Good day, Dear friends!

Because of the heavy workload we did not notice how the four-digit number on our calendars has changed. Despite this, while a little late, we still would like to wish you happiness and peace of mind in your personal life and business in New Year from our heart.

Our construction has progressed forward in year 2023 and we’re confidently moving towards its completion. Hopefully, soon you’ll be able to visit us in our own new home. Same as every new year, we have something new in works that we’d be glad to share with you. We will soon update our product range, where you’ll find renewed JETDi, JETDiR, JETA-LP and JETNA-LP series power supply units and converters.

We appreciate your cooperation and value your trust in us!

Stay tuned for the latest news and updates! Thank you!

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!

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 

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!

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!

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.

On our website www.aeps-group.com you can find a new selection guide for year 2021. To be able to conveniently choose a product we provide classification of our units according to areas of application.
    1. Standard series units of „low cost“ class. In 2020 we have already started production of JETAs, JETDis, TESDs to fill our stock. The goal is to provide as fast as possible delivery time. They successfully replace units of previously produced generation TESA, JETA and, in some cases, they can replace popular, but more expensive JETA-LP, as well as JETDi, TESD, TESND series. We are sure that you will be pleased with the ability of new JETDis, TESDs to operate with input voltage range of 9-80 VDC (100 VDC transient).
    2. A group of AC/DC and DC/DC units for critical missions (maximum power, planar design, ultra- wide temperature ranges on request with maximum of service functions) – JETA-LP, JETNA-LP, TESAV(H), TESND, JETDiR and JETDi.
    3. A group of units for special applications, which has been developed with a set of parameters exactly according to your requirements over the past 5 years – the newest TESD-SP and classic no‑optocoupler TESD with a very large output power range, from 10 W to 1000 W!
We’re looking forward to receiving your inquiries and letters about your needs in 2021! At the moment we updating our website and soon you will find published new series of products in its relevant product sections. Do not wait – contact us!

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.

New and improved power supply units have appeared in the list of our product range. To see the update product list, please go to our selection guide via following link:
https://www.aeps-group.com/wp-content/uploads/selection_guide_en.pdf.

JETA-LP lowprofile units series has a new member – JETA2000-LP, having increased power of 2 kW in the same dimensions as JETA1500-LP (250x140x36 mm).
At the moment both older JETA1500-LP and younger JETA2000-LP are 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.
