DC/DC converter TracoPower TEM 3-0523N, 3 W, 15 V output, 100 mA, DIL-24

TracoPower TEM 3-0523N is a 3 W DC/DC converter in a DIL-24 through-hole package that provides a regulated isolated 15 V output at up to 100 mA. Designed for board-level power conversion, this module delivers galvanic isolation between input and output, making it suitable for industrial control, instrumentation, and embedded systems requiring compact, low-power isolated supplies. The DIL-24 form factor allows mounting in standard through-hole sockets or direct PCB insertion.

Advantages

The converter offers electrical isolation to protect sensitive circuitry and reduce ground-loop issues. Its compact DIL-24 package simplifies integration into existing PCB layouts and supports through-hole assembly methods. With a 3 W power rating and stable 15 V output under light to moderate loads, the unit provides predictable performance for low-power applications. The module's design focuses on reliable board-level conversion with a small footprint and straightforward mechanical mounting.

Suitable for

• Isolation of control signals in industrial automation and PLC systems
• Powering sensors and transducers in instrumentation where isolation is required
• Embedded systems and microcontroller boards needing a small isolated supply
• Retrofit or prototype PCBs using through-hole socketed modules

Key specifications

• Output voltage: 15 V DC
• Output current: up to 100 mA
• Maximum output power: 3 W
• Package type: DIL-24 through-hole module
• Function: isolated DC/DC voltage conversion for board-level use

How to use

Install the converter into a compatible DIL-24 socket or solder it directly to the PCB following the board manufacturer’s land pattern. Observe correct orientation and ensure proper input polarity and connection to the primary supply. Provide adequate spacing and trace clearance for the isolated input/output regions. Verify output voltage under intended load and confirm that thermal conditions remain within component limits during operation.

Usage recommendations

Use short, low-inductance wiring for input and output connections and add appropriate input filtering or decoupling near the module when required by the application. Ensure the converter’s isolation rating meets system safety requirements and maintain creepage and clearance distances on the PCB. Avoid exceeding the rated output current and thermal limits to ensure long-term reliability.
