MEAN WELL LRS-50 Power Supply

LRS-50 Power Supply Overview

The LRS-50 Power Supply from MEAN WELL provides stable and efficient 24V DC power for industrial equipment, control panels, automation systems and compatible low-voltage devices. The LRS-50-24 model delivers up to 2.2A rated current and 52.8W output power, making it a practical solution for compact electrical installations.

Moreover, the power supply accepts a wide input range of 85–264V AC or 120–373V DC. Therefore, installers can use it across different electrical networks without manually changing the input-voltage setting.

Compact Low-Profile Construction

The LRS-50-24 measures approximately 99 × 82 × 30mm. As a result, it fits easily inside machinery, electrical cabinets, equipment housings and compact control panels.

In addition, the ventilated metal enclosure supports effective heat dissipation. The unit uses natural air convection instead of a cooling fan. Consequently, it operates quietly and contains no fan that requires regular maintenance.

However, the enclosure is not waterproof. Installers should place the power supply inside a suitable protected cabinet and keep it away from water, excessive dust and accidental contact.

Efficient 24V DC Output

The LRS-50 Power Supply provides a regulated 24V DC output with up to 88% typical efficiency. This efficient operation helps reduce energy loss and unnecessary heat during continuous use.

Furthermore, installers can adjust the output voltage within the permitted range by using the built-in adjustment control. This feature helps compensate for minor voltage drops or match the output to compatible equipment. Nevertheless, the final voltage must remain within the connected device’s approved operating range.

Built-In Electrical Protection

MEAN WELL equips the LRS-50 series with protection against:

• Short circuits
• Overload conditions
• Overvoltage
• Excessive output demand

These protection functions help safeguard the power supply and connected equipment during abnormal operating conditions. For example, the short-circuit protection function uses hiccup-mode operation and automatically recovers after the installer removes the fault.

Recommended Applications

The LRS-50-24 supports a wide range of professional applications, including:

• Industrial automation equipment
• Electrical control systems
• Mechanical and electrical machinery
• Electronic instruments
• Security and access-control systems
• Display and signage equipment
• Monitoring devices
• Compatible 24V LED systems
• Low-voltage commercial equipment

Because this product is a general-purpose switching power supply rather than a sealed LED driver, installers must provide a suitable enclosure when using it in lighting applications.

Installation Guidelines

First, confirm that the connected equipment requires a 24V DC supply. Next, calculate the total current and wattage of the connected load. The system must remain within the rated 2.2A and 52.8W limits.

Then, connect the AC live, neutral and protective-earth terminals according to the markings. After that, connect the positive and negative DC outputs with the correct polarity.

Finally, secure the unit firmly and maintain enough open space around the ventilated housing. Proper airflow, correct wiring and appropriate load selection will help the LRS-50 Power Supply deliver dependable long-term performance.
