PSK-20D-24 Frequently Asked Questions (FAQs)

  • CUI recommends a PCB layout with a large copper area for heat dissipation, and a thermal management system with a heat sink and thermal interface material to keep the junction temperature below 125°C.
  • To ensure reliable startup and shutdown, CUI recommends a soft-start circuit to limit inrush current, and a shutdown circuit with a voltage supervisor to prevent voltage drops during power-down.
  • The PSK-20D-24 is designed to meet CISPR 22 Class B and FCC Part 15 Class B emissions standards. To minimize EMI and RFI, CUI recommends using a metal enclosure, proper cable shielding, and filtering components.
  • The PSK-20D-24 is rated for operation up to 5,000 meters (16,400 ft) and 40°C ambient temperature. For high-altitude or high-temperature applications, CUI recommends derating the output power and consulting with their application engineers.
  • The MTBF rating for the PSK-20D-24 is approximately 550,000 hours at 25°C, calculated according to MIL-HDBK-217F.
