RAC10-12SK/277 Frequently Asked Questions (FAQs)

  • The recommended PCB layout for optimal thermal performance involves placing the module on a multi-layer PCB with a large copper area for heat dissipation. The copper area should be connected to a solid ground plane to ensure good heat conduction.
  • To ensure reliable start-up of the converter, make sure to provide a slow ramp-up of the input voltage (typically 10-20 ms) and ensure that the input voltage is within the specified range. Also, ensure that the output capacitors are properly sized to handle the inrush current.
  • The maximum allowed capacitance on the output is 2200 uF. Exceeding this value may cause instability or oscillations in the converter.
  • The RAC10-12SK/277 is rated for operation up to 80°C ambient temperature. However, derating may be necessary for high-temperature applications. Consult the datasheet for derating curves and consult with RECOM Power Inc for specific guidance.
  • To protect the converter from input voltage surges, consider adding a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit at the input. This will help absorb voltage spikes and ensure reliable operation.
