R-78K5.0-2.0 - RECOM Power

R-78K5.0-2.0 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  RECOM recommends a star-point connection for the input capacitors and a symmetrical layout for the output capacitors to minimize noise and ensure optimal performance.
• Can I use this module in a high-temperature environment?
  While the R-78K5.0-2.0 is rated for operation up to 85°C, it's recommended to derate the output current by 2.5% per degree above 60°C to ensure reliable operation in high-temperature environments.
• How do I ensure electromagnetic compatibility (EMC) with this module?
  To ensure EMC, RECOM recommends using a metal enclosure, keeping the input and output cables as short as possible, and using a common-mode choke or ferrite bead on the input lines.
• What is the typical efficiency of this module?
  The typical efficiency of the R-78K5.0-2.0 is around 95% at full load, but this can vary depending on the input voltage, output current, and operating temperature.
• Can I parallel multiple modules to increase the output current?
  Yes, multiple R-78K5.0-2.0 modules can be paralleled to increase the output current, but it's essential to ensure that the modules are identical and that the output voltages are matched to within 1% to prevent current imbalance.
