Features:
- Wide-Temperature Industrial Hardening
- Precision Output Regulation with Protection Suite
- High-Efficiency DC/DC Conversion Architecture
The WOODWARD 5438-667 operates reliably across a -40°C to +85°C temperature range, ensuring continuous power delivery in extreme environments from arctic field installations to desert-based turbine control rooms.
Maintaining ±0.1% load regulation, the WOODWARD 5438-667 provides stable power even under fluctuating load conditions, while integrated overvoltage, overcurrent, short-circuit, and overtemperature protection safeguards connected control modules from electrical faults.
With efficiency ratings reaching 95%, the WOODWARD 5438-667 minimizes energy loss and thermal buildup within control cabinets, reducing cooling requirements and improving long-term reliability in densely populated chassis installations.
The 5438-667 Woodward 125V DC/DC Power Supply Module still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Extended Thermal Management:Designed to operate reliably in harsh industrial enclosures, the module handles wide ambient temperature fluctuations (typically ranging from 0 to +55℃ or higher depending on the specific chassis ventilation configuration). It employs advanced thermal dissipating materials to prevent internal localized hotspots without relying on failure-prone individual component fans.
- Conformal Coating for Atmospheric Resistance:The printed circuit boards within the module feature industrial-grade conformal coating. This provides a robust barrier against environmental contaminants, protecting delicate circuitry from high relative humidity, salt spray on offshore platforms, and conductive particulates as categorized under IEC 60664-1 Pollution Degree 2.
- High Shock and Vibration Resilience:Engineered to survive the heavy mechanical stress typical of turbine halls and marine engine rooms, the unit is constructed with structurally reinforced chassis-mounting mechanisms. It resists low-frequency mechanical vibrations and sudden high-impact physical shocks from surrounding heavy machinery.
- Industrial Electrodynamic Stress Tolerance:The unit is engineered to run on fluctuating, unfiltered 125 VDC inputs from industrial battery banks that are frequently subjected to charging spikes, ripples, and heavy load switching. It features extensive internal buffering and filtering to output smooth, ripple-free power despite severe input voltage drops or surges.
- Hazardous Location Approvals (Class I, Division 2 / Zone 2):The module complies with stringent global standards for explosive environments, including North American CSA Class I, Div. 2 and European ATEX/IECEx Zone 2 certifications. This ensures that the module’s electrical components will not act as an ignition source under normal operation or specific fault conditions within volatile atmospheres.
- Electromagnetic Compatibility (EMC) Directive:Certified to the CE EMC Directive, the power supply demonstrates high immunity to electromagnetic interference (EMI) and radio frequency interference (RFI) emitted by heavy industrial drives and switchgear. Simultaneously, it maintains low emissions to prevent disrupting nearby sensitive analog instrumentation or communication busses.
- Comprehensive Internal Fault Monitoring & Telemetry:Safety is enhanced by built-in diagnostic infrastructure. The unit actively communicates its health status back to the MicroNet CPU or signals via dedicated front-panel LEDs—tracking parameters like input faults, internal power supply faults, and overtemperature thresholds to facilitate predictive maintenance before a critical failure occurs.
- Electrical Isolation and Low Voltage Directive (LVD):Adhering to international electrical safety frameworks like the CE Low Voltage Directive, the 5438-667 incorporates heavy galvanic isolation between its high-voltage 125 VDC input and the low-voltage logic outputs. This protects both the underlying MicroNet control processors and the technicians interacting with the system from high-voltage faults or ground loops.
- Critical Prime Mover Controls:The module is universally deployed within Woodward MicroNet systems configured for the control and protection of high-asset prime movers, such as heavy-duty gas turbines, industrial steam turbines, large-scale compressors, and hydro-turbines. Its main role is to safeguard the system against power fluctuations, preventing catastrophic trips in high-inertia machinery.
- Mission-Critical Utility & Power Generation:It is widely adopted in power generation facilities where 125 VDC station battery banks are the standard utility-grade backup architecture. The power supply integrates seamlessly with these DC grids to ensure uninterruptible control loop execution during main AC power disruptions.
- Continuous Process Industries:In environments like chemical processing, petrochemical manufacturing, and refining, any control system shutdown means massive production loss. The 5438-667 is built into redundant power chassis schemes (supporting hot-swapping), making it indispensable for processes demanding 24/7/365 continuous operations.
- Upstream & Downstream Oil and Gas Platforms:This power supply is highly suited for offshore drilling rigs, marine transportation vessels, and onshore pipeline distribution stations. In these applications, it energizes the complex governor and safety-interlock systems that regulate massive fuel valves and emergency isolation mechanisms.
