<h4>Discover our new digital tool for support!</h4>
<p><strong>Are you tired of looking for documents and papers?</strong> Do you want a smooth and available solution to the problem?</p>
<p>With our customer portal you get access to the following functions:</p>
<ul>
<li>Information of your system</li>
<li>Tools for annual testing</li>
<li>Documentation</li>
<li>FAQ</li>
<li>Contact form to our support</li>
</ul>
<p>The most common documents you will find in the customer portal are manuals, layouts, circuit diagrams, device lists, single line diagrams, and setting lists.</p>
<p><strong>Do you want to connect?</strong></p>
<p>To get access to our customer portal with information about your system we have chosen to use QR codes that are placed on your system, and you can easily get access to relevant information.</p>
<p>Scan the QR code, create an account and confirm via e-mail and you will be up and running.</p>
<p>There are two levels for your account, basic and extended. If you chose basic, you will access every information besides documentation. This type of account you only confirm by yourself with your specified e-mail. If you choose an extended account, you will access everything that a basic account provides you with and documentation as well.  This type of account needs to be confirmed with your specified e-mail and from us at KraftPowercon. This is for your own safety.</p>
<p><strong>Do you have existing equipment from us but missing a QR code? </strong>Contact us via e-mail which you will find below, and we will help you get connected!</p>

Galvanically isolated DC/DC Converter for fuel cells | DCKraft

This scalable DC/DC converter has galvanic isolation between input and output which protect the fuel cell from dangerous electric disturbances.

<p>DCKraft is a new developed solution for customers who want to maximize the output from the Fuel Cell, with a compact design and highest possible reliability.</p>
<p>The DC/DC converter — DCKraft — has galvanic isolation between input and output which protect the Fuel Cell from dangerous electric disturbances and create a safe and simple scalability.</p>

Fuel Cell Adaptable

<p>The galvanically isolated converter plays a vital role in the seamless integration of Fuel Cells, primarily due to the high sensitivity of the Fuel cells to ground faults. Using an isolated DC/DC it protects the fuel cell from any ground faults that occur on the DC bus to which it is connected. The galvanic isolation serves as a protective barrier, preventing the direct flow of electrical current between the input and output sides. This isolation is achieved through the use of transformer-based techniques, which effectively break the electrical connection while allowing the transfer of power.</p>


<p>DCKraft will be delivered as a power module or integrated into a cabinet, completed factory tested. It will be coming with DNV type approval and CE marked. DCKraft has a basic visual interface with status LED’s. Setup and diagnostics can be performed with PC interface via USB to each PM.</p>


<p>By using tailormade components the DCKraft is design with a high focus on power density, both for the module but also the ability to incorporate up to four DCKraft into one cabinet with a total power of 800 kW. This is particularly advantageous in spaceconstrained applications where size and weight reduction are critical, which always is a matter in a marine context. By packing more power into a smaller space, high power density enables the design of smaller and lighter systems, leading to reduced installation.</p>


<p>By using top line of Silicon Carbide (SiC) technology the DCKraft module will come with a very high efficiency >97 %. One of the key advantages of SiC is its ability to handle higher voltages and current densities while minimizing power losses. As a result, SiC-based power electronics systems can deliver greater efficiency, and improved overall performance. The DCKraft can be optimized to the specific Fuel Cell brand to reach a peak efficiency at the operation level according the the typical Fuel Cell curve.</p>
