Pyramid Desktop Bench Power Supply vs MEAN WELL LRS-100-24 AC/DC Switching Power Supply 108W 24V 4.5A Single Output fo

Price Comparison

When comparing the prices of the Pyramid Desktop Bench Power Supply and the MEAN WELL LRS-100-24, there's a significant difference. The Pyramid power supply is priced at C$70.78, while the MEAN WELL model is considerably more affordable at C$32.95. This almost C$38 difference can be a deciding factor for budget-conscious buyers. The MEAN WELL offers a more cost-effective solution for those who seek a reliable power supply without needing advanced features. However, the higher price of the Pyramid power supply reflects its additional functionalities, which may justify the cost for specific applications.

Design and Build Quality

In terms of design, the Pyramid Desktop Bench Power Supply features a rugged housing construction suitable for benchtop or desktop placement. It includes a built-in cooling fan to prevent overheating during operation, which is crucial for maintaining consistent performance. On the other hand, the MEAN WELL LRS-100-24 has a compact profile of just 30mm, making it ideal for tight spaces. Its metal mesh housing promotes superior heat dissipation without the need for a fan, allowing it to operate quietly. While both power supplies boast durability, the Pyramid's cooling fan may appeal to users who require more robust thermal management.

Power Output and Efficiency

The Pyramid power supply provides a continuous current of up to 12 amps with a voltage output of 13.8V DC, making it suitable for various applications such as charging devices or testing equipment. In contrast, the MEAN WELL LRS-100-24 delivers 4.5 amps at 24V, with a total power output of 108W. Notably, the MEAN WELL unit achieves an impressive energy efficiency of 90%, minimising power loss during operation. While the Pyramid offers higher amperage, the MEAN WELL's efficiency and stable performance make it an attractive option for users focused on energy conservation and consistent output.

Features and Functionality

The Pyramid Desktop Bench Power Supply includes several user-friendly features, such as a USB charge port and universal screw connection terminals, providing versatility for various devices. It is designed with safety in mind, featuring built-in overload and short-circuit protection. Meanwhile, the MEAN WELL LRS-100-24 is designed for industrial and commercial applications, emphasizing stability and safety with full protection against overvoltage, overload, and short circuits. The choice between these two products depends on whether users prioritise versatility and ease of use (Pyramid) or industrial-grade reliability and efficiency (MEAN WELL).

Compatibility and Use Cases

The Pyramid power supply is well-suited for hobbyists and professionals alike who require a dependable power source for testing and powering devices such as cellular phones, radios, and scanners. Its plug-in operation allows for quick setup, making it ideal for temporary or bench testing scenarios. In contrast, the MEAN WELL LRS-100-24 is more suited for permanent installations in industrial and commercial settings, given its robust construction and ability to withstand high-altitude operation. Users must consider their specific needs when selecting between these two power supplies, as their intended applications differ significantly.

Safety Features

Safety is paramount in power supply design, and both products offer essential protection features. The Pyramid power supply is equipped with electronic overload and short-circuit protection, ensuring the safety of both the operator and connected electronics. Similarly, the MEAN WELL LRS-100-24 includes comprehensive safety mechanisms such as overvoltage protection, overload protection with automatic recovery, and short circuit protection. Both models adhere to safety standards, providing peace of mind for users. However, the more extensive testing and rugged construction of the MEAN WELL may appeal to those prioritising industrial safety standards.

Cooling Mechanism

The cooling mechanisms of these two power supplies differ significantly. The Pyramid Desktop Bench Power Supply includes a built-in cooling fan, which is crucial for maintaining optimal operating temperatures during extended use. This feature is particularly beneficial in scenarios where high current is drawn for prolonged periods. In contrast, the MEAN WELL LRS-100-24 utilises a fanless design with a metal mesh housing that facilitates heat dissipation without producing noise. This design is advantageous for environments where silence is essential, such as in laboratories or offices. Users must evaluate their environment and requirements when considering the importance of cooling mechanisms.

Which should you buy?

Choosing between the Pyramid Desktop Bench Power Supply and the MEAN WELL LRS-100-24 ultimately depends on the user's specific needs and preferences. If you require a versatile, user-friendly power supply for hobbyist applications or testing, the Pyramid's robust features and higher output may justify its higher price. Conversely, if you're seeking an efficient, reliable power supply for industrial use at a lower cost, the MEAN WELL LRS-100-24 offers excellent performance and safety without breaking the bank. Assess your application requirements, budget, and desired features to make the best decision for your power supply needs.
