Description
Product Overview
Part Number: 5466-318 Manufacturer: Woodward） Product Series: MicroNet TMR Turbine Control System Type: TMR Kernel Power Supply Module
5466-318 is the dedicated kernel power supply module for Woodward MicroNet TMR triple redundant turbine control rack. It takes 24VDC input from the system main power supply and converts it to regulated 5VDC, max 10A, to power TMR040 CPU and all core kernel logic boards. It also provides 5V pre-charge voltage for controlled power-up sequence, protecting critical kernel components from inrush surge during system startup. It is installed in the VME-style MicroNet TMR chassis and works exclusively paired with TMR040 CPU module. Widely deployed in gas and steam turbine TMR control systems for power generation plants as critical spare part for maintenance and retrofit.

Engineer Notes
- 5466-318 is TMR kernel power supply only. It must be matched with TMR040 CPU module inside MicroNet TMR chassis and cannot work standalone.
- Its main function is supplying stable 5V power for the TMR kernel control logic; it is different from the rack main 24V power supply.
- Built-in precharge circuit for soft startup to suppress inrush current and avoid damage to sensitive kernel boards.
- Single LED on front panel, simple status indication for power good / fault diagnosis.
- Not hot-swappable. Cut off rack power before removing or inserting this module.
- Conformal coated PCB offers protection against dust and mild corrosive gas in power plant control cabinet.
- This legacy MicroNet TMR module is end-of-life original production, mainly used for plant spare inventory and turbine control system overhaul.
Pre-Shipment Test Protocol
- Visual inspection of PCB, front panel, edge connector, component and part number marking
- Power loading test: verify stable 5VDC output under full 10A load
- Pre-charge startup sequence functional test
- Over-current protection test
- LED indicator status verification
- Backplane edge connector continuity and insulation resistance test
- Hardware revision and label verification
- Anti-static & shockproof packaging inspection
