TRS2-1211 Frequently Asked Questions (FAQs)

  • Traco Power recommends using a low-ESR ceramic or film capacitor with a voltage rating of at least 1.5 times the input voltage. A 10uF to 22uF capacitor is a good starting point.
  • The TRS2-1211 is rated for operation up to 80°C, but derating is required above 60°C. Consult the datasheet for derating curves and ensure proper heat sinking and airflow to maintain reliable operation.
  • The TRS2-1211 meets various safety standards, including UL60950-1, EN60950-1, and IEC60950-1. However, it's essential to review the specific requirements for your application and ensure the module is used within its specified ratings and guidelines.
  • The maximum output capacitance is not explicitly stated in the datasheet, but as a general rule, Traco Power recommends limiting the output capacitance to 10uF to 22uF to ensure stable operation and minimize startup issues.
  • Yes, you can parallel multiple TRS2-1211 modules to increase the output current, but ensure that each module has its own input capacitor and that the modules are properly synchronized to prevent oscillations.
