Alimentations MicroNet Plus PS - entrée 220 VAC Woodward 5466-1002

The Woodward 5466-1002 is a heavy-duty, high-capacity power supply module designed for the MicroNet Plus control system. This 2-slot wide module provides reliable, stabilized power to the system's VME backplane, supporting large-scale control architectures used in steam turbines, gas turbines, and compressor sets.

Technical Specifications

Installation Guidelines

• Chassis Placement: Due to its 2-slot width and weight, ensure the module is properly aligned with the guide rails in the MicroNet Plus chassis. Tighten the faceplate screws securely to ensure proper grounding and to prevent vibration-induced disconnection.

• Input Wiring: Verify the input voltage matches the 220 VAC specification. Ensure the power source is fused according to Woodward’s system manual to protect the module from external surges.

• Heat Management: Power supplies generate significant heat. Ensure the chassis cooling fans are operational and that there is adequate clearance above and below the rack for vertical airflow.

• Redundancy Configuration: In many MicroNet Plus setups, power supplies are installed in redundant pairs. If using a secondary supply, ensure it is connected to a separate power circuit to maximize system uptime.

Frequently Asked Questions (FAQs)

Does this power supply support DC input as well?

Yes, the 5466-1002 is designed to handle 220 VAC as well as high-voltage 250 VDC inputs, providing flexibility for different industrial power plant standards.

Is this module hot-swappable?

In a redundant power configuration, a single power supply module can typically be replaced while the system is running. However, always refer to your specific MicroNet Plus hardware manual to ensure the "Live Insertion" protocols are followed to avoid system trips.

What do the front panel LEDs indicate?

The module features status LEDs that monitor the output health of various voltage rails (+5V, +24V, etc.). A green light normally indicates the rail is within tolerance, while a red light or an unlit LED indicates a power failure or fault.

Why is the shipping weight so high (23 kg)?

MicroNet Plus power supplies use industrial-grade transformers, high-capacity capacitors, and substantial heat-sinking to ensure a long service life and the ability to drive dozens of I/O modules simultaneously.
