Functional Description

5461-117 is a Power Supply - 301 developed by Woodward. The power supply chassis employs redundant power supplies. A motherboard located on the back of the power supply chassis allows the two power supplies to form a redundant power system, providing six separately regulated 24 Vdc, 6 A outputs to the control.


  • When redundant power supplies are in use, current sharing circuitry balances the load to reduce heat and improve power supply reliability. If one of the power supplies fails, this feature allows for the power supplies to be replaced while the control is still running. Each main power supply has four LEDs that indicate the health of the power supply (OK, Input Fault, Overtemperature, and Power Supply Fault). Connections to the main power supply are made via terminals on the front of the power supplies. The power supply chassis is linked to the control chassis via a 50-pin ribbon cable.
  • The ribbon cable connects to a connector on the TMR Main Chassis's back underside. There are connectors beneath the A and C Kernels that can be used in either direction.
  • The cable connects to the Power Supply Chassis near the back of the upper side of the Chassis. Because the Power Supply Ribbon cable is only one foot long, the TMR PS Chassis must be placed directly beneath the A or C Kernels of the TMR Main Chassis.

Frequently Asked Questions

What is 5461-117?
It is Power Supply - 301 developed by Woodward.

What are the output specifications?
The power supply chassis provides six separately regulated 24 Vdc outputs. Each output can deliver up to 6 A of current, ensuring sufficient power for the connected control system.

How can a failed power supply be replaced without interrupting the control system?
In the event of a power supply failure, the redundant design allows for easy replacement without interrupting the control system's operation. The functioning power supply continues to power the system while the faulty one is being replaced.

How are the power supplies connected in the chassis?
The connections to the main power supplies are made via terminals located on the front of the power supply units. These terminals provide a convenient interface for connecting power input and output cables.

How is the ps chassis linked to the control chassis?
The power supply chassis is connected to the control chassis through a 50-pin ribbon cable. The ribbon cable is connected to a specific connector on the TMR (Triple Modular Redundant) Main Chassis's back underside. The cable can be attached to connectors beneath the A and C Kernels in either direction.
