MW LRS-35-12 12V 36W power supply

Mean Well LRS-35-12 power supply for 12 V systems

The LRS-35-12 is a compact single-output switching power supply intended to be built into final equipment. It delivers 12 V DC at up to 3 A, with a 36 W rated output. This makes it a practical component for a correctly designed low-voltage installation, electronic control equipment or a 12 V LED project that needs a mains-powered supply rather than a plug-in adaptor.

Verified electrical data

• 12 V DC output, up to 3 A;
• 36 W rated power;
• 85–264 V AC input, 47–63 Hz;
• 99 × 82 × 30 mm housing;
• operating ambient temperature from -30 to +70°C.

Compact enclosure, deliberate installation

Its 30 mm low-profile metal mesh enclosure is designed for heat dissipation by free-air convection. The manufacturer specifies this unit as a component for installation in final equipment, not as a standalone luminaire or a ready-made outdoor supply. The enclosure, clearances, cabling and compliance of the finished installation therefore need to be considered by a suitably qualified installer or designer.

Choose it by load, not by name alone

Add the demand of every connected 12 V DC receiver before selecting the power supply and keep it within the 36 W / 3 A limit. Check output polarity and follow the manufacturer’s installation instructions. The LRS-35-12 includes short-circuit, overload and over-voltage protection, but those features complement rather than replace proper circuit design. It is a focused choice when the required voltage, load and mounting conditions have all been confirmed.
