At a glance
Choose LRS-350-12 (12 V / 29 A) or LRS-350-24 (24 V / 14.6 A) — MEAN WELL delivers the power it states
Fine-tune for LED strip voltage drop or controller requirements (range depends on voltage variant)
Compact 215 × 115 × 30 mm enclosed chassis for tight enclosures
Switch-select AC input range for North American or international mains
Short circuit, overload, over-voltage, and over-temperature protection
Built-in DC fan with automatic ON/OFF control for quieter light loads
Before you wire it up
Set the 115 / 230 VAC selector switch to match your mains before applying power. Wrong setting can damage the supply. For LED installs, size wire for the current (up to 29 A on 12 V / 14.6 A on 24 V) and leave clear airflow around the fan exhaust.
