Product Overview

The Woodward 5501-467 Rev. C constitutes the primary energy backbone for the MicroNet Simplex control platform. Engineered specifically for high-demand turbomachinery applications, this power supply module converts high-voltage AC or DC inputs into the stabilized DC rails required by sensitive CPU and I/O cards. It plays a decisive role in the reliability of gas and steam turbine control systems by providing a consistent 5 VDC output, even under fluctuating load conditions. Its heavy-duty construction minimizes electrical noise, maintaining a sound level below 70 dBA, which is critical for preventing signal interference in high-precision monitoring environments. Whether powering a MicroNet Plus or Simplex chassis, this module ensures your critical control logic remains energized during grid instability.

Core Technical Advantages

This module utilizes a versatile input architecture, accepting an expansive 180-264 VAC range and high-voltage DC inputs. This dual-input capability provides engineers with significant flexibility when designing power redundancy schemes in industrial plants.

The front faceplate integrates four high-visibility LED indicators, allowing maintenance teams to verify power health at a glance. These indicators monitor internal status and immediately signal a fault if the output deviates from safety parameters. Furthermore, the 5501-467 provides temperature-dependent current scaling, delivering up to 32.0 A at 55 °C, which ensures the control system remains fully operational even in poorly ventilated or high-ambient heat environments. The Rev. C hardware revision includes optimized holdup time (7 ms @ 225 VDC), offering a vital buffer during momentary voltage dips.

Technical Specifications

Installation & Engineering Guide

Successful deployment of the 5501-467 requires strict adherence to wiring standards. Engineers must utilize 14 AWG (2.5 mm²) copper wire rated for at least 60°C to handle the high-current throughput without thermal degradation.

When installing into a MicroNet chassis, ensure the module is fully seated and the faceplate screws are hand-tightened to maintain proper grounding contact with the chassis frame. Because this power supply weighs 48 lbs when integrated, verify that the cabinet racking is rated for the total weight of a fully populated MicroNet system. For high-altitude installations up to 4000m, keep airflow paths clear, as air density affects the cooling efficiency of the internal heat sinks. Always verify the input voltage levels match the "High Voltage" configuration before applying power to prevent catastrophic damage to the internal rectifier bridge.

Engineering Advantages

The Woodward 5501-467 excels in durability compared to standard industrial power units. Its ability to operate in Simplex mode within a MicroNet Plus chassis provides a cost-effective solution for non-redundant critical paths without sacrificing the high-voltage input capability required by utility-scale power plants. The robust design ensures seamless compatibility with Turbo System Integrity (TSI) protocols, providing the stable power rails necessary for high-speed deterministic processing in Woodward’s most advanced control logic controllers.

Technical FAQs

Q1: Can the 5501-467 be used in a redundant power configuration?

A1: While this specific module is compatible with MicroNet Plus chassis, it is designed for Simplex (non-redundant) system operations. For full redundancy, dual power supply configurations using compatible Woodward redundant models are required.

Q2: What do the four LED indicators represent?

A2: They provide real-time diagnostics for Input Power, Internal DC Health, Output Status, and a dedicated Power Supply Fault indicator to facilitate rapid troubleshooting.

Q3: Does the module require derating at higher altitudes?

A3: The module is rated for use up to 4000m; however, please note that current output is temperature-dependent. At maximum altitude, monitor the ambient temperature to ensure it does not exceed the 55°C threshold for full 32A output.

Q4: What is the significance of "Revision C"?

A4: Revision C incorporates updated component specifications that improve the holdup time and thermal resilience compared to earlier versions (Rev A or B), ensuring better performance during power transients.
