WRB2403S-3WR2 - Mornsun Power

WRB2403S-3WR2 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  MORNSUN recommends a PCB layout with a large copper area connected to the GND pin for heat dissipation. A minimum of 1 oz copper thickness is recommended, and the copper area should be as close to the module as possible.
• Can I use the WRB2403S-3WR2 in a high-vibration environment?
  Yes, the WRB2403S-3WR2 is designed to withstand vibrations up to 10G (10-2000Hz) and shocks up to 50G (11ms). However, it's recommended to follow proper mounting and screw torque guidelines to ensure reliable operation.
• How do I ensure electromagnetic compatibility (EMC) with the WRB2403S-3WR2?
  To ensure EMC, MORNSUN recommends following proper PCB design and layout guidelines, using a metal enclosure, and adding EMI filters or shielding if necessary. Additionally, the module should be placed at least 10mm away from other components to minimize electromagnetic interference.
• What is the maximum allowable capacitance for the output filter capacitor?
  The maximum allowable capacitance for the output filter capacitor is 47uF. Exceeding this value may cause instability or oscillation in the output voltage.
• Can I use the WRB2403S-3WR2 in a humid or high-temperature environment?
  The WRB2403S-3WR2 is designed to operate in environments with a relative humidity of up to 95% and temperatures ranging from -40°C to 85°C. However, it's recommended to follow proper derating guidelines for high-temperature operation and to ensure good airflow to prevent moisture accumulation.
