WRA1209S-3WR2 Frequently Asked Questions (FAQs)

  • MORNSUN recommends a PCB layout with a large copper area connected to the GND pin to dissipate heat effectively. A minimum of 1 oz copper thickness is recommended.
  • Yes, the WRA1209S-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 screwing procedures to ensure reliability.
  • To ensure EMC, MORNSUN recommends using a metal enclosure, keeping the module away from high-frequency components, and using proper filtering and shielding techniques.
  • The maximum output capacitance is 220uF. Exceeding this value may affect the module's stability and performance.
  • The WRA1209S-3WR2 is designed to operate up to 5000m altitude. However, the module's performance may degrade at higher altitudes due to lower air pressure and oxygen levels.
