Fanless natural convection cooling reaches 88% typical efficiency with <0.3W no-load consumption. Built-in protections cover short circuit, overload (hiccup auto-recovery) and over voltage (13.8–16.2V, shutdown + re-power); the unit runs -30°C to +70°C with derating above 50°C and passes 5G vibration testing. It powers one 5m roll of standard 9.6W/m 12V RGB tape, or ~3m of 14.4W/m 12V RGB, or short runs of SK6812/WS2811 digital strips. Ideal for 12V LED installations, CCTV cameras, routers, access control, sensors and industrial control gear. For 24/7 operation de-rate to 85% load (≈42.8W / 3.57A). Not waterproof—mount indoors or inside a ventilated enclosure.
50W 12V Supply: 12V DC, 4.2A, 50.4W; output trims 10.2–13.8V via onboard pot for cable-drop compensation.
Worldwide AC Input: 85–264VAC / 120–373VDC, 47–63Hz; no region switch, survives 300VAC surge for 5s.
Fanless 1U Profile: 99×82×30mm, natural convection, 88% efficiency, power-on LED, 5G vibration, 3-year warranty.
Full Protection Suite: Short circuit (auto recovery), overload 110–150% (hiccup), over voltage 13.8–16.2V (shutdown + re-power); UL/TÜV/EN62368-1/EN60335/EN61558/CCC/CE.
12V Strip & Gear Ready: One 5m roll of 9.6W/m 12V RGB, ~3m of 14.4W/m 12V RGB, SK6812/WS2811 short runs, CCTV cam, router, sensor hub; pair with LRS-100-12 / LRS-150-12 for longer or denser 12V runs.
