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!

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”.
18/04/2021
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.
19/02/2021During 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.

31/12/2020Happy New Year, friends, brothers-developers, generous buyers! Very hard year of 2020 ends for year 2021 to begin. A new year of hope for health, new technologies in our lives. It was not for nothing that we tried to work in a remote access and took lessons on the Internet from the most successful and talented businessmen!
Best of luck to everyone! Best of luck!
Our team in Czech republic did a lot, in preparation for 2021. We significantly widened our portfolio and started with the most fearful – publishing information about new power supplies on our website. Very soon our datasheets and description will be updated and new series will see the light. Yes, it’s a lot of word – to predict future of the company a year ahead! Thanks to the Czech government, helping in the hard times, we’ve been motivated for technical and technologic feats during new products creation.
What’s new?
The flagships of our most complex products have been mastered for serial production. Developments of 2019-2020: new fanless planar 1-phase and 3-phase JETA3000-LP and JETNA5000-LP units, fully modernized TESAV (TESH) series (implemented synchronous rectification – which is very difficult to apply with substantial input mains voltage fluctuations).
In 2021 year we are presenting a new cosmic era for our products, being brought into serial production are the TESD “SPACE” units. Our developers from Russia, Voronezh took part in the development of the series (our company TE “Tesla Electric”).
In year 2021 you’ll see completely new DC/DC units series of JETDis and TESDs. We call them budgetary (“Low Cost”), however they may please you not only by their miniature dimensions and low price, but also by ultra-wide input range of “48W” 9-80 VDC. Here we had to forget about the virus and work hard.
“Small but daring”! This is for our newest developed series – AC/DC JETAs units for 60, 120, 300, 700 and 1200 W. They also belong to the “Low Cost” class and contain optimized amount of service functions, although for the first time, for a lower priced series, we also implemented synchronous rectification!
Please follow changes on our website in the new year of 2021!

Outer space is next!
Specially for Your AEPS-group team has been developing cosmic DC/DC series of power supplies called TESD “SPACE” (TESD-SP)! The series contains a broad range of units for output powers of 10 W, 20 W, 40 W, 80 W, 200 W, 300 W, 500 W and 1000 W for the input voltage range “27W” (15-50 VDC, 80 VDC 1s).
The basis used is the most popular AEPS-group series which during many years was being produced under the names MDM, MR, TESND, TESD. The units of newest series TESD “SPACE” completely preserved the dimensions and pin-outs of TESD series units.
Due to utilizing newer circuitry and special components we achieved significantly improved EMC characteristics and resilience to external acting factors. The TESD “SPACE” units use optocoupler-less feedback circuitry. Built-in input and output EMC filters notably reduce conductive interference. Distinctive feature of the series is very high efficiency for such types of the DC/DC converters of 90-94 %.
Minimal weight and maximal efficiency – factors allowing the TESD “SPACE” series to ideally fit commercial and special applications in conditions where there are high demands for reliability and resilience to external acting factors.
Very soon you’ll see the TESD “SPACE” units in the selection guide of 2021, and also a separate product section for TESD “SPACE” will be published on our website.
