DC/DC converter TracoPower TMDC 40-2411, 40 W, 5.1 V, 8 A, encapsulated

The TracoPower TMDC 40-2411 is an encapsulated DC/DC converter that provides a fixed 5.1 V output at up to 8 A with a maximum output power of 40 W. Designed for industrial and embedded systems, this compact module offers regulated, isolated power conversion in a space-saving encapsulated package suitable for board mounting where stable low-voltage supply and galvanic isolation are required.

Advantages

The encapsulated construction protects internal components from dust and mechanical stress while enabling reliable thermal performance in confined spaces. The converter features regulated output and electrical isolation between input and output, reducing interference and improving safety in mixed-signal environments. Its compact size and board-mountable format simplify integration into existing PCBs and help maintain consistent low-voltage rails for sensitive electronics.

Suitable for

• Industrial control systems and automation equipment
• Embedded systems and single-board computers needing isolated 5.1 V supply
• Telecommunications and network devices requiring low-noise regulated power
• Measurement and test instruments where isolation improves accuracy and safety
• Powering sensors, actuators, and peripheral modules on a common board

Key specifications

• Output voltage: fixed 5.1 V DC
• Maximum output current: 8 A
• Maximum output power: 40 W
• Encapsulated module for PCB mounting
• Regulated output with electrical isolation between input and output
• Compact footprint suitable for space-constrained assemblies

How to use

Install the module on the PCB following the manufacturer’s recommended mounting orientation and soldering guidelines to ensure proper thermal contact. Provide appropriate input voltage within the acceptable range for the converter and verify correct polarity before powering. Connect the 5.1 V output to the low-voltage rail, observe the maximum current rating to avoid overload, and include necessary upstream protection such as fuses or upstream current limiting. Ensure adequate ventilation or heat-sinking if the module operates near its maximum power for extended periods.

Usage recommendations

For reliable long-term operation, operate the converter below its maximum current when possible, add upstream protection against voltage transients, and follow PCB layout best practices for grounding and thermal dissipation to minimize noise and maintain isolation performance.
