Meanwell LRS-50-12 SMPS

LRS-50-12: 50 Watt 12 Volt Meanwell SMPS

The Meanwell LRS-50-12 is a 50 Watt enclosed type SMPS designed for reliable and energy-efficient DC power delivery in a compact 1U low-profile form factor (30 mm height). Meanwell LRS-50-12 accepts universal AC input (85–264 VAC) or DC input (120–373 VDC) and delivers a regulated 12 Volt DC output at 4.2 Ampere. With high efficiency (up to 88%), a fanless design, and ultra-low no-load power consumption, it meets global energy-saving regulations such as ErP and DOE Level VI. A rugged metal mesh case improves thermal dissipation, enabling wide operating temperatures from –30°C to +70°C under free air convection.
