TMH2405S - Traco Power

TMH2405S Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Traco Power recommends a PCB layout with a large copper area connected to the module's thermal pad to dissipate heat efficiently. A minimum of 2 oz copper thickness is recommended, and the copper area should be connected to a heat sink or a metal plate for further heat dissipation.
• How do I ensure the module's reliability in high-vibration environments?
  To ensure reliability in high-vibration environments, Traco Power recommends securing the module to the PCB using screws or adhesive, and ensuring that the PCB is properly secured to the chassis or enclosure. Additionally, the module's pins should be soldered securely to the PCB to prevent vibration-induced fatigue.
• What is the maximum capacitance I can use on the output?
  The maximum capacitance on the output of the TMH2405S is 2200uF. Exceeding this value may cause instability or oscillation in the module. It's recommended to use a capacitance value that is within the specified range to ensure stable operation.
• Can I use the TMH2405S in a redundant configuration?
  Yes, the TMH2405S can be used in a redundant configuration to achieve high availability and reliability. However, it's essential to ensure that the modules are properly synchronized and that the system is designed to handle the redundancy correctly.
• What is the recommended input fuse rating?
  Traco Power recommends using a fuse with a rating of 2A to 5A, depending on the specific application and input voltage. The fuse should be able to handle the maximum input current and provide adequate protection against overcurrent conditions.
