NVVV MDR-20-12 AC to DC DIN-Rail Power Supply 12V 1.67 Amp 20W vs Mean Well LRS-350-24 350.4W 24V 14.6 Amp Single Output Switchable Power

Overview of the Products

The NVVV MDR-20-12 and Mean Well LRS-350-24 are both efficient power supplies, but they cater to different power requirements and usage scenarios. The NVVV MDR-20-12 offers a lower output of 12V and 1.67 Amps, while the Mean Well LRS-350-24 delivers a much higher output of 24V and 14.6 Amps. Understanding these distinctions is crucial for choosing the right power supply for your needs.

Price Comparison

When comparing prices, the NVVV MDR-20-12 is significantly more affordable at C$21.41, whereas the Mean Well LRS-350-24 is priced at C$47.00. This difference of C$25.59 may reflect their varying capacities and target applications. Economically, if you are looking for a basic power supply that doesn’t require high output, the NVVV MDR-20-12 offers excellent value without compromising on performance for smaller projects.

Output Specifications

The NVVV MDR-20-12 provides a primary output voltage of 12V and a maximum power output of 20W, which makes it suitable for low-power applications. In contrast, the Mean Well LRS-350-24 has a much higher primary output voltage of 24V and a maximum output of 350W. This signifies that the Mean Well is designed for more demanding tasks, such as powering larger devices or multiple components simultaneously. If your project requires higher voltage and current, the Mean Well LRS-350-24 is unequivocally the better option.

Current Ratings

The current ratings of these power supplies showcase their capabilities. The NVVV MDR-20-12 has an output current of 1.67 Amps, while the Mean Well LRS-350-24 boasts an impressive output current of 14.6 Amps. This stark contrast indicates that the Mean Well is capable of handling significantly larger loads, making it ideal for applications that require more power. If your requirements include high current for motors or large circuit boards, the Mean Well will undoubtedly meet those needs.

Input Voltage Range

Both power supplies have different input voltage ranges that affect their versatility in various environments. The NVVV MDR-20-12 operates within an input voltage range of 85 to 264VAC, allowing it to function in diverse electrical conditions. However, the Mean Well LRS-350-24 is not specified in the provided data for input voltage, which typically aligns with industry standards, but this could limit its usability in certain situations. The NVVV’s wider range could provide more flexibility for users with varying power sources.

Build Quality and Design

While specific build quality details are not provided, both brands, NVVV and Mean Well, are recognized for their reliability in power supply manufacturing. The NVVV MDR-20-12 is designed for DIN-rail mounting, which is beneficial in organized electrical setups, ensuring easy installation and maintenance. On the other hand, the Mean Well LRS-350-24 is a switchable power supply, which often indicates a robust design that can handle different loads without significant stress. Users looking for durability and trusted performance will find both brands reputable, but the design may sway depending on the application.

Target Applications

The target applications for these two power supplies are distinctly different due to their specifications. The NVVV MDR-20-12 is appropriate for small-scale projects, such as powering sensors, LED strips, or low-voltage electronics. In contrast, the Mean Well LRS-350-24 is suited for industrial applications, powering larger machines, or multiple devices simultaneously, thanks to its high output capabilities. Understanding the intended use is crucial for selecting the appropriate power supply for your needs.

Which should you buy?

Ultimately, the choice between the NVVV MDR-20-12 and the Mean Well LRS-350-24 hinges on your specific power requirements. If you need a cost-effective solution for lower power applications, the NVVV MDR-20-12 at C$21.41 is an excellent choice. However, for projects demanding higher power, the Mean Well LRS-350-24 with its capacity of 350.4W and price of C$47.00 is the clear winner. Assessing your power needs will guide you in making the best decision tailored to your project.
