75W Mean Well Single Output Switching Power Supply LRS-75 Series

The Mean Well LRS-75 Series is a 75W Single Output Switching Power Supply designed for industrial automation, electrical equipment, electronic instruments, and control systems. Featuring a compact, low-profile design, the series operates from 85–264VAC and offers six rated DC output voltages ranging from 5V to 48V, with efficiency up to 91.5%.

Constructed with a durable metallic mesh enclosure and 30mm low-profile design, the LRS-75 features fanless cooling through free-air convection, low no-load power consumption, and comprehensive circuit protection. Designed for reliable operation in demanding environments, the series supports operating temperatures from -30°C to +70°C, subject to derating, withstands 5G vibration, and includes an LED power indicator. The LRS-75 is backed by a 3-year manufacturer warranty.
