## Summary description

TracoPower TMR 3-4811WIR is a 3 W DC/DC converter designed for PCB or rail-mounted applications. It delivers a regulated 5 V output with up to 600 mA current from a 48 V DC input and provides a single isolated output in a SIP (SIL) package. Suitable for industrial control, telecom and embedded systems requiring compact isolated power.

## Long description

The TracoPower TMR 3-4811WIR is a compact 3 W DC/DC converter in a single in-line package (SIP) designed for PCB or rail-mounted installations. It accepts a nominal 48 V DC input and provides a regulated 5 V isolated output capable of supplying up to 600 mA. The module integrates isolation between input and output, making it suitable for applications that require galvanic separation and a small footprint in industrial control, telecom and embedded power systems.
Advantages
The converter offers a regulated 5 V output with up to 600 mA load capability in a low-profile SIP package that simplifies board-level or rail-mounted integration. Its isolated single output reduces noise coupling and enhances safety for mixed-signal and control circuits. The device’s 3 W power rating and fixed input-to-output conversion are optimized for compact power rails where space and reliable isolation are required.
Suitable for
 Industrial control systems and PLC modules requiring isolated low-voltage supplies
 Telecommunications equipment and remote powering applications fed from 48 V lines
 Embedded systems and single-board computers needing a compact 5 V supply
 PCB-mounted or DIN-rail-mounted power assemblies where space is limited
When it may not be suitable
This DC/DC converter is not intended for applications that require more than 3 W of output power or output currents above 600 mA. It is also unsuitable where multiple isolated outputs or adjustable output regulation are needed. For systems demanding very low output ripple or tight transient response beyond standard converter performance, additional filtering or an alternative regulator topology may be necessary.
Key specifications
 Input voltage: nominal 48 V DC
 Output voltage: regulated 5 V DC
 Maximum output current: 600 mA
 Output power: 3 W
 Output configuration: single isolated output
 Package type: SIP (single in-line)
How to use
Mount the converter on the target PCB or DIN rail according to the manufacturer’s mechanical and thermal guidelines. Connect the 48 V DC input to the input terminals observing polarity and ensure the output side is connected to the 5 V load while maintaining the required isolation clearances. Provide appropriate input and output decoupling close to the device if recommended by the system design, and observe derating for elevated ambient temperatures or reduced airflow to avoid exceeding the 3 W power rating.
What to consider before purchase
 Verify that the 48 V input source is within the converter’s allowable input range and that polarity protection is in place if needed
 Confirm the 5 V output and 600 mA current meet the load requirements including startup and transient currents
 Assess thermal conditions and mounting options to ensure reliable operation at the intended power level
 Determine whether isolation and single-output configuration match system safety and grounding requirements
Usage recommendations
For reliable performance, place input and output decoupling capacitors close to the converter pins, maintain adequate PCB creepage and clearance for isolation, and allow for airflow or heatsinking when operating near the device’s maximum power. Use additional filtering if the system demands lower noise or tighter transient control.
