Traco Power TMPW 50-112-T AC/DC Power Converter 50W 12V

The Traco Power TMPW 50-112-T is a high-efficiency 50W AC/DC power converter designed for reliable performance in demanding environments. Housed in a compact, encapsulated plastic case, this unit provides a stable 12V output while supporting a wide AC input voltage range of 90-305 V and a DC input range of 100-430 V. It is engineered to meet the requirements of both industrial and household building technology applications, offering a robust solution for space-constrained designs.

Advantages

This power converter features an extended input voltage range, allowing it to operate effectively with 480 VAC three-phase supply voltages commonly found in heavy industrial settings. By supporting higher input voltages, the device helps reduce the current drawn from the load, facilitating a more compact and lightweight system architecture. The unit includes an internal EN 55032 class B filter, which eliminates the need for additional external filtering components and saves valuable board space. Furthermore, it offers high I/O-isolation of 4000 VAC and operates reliably across a wide temperature range from -40 to +70°C, ensuring durability in diverse conditions.

Suitable for

• Industrial automation systems
• Household and building technology equipment
• Applications requiring protection class II compliance
• Systems where space-saving and high efficiency are critical
