Woodward 5501-380 MicroNet PLC Power Supply Module

Description

The Woodward 5501-380 is a robust AC-input power supply module designed specifically for the MicroNet control system architecture. This panel-mount unit converts standard 120 VAC utility power into the regulated DC voltages required by the MicroNet backplane and its associated I/O modules. Engineered for high-availability environments such as steam turbine control, gas compression stations, and large-scale power plants, the 5501-380 provides stable energy delivery even under fluctuating load conditions. Its heavy-duty construction and high MTBF rating make it a critical component for reducing unscheduled downtime and ensuring the long-term reliability of industrial control racks.

Features

• Designed for seamless integration with the Woodward MicroNet control system.
• High-efficiency switching topology to minimize heat dissipation and improve system longevity.
• Integrated protection circuitry including over-voltage, over-current, and short-circuit safeguards.
• Internal filtering circuits to suppress electromagnetic interference (EMI) and line transients.
• Front-panel status indicators for real-time power health monitoring and diagnostic troubleshooting.
• Rugged panel-mount chassis engineered for industrial thermal convection.

Applications

The 5501-380 power supply is utilized in mission-critical industrial automation applications, including:

• Steam and gas turbine control systems.
• Gas compression station control.
• Large-scale power generation and distribution plants.
• Industrial process control racks requiring high-reliability DC power.

Technical Specifications

Installation Guidelines

• Ensure the control cabinet provides adequate ventilation to maintain operating temperatures within the 0 to 60 deg C range.
• Verify that the input power source is within the specified 120 VAC nominal range before connection.
• Always power down the MicroNet rack before inserting or removing the power supply module to prevent electrical arcing or damage to backplane pins.
• Ensure the chassis is securely mounted and properly grounded to the cabinet backplane to maintain EMI shielding effectiveness.
• Route high-voltage AC input wiring away from low-voltage signal cables to minimize potential noise coupling.

FAQ

Is the 5501-380 compatible with all MicroNet systems?

The 5501-380 is designed for the MicroNet architecture; however, always verify your specific system configuration and backplane requirements against the module's output specifications before installation.

What do the status indicators on the front panel signify?

The status indicators provide visual confirmation of the power supply's operational health. If an indicator is off or flashing, it typically signals an over-voltage, over-current, or internal fault condition requiring immediate inspection.
