Efficiency is 86.5% typical, and the unit is fully fanless with free-air convection cooling inside a slim 99 × 97 × 30 mm metal mesh case. Built-in short circuit, overload (hiccup mode, auto-recovery), and over voltage protection safeguard the load. It operates from -30°C to +70°C with derating, withstands 300V AC surge for 5 seconds, passes 5G vibration tests, and includes a power-on LED. Backed by Mean Well’s 3-year warranty, the LRS-75-5 offers high current 5V power in a low-cost, space-saving industrial package.
5V 14A / 70W Output: Strong 5V rail for logic boards, LED strips, relay/sensor banks, and embedded controllers.
Universal Input, No Switch: 85–264V AC / 120–373V DC, global-site ready.
1U Fanless Design: 99×97×30mm, metal mesh case, free-air convection, silent and maintenance-free.
Core Industrial Protections: Short circuit, overload (110–150%, hiccup/auto-recover), over voltage (5.75–6.75V).
Rugged & Certified: -30°C ~ +70°C, 300V AC surge 5s, 5G vibration, power-on LED, UL/TÜV/CE/CCC/EN62368-class, 3-year warranty.
