In critical situations and under challenging conditions, specialized devices, particularly tethered drones, may face external forces that could compromise their structural integrity and connections. In such circumstances, it is crucial for the device operator to swiftly resolve these issues on-site. Considering the potential for human error during the process of restoring the device’s functionality, even the simplest mistakes, such as mixing up the contacts, can occur.

As conscientious developers who prioritize the ongoing performance of our products, we have taken steps to support our end users. What does this mean? We have enhanced our JETDiV series modules by implementing polarity reversal protection. Whether you accidentally connect the positive and negative terminals in the wrong way (though we hope you avoid such errors), our module will operate correctly, ensuring reliability in extreme conditions and contributing to the success of critical missions.

This new feature has successfully completed all tests and trials, and we are now actively accepting orders!

Custom power solutions


Greetings, dear friends!

It’s no secret that our specialty is custom individual development. Despite the success and demand for our standard serial products, more and more often we get our hands on projects that require a non-trivial approach. For each such project, we craft distinct solutions, putting all our accumulated experience into them, combining it with state-of-the-art power supply technology.

Just look at how our new designs are replacing old ones and saving space through miniaturization!

DC DC extreme low temperature



We’re delighted to share some exciting news with you! Our DC/DC modules have successfully expanded their lower limit of the operating temperature range, now reaching an impressive -70 degrees Celsius. This significant enhancement applies to the JETDi, JETDiR, and JETDiV series.

But what does this mean for you? As you may be aware, our modules are utilized in devices and systems that operate in a variety of critical environments, including both manned and unmanned vehicles that carry out missions at altitudes of up to 40 kilometers. On average, for every 100 meters of altitude gain, the air temperature decreases by 0.6 degrees Celsius, or 6 degrees per kilometer, a phenomenon referred to as the vertical temperature gradient.

In essence, our modules are now capable of functioning at altitudes up to the Karman Line, which extends to approximately 100 kilometers. So, if you happen to have applications such as fighter jets, drones, weather probes, or any other devices conducting missions at altitudes nearing the edge of space, we strongly recommend using our power modules for the utmost reliability in your systems!

At IDET-23, a high-profile exhibition we participated, we observed a prominent trend: more than half of the companies on display were involved in the contemporary and forward-thinking field of aerospace. Rest assured, we too are making strides in this domain. Our JETDiR-SP series, a unique and novel creation, stands as a testament to our progress in this sector. As of now, this product is available in its prototype version! With this innovative module, our aim has been to curtail the need for exterior filter networks by incorporating a portion of these filters internally.

To browse our latest offerings, we invite you to peruse our catalogue. Bear in mind that the corresponding datasheets are currently being developed!



The offerings from our company experienced remarkable success at IDET-23, surpassing other cutting-edge innovations presented by Czech and international companies endorsing revolutionary electronics. Howevere the progress witnessed in the Czech high-tech industry for demanding applications left an indelible impression on us.

Without further ado, let us invite you to explore our captivating photoreport!

Advanced Power Supply Units for UAVs


Unmanned aerial vehicle (UAV) technologies are currently in high demand and are attracting the attention. We have been following this promising field for a long time.

As a result we has made a unified power units series called JETDiV, which comes in ultra-low profile shock- and vibro-resistance cases with reinforced mounting holes, designed for use on hardware PCBs.

We have prepared a handy mini-catalogue for you, available at this link, where you can find more information!
