Fonte de alimentação fechada MEAN WELL LRS-35-5 35W 5V 7A

The MEAN WELL LRS-35-5 stands out in the 35-watt power supply class by combining a compact, perforated metal enclosure with a remarkably wide input voltage range of 85–264 VAC. Unlike many budget units that sacrifice efficiency or thermal headroom, this model delivers a stable 5 VDC output at up to 7 A while maintaining 83% efficiency and full operation from -20°C to 70°C under free air convection. Its low no-load power consumption and compliance with multiple international safety and EMC standards make it a future-proof choice for industrial, automation, and LED applications.

Highlights

In daily use

Thanks to its chassis-mount form factor and screw terminal connections, the LRS-35-5 integrates quickly into control cabinets, machinery, or LED lighting systems. The free air convection cooling means no fan noise or maintenance, and the wide temperature tolerance ensures reliable starts even in cold environments. The built-in protections safeguard both the power supply and connected loads, reducing downtime in demanding industrial settings.
