Power Supply Unit MEAN WELL LRS-50-5

The MEAN WELL LRS-50-5 is a compact 50W enclosed AC-DC power supply with a universal AC input range of 85–264V. Designed as a single-output metallic unit, it delivers a stable +5Vsb output and meets RoHS requirements for environmental and safety compliance. Its small footprint (82 mm × 99 mm × 30 mm) makes it suitable for installation where space is limited.

Advantages

The LRS-50-5 offers a reliable single 5V standby output with up to 10A maximum current, a durable metal enclosure for improved heat dissipation and mechanical protection, and a wide input voltage range that supports international mains without additional converters. RoHS certification ensures reduced hazardous substances.

Suitable for

• Embedded systems and industrial control equipment
• Telecommunications and standby power applications
• Small servers, routers and networking devices requiring a 5V standby rail
• General electronic equipment requiring a compact sealed power module

How to use

Mount the LRS-50-5 in a location with adequate ventilation and secure it according to the device mounting recommendations. Connect the AC mains input within the specified 85–264 VAC range and observe correct polarity for the DC output connections. Verify output voltage and load current do not exceed the specified 5Vsb and 10A ratings. Follow applicable local electrical codes during installation.

Usage recommendations

For reliable long-term operation, allow sufficient clearance around the unit for airflow, avoid mounting in high-temperature or high-humidity environments, and use proper fusing on the AC input. Regularly inspect connections for corrosion or looseness, and ensure the load stays within the rated 50W output.
