URAM2CN1 - VICOR

URAM2CN1 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Vicor recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure good thermal conductivity. Additionally, keeping the PCB as thin as possible and using a high-thermal-conductivity material can help to reduce thermal resistance.
• How do I ensure reliable operation in high-vibration environments?
  To ensure reliable operation in high-vibration environments, Vicor recommends using a secure mounting method, such as screwing the module to the PCB or using a vibration-dampening material. Additionally, ensuring that the PCB is properly secured to the chassis and using a conformal coating can help to reduce the risk of vibration-induced failures.
• What are the limitations of the URAM2CN1's built-in EMI filtering?
  While the URAM2CN1 has built-in EMI filtering, it may not be sufficient for all applications. Vicor recommends that designers consider additional external EMI filtering components to ensure compliance with relevant EMI standards, especially in high-frequency or high-power applications.
• Can I use the URAM2CN1 in a redundant or N+1 configuration?
  Yes, the URAM2CN1 can be used in a redundant or N+1 configuration to ensure high availability and reliability. Vicor recommends using a diode-ORing or active-ORing scheme to ensure that the output voltage remains stable in the event of a failure.
• What is the recommended input capacitance for the URAM2CN1?
  Vicor recommends using a minimum of 10uF of input capacitance to ensure stable operation and to reduce the risk of input voltage ripple. However, the actual capacitance required may vary depending on the specific application and input voltage characteristics.
