Model Selection: Ensure you choose the LRS-75 model with the output voltage (5V, 12V, 15V, or 24V) required by your application.
Load Considerations: Account for the maximum power draw of your load, ensuring it doesn't exceed the rated power of the selected LRS-75 model (70-76.8W depending on voltage).
Derating: Refer to the datasheet's derating curve. Reduce the maximum load if operating at high ambient temperatures (above 50°C) or low AC input voltages (<100-120VAC).
Altitude: Derate the output power by 5°C per 1000m for operation above 2000m (6500ft).
Installation Clearance: Allow sufficient space around the unit for effective free air convection cooling. Do not obstruct the ventilation holes.
Grounding (FG): Connect the frame ground terminal securely to the system's earth ground for safety and optimal EMC performance.
Wiring: Use appropriate wire gauges for AC input (L, N) and DC output (+V, -V) based on the current ratings. Double-check DC output polarity.
System EMC: The LRS-75 is designed as a component. The final equipment incorporating it must be re-verified for EMC compliance. Consult Mean Well's EMI testing guide for assistance.
