., 5501-381) and I/O modules. The 5501-432 is a simplex (non-redundant) power supply, suitable for applications where high reliability is needed but redundancy is not required. It features robust diagnostics and fault tolerance to ensure stable operation in demanding environments. Compared to Woodward’s MicroNet TMR power supplies or genset controllers (e.g., EasyGen-3200-5, 8440-2050E), the 5501-432 is a specialized power module, not a control or protection device. It is distinct from Woodward’s protection relays (e.g., XD1G11), servo position controllers (e.g., 8200-226), communication modules (e.g., SST-ESR2-CLX-RLL), excitation systems (e.g., DECS-100-B15), electronic governors (e.g., DYN1-10784-003-0-12), and actuators (e.g., 8408-921).
