MEAN WELL SKMW40/DKMW40 Series

Size constraints continue to be a challenge across industries, from medical applications to industrial robots. MEAN WELL had previously rolled out its 1” x 1” wide input range DC-DC converters with power supply wattage ranging from 6W to 30W. Now, we’re excited to unveil the latest interaction for higher-wattage use cases: the SKMW40/DKMW40 Series!

These 40W single-output and dual-output converters are small in size but big on reliable power delivery. They feature a 4:1 ultra-wide input range and a variety of protections for even the harshest environments. They’re among the most durable power solutions currently available.

Here at Bravo Electro, we’re proud to be known as a leading MEAN WELL power supply distributor. Learn more about the SKMW40 and DKMW40 Series below, or get in touch to talk with an expert one-on-one for a more personalized overview of how this series can enhance your operation!

What is the MEAN WELL SKMW40/DKMW40 Series?

The MEAN WELL SKMW40 and DKMW40 series are 40W isolated DC/DC converters developed for a wide range of industrial, telecommunications, and transportation applications.

They fall under the broader umbrella of MEAN WELL’s lineup of compact power solutions aimed at delivering consistent, reliable power in as small a footprint as possible with a standardized 1” x 1” form factor. 

The SKMW40 series provides single-output functionality, while the DKMW40 series supports dual-output configurations for more diverse system requirements. However you use them, though, you can rest assured you’re getting the cutting edge of power delivery. 

Key Benefits and Features of the SKMW40/DKMW40 Series From MEAN WELL

There’s a lot to be excited about in the new SKMW40/DKMW40 Series from MEAN beyond its wide input range and compact footprint. Let’s take a look at all the features you’ll gain access to:

Compact Design for Space-Constrained Applications

The standardized 1” x 1” package is perfect for systems where space is a premium you can’t afford to waste - as is becoming the norm across all applications. 

Even the densest equipment layouts can accommodate the integration of the SKMW40/DKMW40 Series without compromising performance.  

Ultra-Wide Input Range and Output Flexibility

With a 4:1 input voltage range (9–36VDC or 18–75VDC), these converters align with a broad spectrum of input conditions. They’re adaptable to so many power sources.

But, MEAN WELL took this a step further with adjustable output voltage providing even more flexibility for users to fine-tune the output to meet specific system requirements.

Durability and Protection Features

We said already these are among the most durable, reliable converters on the market. You’ll enjoy a long power supply lifespan without stressing about bad power supply symptoms.

Protections include overload, overvoltage, input undervoltage, and thermal events. MEAN WELL has even equipped these converters with silicone gel potting for enhanced resistance to dust, moisture, and vibration. 

Temperature and Efficiency Performance

Whether your operation faces scorching heat or freezing cold, the MEAN WELL SKMW40/DKMW40 Series will continue to work reliably, rated for -40°C to +80°C. 

The converters rely on free-air convection cooling, which minimizes the need for additional thermal management systems while maintaining optimal energy efficiency. 

Speaking of power supply efficiency ratings, the series ranges from 86% all the way up to an impressive 91% to keep operating costs as low as possible. 

Certifications and Global Compatibility

From a power supply certification, MEAN WELL took measures to ensure these converters align with global safety and quality power supply standards. That includes UL, EAC, CE, and UKCA approvals. They also comply to BS EN/EN55032 Class A/B with additional components.

This simplifies regulatory compliance so you can rest assured the converters are compatible with international markets - especially if you’re building and selling equipment with these converters.

Best Applications for the SKMW40 and DKMW40 DC-DC Converters

There are so many use cases for the MEAN WELL SKMW40 and DKMW40 DC-DC converters, but a few in particular stand out as the most compelling applications. 

Telecommunication and Datacom Equipment

It’s no secret that consistent, reliable power delivery is a non-negotiable in telecommunication and data communication systems. That’s why the SKMW40 and DKMW40 series are a perfect choice.

Their ultra-wide input range integrates seamlessly with diverse power sources in telecom base stations, routers, and switches. Meanwhile, their compact size utilizes space as efficiently as possible in crowded racks. 

The high input-output isolation (2000VDC) protects sensitive communication circuits from electrical disturbances for peace of mind, too.

Industrial Automation and Control Systems

Industrial environments need robust and efficient power solutions for uninterrupted control systems and automated machinery operation. We’re already seeing strides made in using the SKMW40/DKMW40 for PLCs, motor controllers, and robotic systems.

The reason this is such a match made in heaven is the protections the SKMW40/DKMW40 series offers against dust, vibration, and wide temperature fluctuations - common challenges in these scenarios. 

Transportation and Energy Storage Applications

Railway signaling, electric vehicles, and energy storage setups like battery management systems all face similar hurdles in handling voltage fluctuations. This is no issue for the MEAN WELL SKMW40 and DKMW40 DC converters.

In fact, they’re designed to accommodate these with ease thanks to their wide input range. They’re built to provide a long, useful life in these applications with durable silicone potting for resistance to moisture and vibration.

Specialized Instruments and Devices

Precision instruments and specialized devices used in fields like medical diagnostics, laboratory research, and testing equipment need stable and noise-free power. 

Reliability is of the utmost importance in these for obvious reasons, too. You can feel confident powering yours with the SKMW40/DKMW40 series from MEAN WELL since it delivers consistent voltage regulation and minimal electromagnetic interference (EMI).

Its small form factor allows it to fit seamlessly into compact instruments without sacrificing performance, too. 

Choosing Between the SKMW40 Single Output DC Converter and DKMW40 Dual Output DC Converter

You can likely see why businesses are eager to upgrade their systems and power their operations using the MEAN WELL SKMW40 Single Output DC Converter or the DKMW40 Dual Output DC Converter. The only question is, what power supply do I need

They’re fairly similar in that each has the same 1” x 1” footprint and key features like a 4:1 ultra-wide input range, high efficiency of up to 91%, and robust protection mechanisms. It just comes down to understanding the nuances between single-output vs dual-output. 

The SKMW40 series is designed for applications requiring a single, steady output voltage. In this sense, it’s ideal for systems with straightforward power needs. 

On the other hand, the dual-output capability of the DKMW40 series makes it better suited for devices or systems that demand separate voltage rails. This essentially bypasses the need for multiple converters.

If you’re still on the fence, we’ll highlight a few of the most relevant specs for each of these converters below. Remember, though, Bravo Electro is your trusted choice for all things MEAN WELL - you can get in touch with us for a personalized recommendation!
