MEAN WELL LRS-100-24 AC/DC Switching Power Supply 108W 24V 4.5A Single Output fo vs Official Raspberry Pi 5 27W USB-C Power Supply

Overview of the MEAN WELL LRS-100-24 and Official Raspberry Pi 5 Power Supply

The MEAN WELL LRS-100-24 offers a robust 108W power supply solution, while the Official Raspberry Pi 5 provides 27W tailored for Raspberry Pi devices. Both power supplies cater to different needs in the power supply market, each with unique features suited for their respective applications.

The MEAN WELL LRS-100-24 is engineered for industrial and commercial uses, providing a stable 24V output at 4.5A. This makes it an excellent choice for applications requiring higher power. In contrast, the Official Raspberry Pi 5 Power Supply is specifically designed for the Raspberry Pi 5, offering multiple power delivery profiles for versatility but with a maximum output of 27W, which is significantly lower than the LRS-100-24.

Power Output and Capacity

When it comes to power output, the MEAN WELL LRS-100-24 significantly outshines the Official Raspberry Pi 5. The LRS-100-24 delivers a constant output of 24V at 4.5A, amounting to a total of 108W. This high output is suited for demanding applications, such as industrial automation and control panels.

In comparison, the Official Raspberry Pi 5 Power Supply provides a maximum output capacity of 27W, which is more than sufficient for powering the Raspberry Pi 5 and its peripherals but falls short for high-demand applications. It offers adjustable outputs of 5.1V at 5A and other profiles, but none can match the continuous output of the MEAN WELL unit.

Efficiency and Performance

The efficiency of a power supply is crucial for minimizing energy waste and ensuring reliable operation. The MEAN WELL LRS-100-24 boasts an impressive energy efficiency rating of 90%. This means that it effectively converts 90% of the input power into usable output, minimizing losses significantly.

On the other hand, while the efficiency of the Official Raspberry Pi 5 Power Supply is not explicitly stated, it is designed to provide stable power even under full loads. However, with a maximum output of 27W, the overall power management and efficiency may not be as critical as in high-efficiency applications, where the MEAN WELL excels.

Design and Build Quality

The design and build quality of a power supply can greatly impact its durability and usability in various environments. The MEAN WELL LRS-100-24 features a compact design with a slim 30mm profile and a metal mesh housing, allowing for superior heat dissipation. This rugged construction is designed to withstand high-altitude operations and ensures long-term reliability in industrial settings.

Conversely, the Official Raspberry Pi 5 Power Supply, while also well-built, is primarily intended for home and small-scale applications. It comes with a 1.2m USB Type-C cable, making it convenient for desktop setups but does not match the ruggedness or versatility of the MEAN WELL design, which is built for harsher environments.

Compatibility and Usability

The MEAN WELL LRS-100-24 is designed with a universal AC input voltage range of 85-264VAC, making it compatible with global power standards. This feature allows it to be used in various regions without concern for voltage differences, enhancing its usability in industrial applications.

In contrast, the Official Raspberry Pi 5 Power Supply is also designed for a wide input range of 100-240V AC, making it suitable for North American and international use. However, its specific output configurations are tailored to Raspberry Pi devices, limiting its usability in broader contexts compared to the versatile MEAN WELL power supply.

Safety Features

Safety is a critical aspect of any power supply, and both products incorporate essential safety features. The MEAN WELL LRS-100-24 includes full protection against overvoltage, overload, and short circuits, ensuring reliable operation even in fluctuating conditions. It has undergone 100% burn-in testing, which adds an extra layer of confidence in its performance under various environmental conditions.

The Official Raspberry Pi 5 Power Supply also includes built-in power profiles that help manage power delivery safely. However, it lacks the extensive safety certifications and protection features present in the MEAN WELL power supply, which is crucial for industrial applications where safety and reliability are paramount.

Pricing Comparison

Pricing is an essential factor when choosing between two power supplies. The MEAN WELL LRS-100-24 is priced at C$32.95, which reflects its higher output capacity and industrial-grade build. This price is reasonable considering the power and features offered.

The Official Raspberry Pi 5 Power Supply is slightly cheaper at C$31.90. While it is a cost-effective option for Raspberry Pi users, its lower output and application-specific design may not justify the price for those needing more power.

Which should you buy?

Choosing between the MEAN WELL LRS-100-24 and the Official Raspberry Pi 5 Power Supply ultimately depends on your specific needs. If you require a high-output power supply for industrial or commercial applications, the MEAN WELL LRS-100-24 is the clear winner, offering 108W of power, superior efficiency, and robust safety features.

However, if you are a Raspberry Pi 5 user looking for a reliable and purpose-built power supply for everyday use, the Official Raspberry Pi 5 Power Supply is a good choice, providing sufficient power for typical applications at a slightly lower price. In conclusion, assess your power requirements carefully to make the best choice for your situation.
