Finding a reliable alternative to power modules like Vicor can be a complex task. You need a solution that fits your existing board, but you also need to be certain that the internal logic aligns with your system requirements.

At Alexander Electric, we take a personal approach to providing drop-in solutions. We don’t just offer a substitute from a catalog. We offer our engineering expertise to ensure a seamless transition that respects your original engineering choices.

What does “Drop-In” mean to us? It means we focus on making the replacement process as smooth as possible for you:

• Physical Compatibility. We prioritize footprint and thermal alignment to minimize or eliminate the need for system redesigns.

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.

Contact us directly via aeps@aeps-group.cz or contact form here. If you have any questions, we’re here for you.

In critical situations and under challenging conditions, specialized devices, particularly tethered drones, may face external forces that could compromise their structural integrity and connections. In such circumstances, it is crucial for the device operator to swiftly resolve these issues on-site. Considering the potential for human error during the process of restoring the device’s functionality, even the simplest mistakes, such as mixing up the contacts, can occur.

As conscientious developers who prioritize the ongoing performance of our products, we have taken steps to support our end users. What does this mean? We have enhanced our JETDiV series modules by implementing polarity reversal protection. Whether you accidentally connect the positive and negative terminals in the wrong way (though we hope you avoid such errors), our module will operate correctly, ensuring reliability in extreme conditions and contributing to the success of critical missions.

This new feature has successfully completed all tests and trials, and we are now actively accepting orders!

We’re delighted to share some exciting news with you! Our DC/DC modules have successfully expanded their lower limit of the operating temperature range, now reaching an impressive -70 degrees Celsius. This significant enhancement applies to the JETDi, JETDiR, and JETDiV series.

But what does this mean for you? As you may be aware, our modules are utilized in devices and systems that operate in a variety of critical environments, including both manned and unmanned vehicles that carry out missions at altitudes of up to 40 kilometers. On average, for every 100 meters of altitude gain, the air temperature decreases by 0.6 degrees Celsius, or 6 degrees per kilometer, a phenomenon referred to as the vertical temperature gradient.

In essence, our modules are now capable of functioning at altitudes up to the Karman Line, which extends to approximately 100 kilometers. So, if you happen to have applications such as fighter jets, drones, weather probes, or any other devices conducting missions at altitudes nearing the edge of space, we strongly recommend using our power modules for the utmost reliability in your systems!

Some time ago we have announced our capabilities to produce high voltage input (and output) DC/DC converters in brick form-factors. While details about our JETDiR (300 W up to 1500 W) high-input-voltage units are still being decided – we have begun something similar.

Recently we have been receiving requests and questions whether we can provide pin-to-pin replacements (within same dimensions and same mounting footprint) for certain units. One of the requested replacements was for units of well-known converter producer – VICOR company. In particular their high voltage input Micro, Mini and Maxi families which offer Quarter, Half and Full brick formfactors.

We applied our JETDiR design principles and created pin-to-pin mount-to-mount units for input mains of 180-375 VDC and 250-425 VDC. Their preliminary datasheets can be found in custom VICOR replacement product section. We accept high-quantity short-lead-time orders for these and similar units!
