The Woodward 5466-1001, also cataloged as the 5466-1001 Power Supply Module, operates as a dedicated hardware component for stable power distribution and voltage conversion within MicroNet digital controller platforms. The module converts 110 VAC or 125 VDC main input lines into a regulated 24 VDC output at up to 16 A, supplying continuous operating power across the backplane chassis while maintaining network galvanic isolation up to 1000 Vrms.

Hardware Specifications

Thermal Heat Sink Dissipation Profiles

The power supply chassis is engineered with optimized thermal heat sink dissipation profiles to withstand continuous operation in extreme environmental conditions. Utilizing heavy-duty aluminum conduction channels, the board dissipates heat generated by internal power electronics during 16 A load drops across an extended temperature window of -40 deg C to +105 deg C. This thermal management prevents voltage drift and thermal shutdown during peak demand cycles without requiring internal cooling fans.

Frequently Asked Questions

Q: What input power sources can be wired to the primary input terminals?

A: The module accommodates both AC and DC industrial power feeds, operating on either 110 VAC or 125 VDC utility inputs without requiring physical jumper selection.

Q: How does the integrated network isolation protect backplane electronics?

A: The onboard isolation circuitry provides 1000 Vrms isolation across 0-60 Hz line frequencies, preventing high-voltage line surges and ground loops from transferring to sensitive controller backplane logic.

Q: What is the maximum permitted length for the secondary power stub connections?

A: Secondary power stub wiring must not exceed a maximum length of 300 mm to ensure low trace resistance and prevent voltage drops under high current loads.

Field Installation Guidelines

1. Mount the module firmly into the designated chassis power slot, securing top and bottom mounting panel screws to establish earth ground contact with the rack enclosure.
2. Verify that primary power feed lines (110 VAC or 125 VDC) are de-energized prior to landing wiring onto input terminal blocks.
3. Wire the main input lines using 14 AWG stranded copper conductors rated for high-temperature service, ensuring tight terminal screw torque.
4. Keep secondary 24 VDC power distribution stub wiring below the 300 mm maximum length specification to minimize inductive line noise and voltage drops.
5. Apply input power and verify that the output voltage stabilizes at 24 VDC before bringing connected controller I/O modules online.
