MEAN WELL LRS-35 Power Supply

LRS-35 Power Supply Overview

The LRS-35 Power Supply from MEAN WELL provides reliable 24V DC power for industrial equipment, control systems, LED applications and electronic devices. The LRS-35-24 model delivers up to 1.5A and 36W, so it works well in compact installations that need stable low-voltage power.

Moreover, the unit accepts a wide input range of 85–264V AC or 120–373V DC. Therefore, installers can use it across different electrical networks without changing an input-voltage switch. Its compact design also makes installation easier inside control panels, machinery and protected equipment enclosures.

Compact and Efficient Performance

The power supply measures approximately 99 × 82 × 30mm. As a result, it requires minimal installation space and suits projects where enclosure dimensions are limited.

In addition, the 24V model reaches approximately 89% typical efficiency. This efficient operation helps reduce wasted energy and unnecessary heat. Furthermore, its no-load power consumption remains below 0.2W, which supports energy-conscious system design.

The power supply uses free-air convection instead of a cooling fan. Consequently, it operates quietly and contains fewer moving parts that may require maintenance. However, installers must leave enough open space around the ventilated enclosure to support proper airflow.

Reliable Electrical Protection

The LRS-35 Power Supply includes protection against short circuits, overload and overvoltage. For example, the overload function limits the effect of excessive current and allows the power supply to recover after the fault disappears.

Because the metal enclosure has ventilation openings, the unit does not provide waterproof protection. Therefore, installers should place it inside a suitable indoor enclosure or electrical cabinet. They should also protect it from moisture, dust buildup and accidental contact.

Suitable Applications

The MEAN WELL LRS-35-24 supports a wide range of low-voltage applications. For instance, contractors can use it for:

• Industrial automation equipment
• Access-control systems
• Security equipment
• LED lighting systems
• Electronic displays and signage
• Electrical control panels
• Mechanical equipment
• Monitoring instruments
• Small commercial machines

Additionally, the covered screw-terminal block allows straightforward input and output wiring. The installer can also use the built-in voltage-adjustment control to fine-tune the DC output within the permitted range.

Installation Guidelines

First, confirm that the connected equipment requires 24V DC. Next, calculate the total power and current demand. The connected load should remain below the power supply’s rated 36W capacity.

Then, connect the AC input, protective earth and DC output according to the terminal markings. Finally, secure the unit firmly and maintain enough ventilation around the enclosure. These steps help the LRS-35 Power Supply provide stable and dependable service.
