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!

vicor brick dc to dc converter replacement power supply

High voltage DC/DC converters. Create and replace!


Some time ago we have announced our capabilities to produce high voltage input (and output) DC/DC converters in brick form-factors. While details about our JETDiR (300 W up to 1500 W) high-input-voltage units are still being decided – we have begun something similar.

Recently we have been receiving requests and questions whether we can provide pin-to-pin replacements (within same dimensions and same mounting footprint) for certain units. One of the requested replacements was for units of well-known converter producer – VICOR company. In particular their high voltage input Micro, Mini and Maxi families which offer Quarter, Half and Full brick formfactors.

We applied our JETDiR design principles and created pin-to-pin mount-to-mount units for input mains of 180-375 VDC and 250-425 VDC. Their preliminary datasheets can be found in custom VICOR replacement product section. We accept high-quantity short-lead-time orders for these and similar units!
