Woodward 5466-1049 MicroNet TMR Plus Kernel Power Supply

The Woodward 5466-1049, also cataloged as the 5466-1049 Kernel Power Supply, serves as the primary 5466-1049 Module utilized to execute highly regulated power distribution across MicroNet TMR Plus platforms.

Hardware Specifications

Industrial Drives, Governors, and Speed Control Properties

The module operates directly within turbine-skid environments, managing the actuator loop feedback response limitations by delivering a ripple-stabilized 5 VDC bus to the primary TMR5200 CPU. The internal hardware architecture utilizes a dedicated thermal heat sink dissipation profile to mitigate localized temperature spikes under maximum 10 A current deployment conditions. To counteract high-frequency noise generated by adjacent variable frequency drives or electronic governor switching circuits, the module integrates internal harmonic distortion suppression stages alongside heavy electromagnetic interference (EMI) industrial shielding.

Frequently Asked Questions

Q: How does the 5466-1049 execute power redundancy without causing interruption to the TMR5200 CPU?

A: The module contains three independent internal power paths that run concurrently. If a fault develops within a single internal path, the internal Triple Modular Redundant (TMR) logic seamlessly maintains the regulated 5 VDC output without experiencing dropouts or switching delays.

Q: Can this power supply module handle fluctuations beyond the nominal 24 VDC input rating?

A: Yes. The high-efficiency industrial switching regulator accommodates a broad physical input tolerance window spanning from 18 VDC up to 32 VDC, protecting downstream digital electronics from voltage transients and common-mode input variations.

Field Installation Guidelines

• Chassis Grounding and EMI Isolation: Mount the power supply securely within the MicroNet TMR Plus chassis framework. Ensure direct metal-to-metal contact with the enclosure backplane to establish a low-impedance electrical path for the industrial shielding, which is vital for suppression of localized turbine-skid EMI.
• Thermal Mitigation Clearances: Maintain unobstructed air channels around the module casing. The integrated thermal heat sink relies on standard convective airflow across its external surfaces to stay within the 0 to +55 deg C operating envelope during continuous 10 A service.
• Input Wiring Integrity: Field wiring feeding the 24 VDC input must use heavy-gauge, stranded copper conductors to minimize voltage drops across the terminal links. Ensure all terminal connection screws are torqued according to standard industrial panel schedules to mitigate resistance-induced heating.
