RAC20-12SK Frequently Asked Questions (FAQs)

  • RECOM recommends a PCB layout with a large copper area for heat dissipation, and a minimum of 2oz copper thickness. A thermal via array under the module is also recommended.
  • Ensure a soft-start circuit is implemented to limit the inrush current during start-up. A recommended soft-start circuit is shown in the RECOM application note AN-102.
  • The maximum allowed capacitance on the output is 220uF. Exceeding this value may cause instability or oscillation.
  • Yes, the RAC20-12SK can be used in a redundant configuration, but it's essential to ensure proper ORing diodes and a suitable control circuit to prevent back-feeding.
  • The recommended input fuse rating is 2A slow-blow. This ensures protection against input overcurrent and overvoltage.
