5V 40A power supply for LED display systems
The Mean Well LRS-200-5 provides a single 5V DC output rated at 40A and 200W. Its metal mesh enclosure uses free-air convection, making it suitable for installations where fanless cooling is preferred. Check the LED module voltage, total load and cabinet ventilation before selecting the supply.

Input selection and installation
Set the input selector to match the supply voltage before applying power. The two AC ranges are switch selected, so this model should not be treated as an automatically ranging input. Keep the mesh enclosure ventilated and apply the temperature derating requirements in the specification.
Protection functions cover short circuit, overload, overvoltage and overtemperature. The power-on LED provides a visual operating indicator.
