With typical efficiency of 88%, fanless free-air convection cooling, and a slim 129 × 97 × 30 mm metal case, it fits easily into 1U racks and space-limited enclosures. Built-in protections for short circuit, overload, and over voltage help safeguard connected equipment. The unit also withstands 300V AC surge for 5 seconds, operates from -30°C to +70°C, passes 5G vibration testing, and includes a power-on LED. Backed by Mean Well quality and a 3-year warranty, the LRS-100-12 is an ideal balance of power density, safety, and cost-effectiveness.
12V 8.5A / 102W Output: Strong capacity for LED lighting, controllers, relays, and small automation systems.
Universal Input & 300V Surge Tolerance: 85–264V AC / 120–373V DC, with 5-second surge immunity for unstable grids.
Slim Fanless Design: Only 30mm profile, natural convection cooling, silent operation, lower maintenance.
Full Protection Suite: Short circuit, overload (hiccup mode, auto-recover), and over voltage protection built in.
Industrial Reliability: -30°C to +70°C operation, 5G vibration resistance, power-on LED, <0.3W no-load loss, 3-year warranty.
