RKZE-2405S - RECOM Power

RKZE-2405S Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  RECOM Power Inc recommends a PCB layout with a large copper area connected to the module's thermal pad to ensure good heat dissipation. A minimum of 2 oz copper thickness is recommended, and the copper area should be connected to a heat sink or a metal plate for further heat dissipation.
• How do I ensure the module's reliability in high-temperature environments?
  To ensure reliability in high-temperature environments, it is recommended to derate the module's output power according to the temperature derating curve provided in the datasheet. Additionally, ensure good airflow around the module, and consider using a heat sink or a fan to keep the temperature within the recommended operating range.
• What is the recommended input capacitor type and value for this module?
  RECOM Power Inc recommends using a low-ESR ceramic capacitor with a value of 10-22 μF, X7R or X5R dielectric, and a voltage rating of 50-100 V. The capacitor should be placed as close as possible to the module's input pins to minimize noise and ripple.
• Can I use this module in a redundant or parallel configuration?
  Yes, the RKZE-2405S can be used in a redundant or parallel configuration to achieve higher power output or redundancy. However, it is essential to ensure that the modules are synchronized and share the load equally to prevent overcurrent or overheating issues.
• What is the module's behavior during input voltage brownout or dropout?
  The RKZE-2405S has a built-in undervoltage lockout (UVLO) circuit that shuts down the module when the input voltage falls below 12 V. The module will automatically restart when the input voltage recovers to 12 V or higher.
