## Summary description

The MEAN WELL LRS-50-12 is a 50.4 W power supply unit with a metallic finish. It operates on an AC input voltage of 85 - 264 V and a frequency of 47 - 63 Hz. With a mean time between failures (MTBF) of 645,000 hours, this unit ensures reliability. Its passive cooling design and compact dimensions (82 mm x 99 mm x 30 mm) make it ideal for various applications.

## Long description

LRS-50 is a 50W single-output enclosed power supply with a low-profile 30 mm design. It accepts a universal input voltage range of 85–264 VAC and is available with output voltages of 3.3V, 5V, 12V, 15V, 24V, 36V and 48V. The metal mesh enclosure and high conversion efficiency enable reliable convection cooling without a fan over a wide ambient temperature range, while very low no-load power consumption supports compliance with common safety standards for end products.
Advantages
The LRS-50 series achieves up to 90% efficiency and operates from -30 °C to 70 °C under natural convection thanks to its metallic mesh case. It consumes less than 0.2 W in no-load condition and is designed to meet safety standards such as EN60335-1, EN61558-1/-2-16, UL60950-1 and GB4943. Its enclosed single-output design provides a compact, reliable solution for industrial applications.

How to use
Install the LRS-50 on a flat surface with sufficient airflow around the metallic mesh enclosure to ensure convection cooling. Connect the AC input within the specified 85–264 VAC range and select the model with the required rated output voltage. Observe correct polarity when wiring the DC output and follow grounding instructions included in the manufacturer documentation. Do not block ventilation openings and avoid use in environments outside the specified ambient temperature range.
Recommendations
For reliable long-term operation, mount with at least a few centimeters of clearance on all sides for airflow, protect the unit against excessive dust and moisture per the appliance environment requirements, and choose the output voltage variant that matches the load requirements to maintain efficiency and compliance with safety standards.
