PRM48BH480T250A00 Frequently Asked Questions (FAQs)

  • Vicor recommends a 4-layer PCB with a solid ground plane, and thermal vias under the module to dissipate heat. A thermal interface material (TIM) should be used between the module and the heat sink.
  • To ensure reliable start-up and shutdown, Vicor recommends a soft-start circuit to limit inrush current, and a controlled shutdown sequence to prevent voltage spikes.
  • At high altitudes, the PRM's power rating may need to be derated due to lower air pressure and reduced heat transfer. Consult Vicor's application notes for altitude derating guidelines.
  • Yes, the PRM48BH480T250A00 can be used in redundant or parallel configurations, but Vicor recommends consulting their application notes for specific guidelines and considerations.
  • The PRM48BH480T250A00 is designed to meet CISPR 11 and CISPR 22 EMI standards. However, additional EMI filtering and shielding may be required depending on the specific application and environment.
