Power Supply Unit MEAN WELL LRS-350-24 350.4 W Grey

The MEAN WELL LRS-350-24 is a compact industrial power supply delivering 350.4 W of continuous output power at 24 V DC. Designed for applications where reliable DC power is required, this unit accepts a wide AC input range and uses active cooling to maintain stable operation. Its grey metal enclosure and low-profile dimensions allow integration into control cabinets, automation equipment, and other installations with limited space.

Advantages

The power supply provides stable 24 V output with adequate current headroom for mid-range loads while maintaining efficient operation across the input range. Its active cooling enables sustained performance under load and in environments with moderate ambient temperatures. The metal housing offers mechanical protection and helps dissipate heat, and the compact footprint simplifies mounting in constrained spaces.

How to use

Install the power supply on a suitable flat surface or chassis using the mounting holes provided, ensuring adequate airflow around the fan intake and exhaust. Connect the AC mains input within the specified voltage range using properly rated wiring and secure terminals. Connect the 24 V DC output to the load, observing correct polarity. Verify earth/ground connection for safety and to reduce electrical noise. After wiring, power the unit and check output voltage and load behavior before finalising installation.

Recommendations

Place the unit in an environment with ventilation and ambient temperature within the manufacturer's recommended range. Avoid installing the supply near heat sources or in fully enclosed spaces without airflow. Periodically inspect the fan and connections for dust or looseness, and ensure the connected load does not exceed the rated output power to maintain long-term reliability.
