FUNCTIONAL DESCRIPTION:
The 5461-975 Low Voltage Power Supply Module is the primary energy regulation hub for Woodward MicroNet and NetCon 5000 control systems. Designed as a high-efficiency DC-DC converter, it transforms raw 24 VDC industrial power into the multiple stabilized voltage rails required by the system backplane. This module ensures that the Master CPU and various I/O modules receive consistent, noise-free electricity, which is fundamental for maintaining the deterministic timing of critical turbine control loops. By delivering a steady power stream, the Power Supply Module prevents digital logic errors and ensures the high-speed processing necessary for real-time governor operations.
THERMAL RESILIENCE AND PASSIVE COOLING:
Engineered for the demanding environments of turbine enclosures and industrial control rooms, the Low Voltage Power Supply Module utilizes an integrated heavy-duty aluminum heat sink faceplate. This passive cooling architecture eliminates the need for internal mechanical fans, which are often susceptible to failure in high-vibration or dust-prone settings. The internal components are rated for sustained performance at temperatures up to +70 °C, ensuring that the power supply maintains peak efficiency without thermal derating, even during heavy system loads or high-ambient temperature events.
REDUNDANCY AND ZERO-DOWNTIME HOT-SWAP:
In high-availability power generation applications, the Power Supply Module is frequently deployed in a dual-redundant configuration. These modules feature active load-sharing logic, allowing two units to balance the system's power requirements simultaneously. Should one module experience an input loss or internal fault, the redundant unit assumes the total load instantaneously without a millisecond of interruption. This seamless hardware-level transition prevents unplanned turbine trips and allows maintenance teams to replace a faulty module while the control system remains fully energized and operational.

What is the Woodward 5461-975?
It is a Low Voltage Power Supply (LVPS) module used in MicroNet and NetCon systems. It acts as the central power converter, taking 24 VDC input and providing the regulated +5V, +24V, and ±15V DC rails needed for the system's internal modules and backplane to function.
What is the primary use of the Woodward 5461-975?
This module is used to provide a stabilized power source for the entire control chassis. It is the heart of the system, ensuring that the sensitive digital processors and analog I/O cards are protected from electrical noise and fluctuations in the main industrial power supply.
Can this module be replaced while the system is running?
Yes, if the MicroNet chassis is configured with redundant power supplies, the Power Supply Module is hot-swappable. The secondary power supply will automatically carry the full system load during the replacement process, ensuring there is no downtime for the turbine or engine.
What happens if the input voltage fluctuates?
The Power Supply Module features a wide input range (18–32 VDC) and integrated surge suppression. It is designed to filter out the dirty power typical of industrial environments. If the input voltage falls completely outside of the safe operating range, the module’s protection circuitry will trigger a safe shutdown to prevent damaging the sensitive backplane components.
