Testing of new power supplies based on JETA2000 prototype has been completed.
After optimization of circuit and design solutions, while keeping dimensions of 250x140x39 mm, maximal power was increased to 2500 W.
As a result, power density of new JETA2500 unit is 30 W/in3.
Both JETA2000 and its more powerful modification JETA2500 are now available to order.

Complete modernization of the popular TESD series with an output power of 10 to 500 W, supplied to support serial consumer production, has been completed.
New opportunities to create additional special functions are made possible by the use of optoelectronic devices with high resistance to ionizing radiation. In addition, it helps eliminate known shortcomings, such as low reliability of implementing isolating transformers in feedback circuits. However, a standard transformer-based feedback design is not excluded.
TESD units are designed in traditional reinforced cases with flanges that allow operation in conditions of strong vibrations and mechanical shocks.
Optimal for use in aplications 1, 2, 3, 4, 6, 11.

Modernizing the product series, we focused on the latest trends in power supplies design and the most modern components choice, thanks to which we managed to create even more low-profile units with high power density values:
JETNA1000-LP (1 000 W) – 28 mm profile, energy density 36 W/inch³
JETNA2000-LP (2,000 W) – 34 mm profile, energy density 39 W/inch³
JETNA3000-LP (3,000 W) – 36 mm profile, energy density 39 W/inch³
JETNA5000-LP (5,000 W) – 38 mm profile, energy density 42 W/inch³
The JETNA-LP series is ready for ordering and we hope that this new generation units will continue to help you in creating and building of compact and reliable power systems for challenging applications.

Upgraded series TESD/TESND


Dear colleagues!

We have upgraded DC/DC converters of the popular TESD series, which pin-to-pin replace other companies products well known in the Russian market.

We managed to significantly increase the efficiency of these modules (for some models up to 92%), while their price remained the same!

In addition, a new series of TESND modules with increased energy density has been developed and mastered, which, in comparison with TESD modules, will allow you to get the same output power in much smaller dimensions.
