Traco Power’s new TCI line focuses on maximizing the proficiency of conduction cooled systems as it offers superior temperature behavior when mounted on a metal chassis or baseplate. This way the TCI 500U can deliver up to 90% of the maximum output power without the need for a fan. Excellent efficiency of up to 92% allows the TCI series to operate from –30 to +50°C without derating, while going up to +80°C with either load derating or forced cooling. They also meet OVC III requirements and can operate at up to 5000 m altitude. Active power factor correction, EMC characteristics dedicated for applications in industrial/automation and test & measurement fields and high reliability make the new TCI line an ideal solution for any demanding industrial application. ## **Models** |**Order Code**|**Output Power**
