What is a DIN rail power supply, exactly?

If you're looking to learn about what this type of power supply is, whether or not you need one, and what to consider when sourcing one, you've come to the right place. We'll talk about all this and more today.

In short, a DIN rail power supply is simply an electrical component that can be used to stabilize an input voltage and turn it into a more functional output voltage for certain devices. It's used in a variety of industries - from mechanical engineering to automotive manufacturing, sustainable energy, and a whole lot more.

And here at Bravo Electro, we don't just have the premier selection of DIN rail power supplies - we have experts on staff to help you find the right brand, model, and specifications for your unique needs. Before we get into all that, though, allow us to unpack the basics of DIN rail power supplies in greater detail below.

What is a DIN Rail Power Supply?

So...what is a DIN rail power supply? We described it very briefly above, but we're going to take a deeper dive into the ins and outs of this power supply now.

At its core, a DIN rail power supply is what's known as an AC-DC converter. This means it takes in alternating current (AC) and converts it into direct current (DC). The output of a DIN rail power supply can be adjusted to provide the voltage you need depending on what particular device you're powering or what system you're designing.

These types of power supplies offer cost-saving benefits through their superior operating efficiency. They also produce less heat than other types - saving you money there as well. And because less heat is produced, smaller heat sinks are required. Thus, they take up less space.

Another benefit of the DIN rail style power supply is the ease of setup and use. You can get your equipment running in minutes with minimal tools needed. 

The key to attaining all the benefits DIN rail power supplies have to offer is choosing the right one. And we’ll guide you through that shortly. First - you may be wondering…why is it called DIN rail?

Why is it Called DIN Rail?

The name itself comes from what they look like - they are typically mounted on metal “DIN rails,” which are standard mounting systems used in industrial settings to securely hold the components in place.

They come with electrical connectors that make them very easy to install and use. But, this begs the question - what does DIN stand for in DIN rail?

What Does DIN Stand for in DIN Rail?

What does DIN stand for in DIN rail, exactly?

"DIN" is an acronym for "Deutsche Industrie Normen," which is German for "German Industrial Standards." DIN rails are simply a type of standardized mounting system used in industrial settings.

What is a Din Rail Power Supply Used For?

Now that we know what DIN rail power supplies actually are, what is a DIN rail power supply used for exactly?

Din rail power supplies tend to be used in industrial or laboratory settings and can power a range of devices, including motors, electric pumps, machine tools, process control systems, LED lighting fixtures, and more.

They can also be used in commercial environments like shops or warehouses where their robust construction makes them ideal for harsh conditions.

How Do I Choose the Right DIN Rail Power Supply?

As mentioned earlier, you cannot overlook the importance of choosing the right power supply. The best way to get set your setup optimized is to leverage the help of our experts at Bravo Electro. Just reach out and we’ll offer a personalized recommendation based on your unique needs.

Voltage, Amperage, & System Requirements

When you are looking for a DIN rail power supply, there are a lot of things to consider. But the first thing to think about is what the power supply will be used for. This will help determine what voltage and amperage you need. For example, if you need a power supply for an LED light fixture, you'll want one with a low voltage and amperage rating. 

Other considerations here include whether you need a 1-phase or 3-phase system. You should also consider whether or not you need your supply to be capable of running DC power at the output (learn more about how to convert DC to AC power in our blog).


Another thing to think about is what type of environment the power supply will be used in. If it will be in a dusty or wet environment, you'll want one that is rugged and waterproof. Other environmental factors to take note of are maximum and minimum temperatures. Finally, consider if vibrations will occur frequently on the rail. If so, the need for a rugged power supply is even greater. 

Size & Shape

You'll also want to consider the size and shape of the power supply. DIN rail power supplies come in a variety of sizes and shapes to fit into whatever space you have available.

Performance, Reliability & Ratings

In terms of performance, you’ll want a power supply that generates low heat - this contributes to greater efficiency, longer lifespan, and greater reliability.  

Different brands offer different heat-minimizing features and reliability ratings, so it's important to do your research before making a decision. We prefer MeanWell equipment as this manufacturer's reputation speaks for itself.

This is also a good time to consider any ratings you need related to the region or market - such as UL listing, class 2 vs class ii, and more. The last thing you want to do is get the wrong classification and end up with delays/setbacks - or worse, compliance issues.
