Product Overview
The MEAN WELL LRS-350-24 is a 350 W enclosed switching power supply delivering a regulated 24 V DC at up to 14.6 A. Part of MEAN WELL’s LRS series, it uses a slim 30 mm high metal case (215 x 115 x 30 mm) and accepts 90-132 V AC or 180-264 V AC selected by a 115/230 V switch, as well as 240-370 V DC, with a typical efficiency of 88%.
The output can be trimmed between 21.6 V and 28.8 V, and the unit is protected against overload, overvoltage and over-temperature with automatic recovery. A built-in fan with ON/OFF control, 5 G vibration resistance, -25 to +70 °C operating range and IEC/UL 62368-1 safety approval make the LRS-350-24 a dependable 24 V supply for control panels, LED systems, CNC machines and general industrial equipment.
