DC-DC Power Converters

DC-DC power converters are an essential intermediary for use between systems with different voltage levels. With the correct DC-DC power converter, you'll be able to convert a source of direct current (also known as a DC) from one voltage level to another.

We stock a great range of DC-DC power converters from popular manufacturers such as TRACO Power, XP Power, and Bel Power Solutions. There are excellent options from our own brand, RS Pro, too.

Browse the full range of DC-DC power converters below and use the advanced filters to speed up your search. You can narrow your search results according to the manufacturer, output voltage, output power, and more.

You'll find DC-DC converters in all different voltages and wattages when you browse our store online. Looking for a DC-DC converter with an output voltage of 12V? We've got those. Looking for a 24V DC-DC power converter? We've got those too!

You'll also be able to filter between single and double-output DC-DC converters. If we haven't got the product you need in stock, we can backorder for you.

What are DC-DC power converters?

A DC-DC power converter increases or decreases a voltage level, whenever it is required to protect the electronics within a device. They are often used in devices that are powered by a battery, rather than an external power source. This makes them popular for use with small, portable devices.

For example, a vehicle needs DC-DC conversion to make its radio safe to use. A DC-DC power converter's job, in this instance, is to take power from the vehicle's battery and make the radio safe to use by converting the power to a lower voltage.

A DC-DC converter does this by passing the power current through a "switching element". It turns the signal into a square wave, which briefly becomes AC. This wave is then passed through another filter, converting it back into a DC signal, which now has the appropriate voltage level for its new purpose.

What DC-DC power converters and other products are available?

When choosing the right DC-DC converter, there are various options to choose from. These are some of them that you'll find in our store:

Isolated DC-DC converter

An isolated DC-DC converter works well if you need a solution that offers protection for particularly high electrical voltages. It also tends to be quieter than a non-isolated converter because it can block noise and interference.

If you are looking for a high-current DC-DC converter, an isolated converter is a good choice. Unlike an non-isolated converter, there is a separation between the input and output terminals, and they are usually a safer option.

Industrial DC-DC converter

If you're looking for industrial-grade DC-DC power converters, you're in luck. We stock DC-DC power converters up to 3050W. You'll notice a great choice of output voltages as well, including a huge range of 24VDC power converters.

DC-DC voltage regulator

You can also find a variety of DC-DC voltage regulators in our store. Unlike a convertor, which alters the voltage, regulators ensure a consistent voltage is maintained, despite changes to load conditions or input. This is where DC-DC voltage regulators come in.

What are the benefits of using DC-DC power converters?

There are distinct benefits to using DC-DC power converters. These include:

• They are an effective way to reduce or boost voltage.
• They are available as whole hybrid circuit elements and don't require many additional components.

What should you consider when choosing your DC-DC power converter?

If this is your first time purchasing a DC-DC power converter, you may want guidance in choosing the right one. You will need to think about the following factors:

Output voltage

One important thing to consider when selecting a DC-DC power converter is the output voltage. Some converters allow you to adjust this using external resistors, but often the output voltage is fixed. Make sure that the DC-DC power converter you buy is capable of the load you require it for.

The output voltage, along with the output current, defines the electrical power that your converter offers.

Isolated vs non-isolated

You will also need to decide whether to use an isolated or non-isolated converter for your purposes. Non-isolated converters can sometimes be used for low-power devices, as they are smaller in size and highly efficient. They have a single circuit and are commonly used in the computer, automotive, and communications industries.

An isolated DC-DC converter separates the input and output (usually with a transformer). This increases safety, making it the design of choice for high-voltage DC-DC converters. This is usually the best option for industrial uses.
