DC/DC converter TracoPower TMDC 40-2415, 40 W, 24 V output, 1.67 A, encapsulated

The TracoPower TMDC 40-2415 is an encapsulated DC/DC converter delivering up to 40 W of regulated output power with a nominal 24 V DC output at 1.67 A. Built for industrial and embedded environments, this compact module provides galvanic isolation between input and output rails and stable voltage conversion for applications that require a sealed, robust power stage. The enclosed design helps protect internal components from dust and mechanical contact while simplifying integration into distributed power systems and battery-backed equipment.

Advantages

The encapsulated construction offers mechanical protection and straightforward mounting without additional enclosures. Galvanic isolation supports safe interfacing between different DC domains and reduces noise coupling. Tight output regulation maintains a steady 24 V supply under varying input conditions and load, and the converter’s thermal characteristics enable reliable operation within its rated power envelope. Its compact footprint makes it suitable where space is limited.

Suitable for

• Industrial control and automation power rails
• Battery-powered systems and backup power conditioning
• Embedded systems and distributed power architectures
• Instrumentation and measurement equipment requiring isolated supplies

Key specifications

• Output power: 40 W
• Nominal output voltage: 24 V DC
• Maximum output current: 1.67 A
• Encapsulated (sealed) module design
• Galvanic input-to-output isolation
• Designed for industrial and embedded use

How to use

Connect the DC input according to the converter’s polarity markings and observe the specified input voltage range for the module. Mount the encapsulated unit on a suitable surface with adequate clearance for airflow; follow the manufacturer’s thermal derating guidelines when operating near the 40 W limit. Verify output voltage with a meter before connecting sensitive loads, and use appropriate wiring and fusing on both input and output sides to protect against short circuits or overloads.

Usage recommendations

For reliable long-term operation, ensure adequate cooling and avoid operating continuously at maximum rated power without proper thermal management. Use the converter within specified input voltage and ambient temperature ranges, and add external filtering or transient suppression if the installation is exposed to high electrical noise or load transients.
