PSK-30D-48 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  CUI recommends a PCB layout with a large copper area connected to the module's thermal pad to dissipate heat efficiently. A minimum of 2 oz copper thickness is recommended, and the copper area should be at least 1 inch x 1 inch in size.
• Can I use the PSK-30D-48 in a high-vibration environment?
  Yes, the PSK-30D-48 is designed to withstand high-vibration environments. However, it's recommended to follow the recommended mounting and screw torque specifications to ensure the module remains securely attached to the PCB.
• What is the maximum allowable input voltage ripple for the PSK-30D-48?
  The maximum allowable input voltage ripple for the PSK-30D-48 is 10% of the nominal input voltage. Exceeding this limit may affect the module's performance and reliability.
• Can I use the PSK-30D-48 in a humid or wet environment?
  The PSK-30D-48 is designed to operate in a dry environment. While it's not recommended to use the module in a humid or wet environment, it can be used in environments with a relative humidity up to 80% non-condensing. However, it's essential to follow proper conformal coating and sealing procedures to protect the module from moisture.
• What is the recommended input fuse rating for the PSK-30D-48?
  CUI recommends using a fuse with a rating of 5A to 10A, depending on the specific application and input voltage. The fuse should be able to handle the maximum input current and provide adequate protection against overcurrent conditions.
