JETDiR series power density increased!

14/03/2022

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 stand with Ukraine

03/03/2022

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.

TESND series power increased!

12/02/2022

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 F250 W (previously 40 W)
case F3 100 W (previously 60 W)
case F4150 W (previously 120 W)
case F5300 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!

New units TESND50-F2 and JETDiR40-R2B

19/01/2022

1. After successful experimentation and burn-in testing we have decided to increase the maximum output power of our TESND40-F2 unit to 50 Watts (and maximum output current to 10 Amps). The unit is now called TESND50-F2. Also, there is now a 3-isolated-channels version available in this form factor.
2. There is a new member of JETDiR series, 40-Watt unit in 1/16 BRICK format, called JETDiR40-R2B.

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!

New series of DC/DC converters with built-in MIL-STD-461F filters

18/04/2021


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”.

New member of JETDiR series – DC/DC converters for critical application

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.

New categories of custom power supply units and blocks

19/02/2021

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.

Selection guide of 2021

06/01/2021

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!
