We proudly introduce our latest generation of specialized power supply solutions for tethered drone systems (TDS) – the JETNA-H-LP (AC/DC) and JETDH-LP (DC/DC) series. 

These two series allow construction of the power-pair. 

JETNA-H-LP is to be placed in the on-land part of the TDS. Fed from 3-phase mains and providing various levels of high voltage DC output  – 390-620 VDC. The DC voltage is transferred via cable over length of hundreds of meters to the tethered drone. There, on-board (aerial) power supply units JETDH-LP receive the high voltage and then provide low voltage output to the on-board electronics.  

Naturally, the series may be used separately. Both series may be controlled to provide flexibility of operation and accommodation to the immediate TDS needs. 

Thanks to continuous power supply, tethered drones can cover large areas without interruptions for recharging. The TDS may be equipped with various sensors and devices, as per needs of the customer, to gather data, monitor surroundings etc. This can bring benefits in both defence and industrial sector.

In the demanding world of military operations, where reliability and performance are paramount, we announce a new series of advanced power supplies, designed to the highest military standards. The modifications will affect such series as JETA-LP, JETNA-LP and JETDiR.

The first modified module – MIL-JETDiR DC/DC. This unit is in the final stages of testing, but we still have time to make changes. Therefore, we are ready to accept and consider your suggestions, what parameters you would like to see in this series of products. Write to us at aeps@aeps-group.cz and we will definitely consider and respond to all your suggestions that will affect the final product and make it as responsive as possible to the requirements of the modern market.

Below you can see the expected list of parameters of the new module

We are pleased to announce that our new JETDiV series of modules have been fully and successfully tested. These innovative devices are ready for operation and have demonstrated high reliability and functionality.

JETDiV modules can work simultaneously with DC and AC networks in the amount of up to 3-4 networks in total. This opens up new possibilities for their use in field conditions, where power from different sources is often required.

An additional benefit is reverse polarity protection, which makes the modules ideal for use in devices such as UAVs. This feature ensures the safety and durability of equipment, minimizing the risk of damage due to improper connection.

The new JETDiV series promises significant improvements in efficiency and ease of use, providing a reliable and versatile solution for work in the most difficult conditions.

We present the custom power supply module JETDiR-MIL-SUB-300.

For demanding applications that require reliability and resiliency, a new 300W power module is available, custom designed to meet military specifications MIL-DTL-24308, MIL-STD-461 CE101 and CE102.

This module has three independent electrical channels, which ensures uninterrupted operation even if one of the channels fails.

It also meets stringent electromagnetic compatibility (EMC) and vibration and shock requirements, making it ideal for use in harsh environments.

The power module has a compact and lightweight housing, making it easy to install in confined spaces.

It also features a highly efficient circuitry that provides low heat generation and high efficiency up to 89%.

For more information, you can contact us via email, phone or using the contact form on the website.

Currently, it is very relevant to solve power supply problems in active phased array radars, over-the-horizon radars, supercomputers and electronic warfare equipment. Due to the fact that on large structural areas of the equipment, power supply modules form a fairly clear structure with clearly defined rows and columns, that is, they have a matrix form, we decided to call such systems “Matrix power supply systems” (MPSS).
