10/11/2023Greetings, 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!
07/11/2023We’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!

14/08/2022Some 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!
01/07/2022Dear Customers, while we are working hard to complete your orders, preparing new material for our website (datasheets and product range updates) and preparing to present our new successfully completed projects – we still need to rest a bit too!
Public holidays are coming next week and so we would like to inform you that we will be unavailable from Monday to Wednesday (04.07 to 06.07). Have a nice day!
02/06/2022Dear Customers, our website is being updated. So far we have updated our Product range and Catalogue. Further in line are datasheets, new product series JETDiR-SP and supporting documents. Soon we will be posting more detailed information. Thank you for patience and wish you a splendid day!
14/03/2022JETDiR series datasheets have been all updated! From 20 W to 1500 W in “brick” form-factors within our most recent and widest temperature range, -60 °C to +125 °C of case temperature. Increased power outputs (incl. new R2B case):
case R2B – 40 W (new 1/16 BRICK)
case R3 – 100 W (previously 60 W)
case R4 – 150 W (previously 120 W)
case R5 – 300 W (previously 250 W)
case R6 – 700 W (previously 600 W)
case R6E – 1500 W
03/03/2022We are deeply sorry for what is happening in Ukraine for it brings loss to lives of many people, economics and endangers peace all over the world. We pray for the war to stop as soon as possible!
12/02/2022Dear Customers of our DC/DC series – TESND! In situation of risings costs of metals, ceramics and semiconductors (which pushes us to increase our pricing too) we chose the path of also increasing our units power characteristics. Please see our Selection guide for details. And also please enjoy our freshest TESND datasheets. We hope you’ll like it!
Based on burn-in testing we changed TESND series power values while keeping form-factors and pin-outs of our units! And so, the series now provides new increased power values:
case F2 – 50 W (previously 40 W)
case F3 – 100 W (previously 60 W)
case F4 – 150 W (previously 120 W)
case F5 – 300 W (previously 250 W)
case F6 – 600 W (previously 500 W)
case F7 – 1200 W (previously 1000 W)
TESND50-F3 now offers up to 3 galvanically isolated channels. But that’s not all. Due to our technological advancement our TESND units now operate in case temp operating range of -60 °C to +125 °C, without power derating!
Of course, for serial projects we still support production of previous TESND generations!
