Product Overview
The Woodward 5466-318 is a MicroNet TMR Kernel Power Supply Module. This device receives 24 Vdc from main power supplies. It regulates this input to a steady 5 Vdc output. The output provides up to 10 A of current capacity. This module powers all critical components within the kernel section of MicroNet TMR systems.
Technical Specifications
The Woodward 5466-318 has an input voltage of 24 Vdc ±10%. The output voltage is 5 Vdc ±5%. Maximum output current reaches 10 A. The module comes from the United States (USA).
Key technical parameters include:
Input Voltage Range: 21.6 Vdc to 26.4 Vdc
Output Voltage: 5 Vdc ±5% (4.75V to 5.25V)
Output Current: 10 A maximum
Product Type: MicroNet TMR Kernel PS Module
Health Indicator: Single LED for module status
The module generates a 5 Vdc precharge voltage for safe startup. This precharge enables gradual energization of system components. It protects against power surges during initial power-up.
Fault Tolerance and Redundancy
The 5466-318 contributes to impressive fault tolerance in MicroNet TMR systems. Each kernel section has its own individual power supply module. If one kernel power supply fails, other kernel sections continue operating independently.
Key fault tolerance features:
Independent operation: Each kernel section runs on its own supply
System functionality preserved: Failure in one section does not stop the whole system
High availability: Continuous operation despite power anomalies
Robustness: Designed for safety-critical applications
This architecture guarantees continuous operation. It handles unforeseen power supply issues without system interruption. The design makes it exemplary for nuclear power plants and aerospace systems.
Precharge and Startup Functions
The Woodward 5466-318 plays a pivotal role in startup sequences. It generates a controlled 5 Vdc precharge voltage. This precharge voltage enables safe and controlled system startup.
Precharge benefits include:
Gradual energization of system components
Protection from potential power surges
Avoidance of startup instabilities
Enhanced overall system reliability
Improved operational safety
By ensuring gradual power application, the module protects sensitive electronics. This is especially important in mission-critical control systems.
Installation Guidelines
Follow these steps for proper installation:
Install the 5466-318 in the first module slot from the left of each sub-chassis.
Place the Kernel CPU module in the next slot to the right.
Connect 24 Vdc ±10% input from the MicroNet main power supplies.
Observe the single LED for kernel power supply health status.
Do not install any other module type in the first slot position.
Verify the 5 Vdc output reaches all kernel components.
The sequential placement is imperative for correct configuration. Following this order ensures seamless operation. It also guarantees optimal performance of your MicroNet TMR system.
Health Monitoring
The Woodward 5466-318 includes a single LED indicator. This LED shows the kernel power supply health status. A normal LED indicates proper operation. Any LED anomaly suggests a power supply issue. Use this indicator during routine maintenance checks.
