RK-2412S - RECOM Power

RK-2412S Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  RECOM recommends a PCB layout with a large copper area connected to the module's thermal pad, and a minimum of 2oz copper thickness. A thermal via array under the module can also improve heat dissipation.
• How do I ensure reliable start-up and operation with a high-capacitance output filter?
  To ensure reliable start-up and operation, RECOM recommends using a soft-start circuit or a ramp-up circuit to limit the inrush current. Additionally, a minimum output capacitance of 10uF is recommended, and the output filter should be designed to minimize the voltage overshoot during start-up.
• What is the maximum allowed input voltage deviation for reliable operation?
  While the datasheet specifies a recommended input voltage range, RECOM recommends keeping the input voltage deviation within ±10% of the nominal input voltage to ensure reliable operation and minimize the risk of damage or malfunction.
• How do I protect the module from input voltage transients and surges?
  RECOM recommends using a TVS (Transient Voltage Suppressor) diode or a varistor at the input to protect the module from voltage transients and surges. The TVS or varistor should be selected based on the expected transient voltage amplitude and duration.
• What is the recommended input fuse rating and type for overcurrent protection?
  RECOM recommends using a fuse with a rating of 2-3 times the maximum input current, and a fast-acting fuse type (e.g., ceramic fuse) to provide effective overcurrent protection. The fuse should be placed as close to the input as possible to minimize the risk of damage or malfunction.
