Tips

• 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.
