FUNCTIONAL DESCRIPTION:

The 5417-168 is a high-integrity High-Voltage Power Supply (HVPS) module designed and manufactured by Woodward for the MicroNet and MicroNet Plus digital control platforms. This module is the primary energy source for the control system's backplane, converting utility-level AC or high-voltage DC into the stabilized low-voltage DC rails required by the CPU, communication modules, and I/O packs. Designed for the high-availability demands of turbine and engine management, the High Voltage Power Supply ensures that critical control logic remains operational even during industrial power fluctuations.

POWER DISTRIBUTION & SYSTEM STABILITY:

The High Voltage Power Supply is designed to provide clean, filtered power across the MicroNet chassis. It features an integrated soft-start circuit to prevent high inrush currents that could damage sensitive downstream electronics. By maintaining tight regulation of the +5V and ±15V logic rails, the power supply prevents data corruption and processor resets, ensuring that the GAP (Graphical Application Programmer) logic executes without interruption.

REDUNDANCY & FAULT TOLERANCE:

In mission-critical applications, the MicroNet chassis is typically configured with two power supplies (dual redundancy). The 5417-168 includes:

• Diode OR-ing: Internal circuitry that allows two power supplies to share the load. If one unit fails, the other takes over the full load instantaneously without a system glitch.

• Status Monitoring: The module communicates its health status to the CPU. If the input power fails or an internal fault is detected, a Power Supply Alarm is triggered, allowing maintenance personnel to replace the unit while the turbine is still running (Hot-Swappable capability).

RUGGEDIZED PROTECTION:

The High Voltage Power Supply is equipped with robust protective features:

• Transient Suppression: Integrated filters protect the control system from spikes and surges on the mains line.

• Thermal Management: The unit is designed for efficient heat dissipation, allowing it to operate at full capacity within the high-temperature enclosures of a turbine control cabinet.

• Galvanic Isolation: Ensures that electrical noise on the input side does not migrate into the sensitive control logic.

FREQUENTLY ASKED QUESTIONS:

What is the 5417-168?

It is a High-Voltage Power Supply module used in Woodward MicroNet systems. It takes high-voltage AC or DC input and converts it into the necessary voltages to power the control system's internal hardware.

Does this power supply support redundant configurations?

Yes. The High Voltage Power Supply is designed to work in a redundant pair. If the chassis has two power supply slots, two units can be used to ensure the system stays online even if one supply or power source fails.

What is the difference between this and a Low-Voltage Power Supply (LVPS)?

The 5417-168 (HVPS) is designed for 110V/120V mains or high-voltage battery banks. A Low-Voltage Power Supply (LVPS) is typically designed for 24V DC input environments. Ensure your input power source matches the HVPS specifications before installation.

What happens if the input voltage drops below the specified range?

The High Voltage Power Supply includes undervoltage detection. If the input power becomes insufficient to maintain the logic rails, the module will trigger a power-fail signal to the CPU, allowing for an orderly shutdown or a switch to the redundant supply.
