Dear 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!

Dear 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!

JETDiR 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 

We 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.

Dear 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!

Reviewed, corrected, updated. Our polished catalogue for AC/DC, DC/DC and AC-DC/DC products for harsh environment has been re-uploaded! Please find the catalogue under the same address here or via the menu (see Products section).

Dear Customers, the site is being updated. In particular, our product range, series parameters and datasheets contents. Some information presented on website at the moment may not be actual, however we’re working hard to finalize our updates as soon as possible and upload the updates to our website. If you have any questions, please ask.
Thank you!

Typical system with DC/DC converters involves application of additional EM filters to achieve compliance of MIL–STD–461. But in special cases – customers require converters that don’t need any external components.
Due to such requirements, we completed R’n’D allowing us to implement special filter circuitries inside the converters. This allows creating compact systems of distributed power delivery without placing any external EM filter components or other mandatory components, which are normally required for stable converter operation.
AEPS-group now offers new DC/DC converters JETDiR32-R (22x60x15 mm) and JETDiR70-R5 (61x59x13 mm). The JETDiR32-R is made for input voltage range “270” (230-350 VDC, 450 VDC transient) and JETDiR70-R5 for input voltage range of 135-245 VDC. Without any external components the units comply with MIL–STD–461 CE101 and CE102.
Preliminary datasheets for units JETDiR32-R and JETDiR70-R5 are located in section “DC/DC custom units and blocks”.

Logical continuation of JETDiR series in industrial case BRICK form-factors is a brand-new converter: JETDiR1500-R6E with output power of 1500 W. The new input range is introduced – “270” (230-350 VDC, 450 VDC transient). The converter utilizes “flexible” case of BRICK size (modified according to customers’ requests), with dimensions of 119х63х15 mm.
The emergence of the JETDiR1500 sets a unique (for us) top level of power density – 218 W/in3 with typical efficiency of 94 %. Until this moment, the highest power density belonged to our DC/DC converter – TESND1000 – 118 W/in3.
The converter was designed to power load based on GaAs and GaN devices, with typical output voltage of 30-60 VDC. First production batches will start in May 2021.
The final datasheet will soon appear next to the other standard JETDiR products in section of “DC/DC power supply units for critical applications”. At this moment, preliminary datasheet is available in the section “DC/DC custom units and blocks”.
Next is the manufacturing preparation a new model of JETDiR2000-R6E with output power of 2000 W.

During recent years we’ve completed a lot of very interesting projects for custom power supplies. New product groups have appeared – AC/DC custom units and blocks and DC/DC custom units and blocks. We will continue to add to these categories and display you our newest projects and capabilities. Keep up with the updates. We will be very glad if you find something to your liking.
