When a power supply fails in a critical turbine control system, the Woodward 5466-1001 Digital Controller Power Supply Module provides a robust solution. Designed for MicroNet TMR and redundant systems, this module integrates current sharing circuitry that balances load across supplies, reducing heat and enhancing reliability. If one supply fails, you can replace it while the control remains operational—minimizing downtime. Four front-panel LEDs (OK, Input Fault, Overtemperature, Power Supply Fault) offer immediate visual diagnostics, enabling rapid troubleshooting.

Troubleshooting and Fault Diagnostics
The Woodward 5466-1001 power supply includes four LEDs for health monitoring. The Power Supply Fault LED illuminates red when one of the four internal converters fails. If this occurs, first check for a short circuit on external devices connected to the supply. When the short is removed, normal operation resumes. If no short is found, power off the unit for one minute to reset it. Ensure the module is fully seated on the motherboard connector. If the issue persists, replace the unit. This diagnostic approach aligns with common failure modes, allowing operators to quickly isolate and fix problems without extensive downtime.
Industry Applications
The Woodward 5466-1001 is ideal for turbine control systems in hydro, gas, and steam power generation, as well as diesel engine management. In a gas turbine application, redundant 5466-1001 units share load equally, ensuring seamless operation even if one supply fails. The high network isolation (1000 Vrms) protects against ground loops in noisy industrial environments. Its compact dimensions (H461 mm x W265 mm x D59 mm) allow integration into standard MicroNet chassis.
Selection Guide and Purchasing Advice
Before purchasing the Woodward 5466-1001, verify that your system’s power requirements match the 24 VDC, 16 A output. For redundant setups, ensure that the input source is sized so each supply can handle the full load individually—do not size for the sum of both. Multiple chassis with MicroNet supplies can share the same source, but avoid connecting a redundant pair to a single source to prevent total failure.
