The series units, besides standard operation in a vast class of radioelectronic and electrical equipment, are meant to be used in critical missions: operation in emergency conditions, operation in case of compromised sealing of the equipment compartment, short-term higher than max power delivery, short-term full operation during surge or drop of input voltage.
AEPS-GROUP power converters of JETDiR series are provided in BRICK form factors, with counterbored mounting holes. Mainly meant for DC input mains of 28W (16-50 VDC) and 28 (16-40 VDC) for higher power models. Providing output power up to 600 W in standard case operating temperature range of -60 °С … +125 °С. Also available inputs – 48W, 48.
Unique feature of the series is their construction with counterbored mounting holes, making them the most compact among other types of products.
Electrical features: all single channel JETDiR units utilize output synchronous rectification, which significantly increases their efficiency. JETDiR300 – JETDiR1500 contain ability of active current sharing parallel operation.
Constructional features: series units JETDiR are made in compact dimensions and together with high efficiency the units achieve unprecedented power density of 49 to 113 W/inch3. Case base has stiffening ribs and also serves for conductive cooling. Considering that all components are constructively connected to the base and submerged in heat-transferring potting – resistance to and durability against mechanical stress is unique.
AEPS-GROUP JETDiR units are optimal to be utilized in application fields 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 – for aerial objects at heights up to 15 km in unsealed and unprotected spaces: planes, drones, helicopters, hot air balloons and gliding devices, meteoprobes. Also applied in all types of land transport – railway locomotives and wagons, cars, tracked vehicles. The units are also an optimal fit for telecom equipment, mining, supercomputers, radars and informational displays and screens, located in outdoors conditions. At the same time, JETDiR units operate in Arctic and Antarctica, in mountains at all heights and in cold or hot deserts etc.

Most commercial off-the-shelf (COTS) converters rely solely on fragile solder joints or weak plastic pins for mechanical stability. When subjected to continuous high-frequency vibration in aerospace or heavy military transport, these joints inevitably crack, causing catastrophic system failure. The JETDIR series eliminates this fatal flaw. Housed in a CNC milled case with counter-bore two-sided mounting holes, they can be rigidly bolted directly to the chassis or coldplate. This completely decouples mechanical stress from the PCB solder joints, ensuring ultimate survival in extreme shock environments.
Frankly, no. In tightly packed, unventilated compartments like radar domes, UAV fuselages, or engine bays, ambient temperatures easily exceed standard industrial limits. While standard converters derate heavily or melt, JETDIR power supplies are engineered to thrive in the heat. They guarantee reliable operation at an extreme case temperature of +125°C, while also starting effortlessly in deep freezes down to -60°C.
It’s all about advanced planar magnetics and uncompromising thermal management. The JETDIR600 achieves a staggering power density of up to 106 W/in³. Instead of using vulnerable cooling fans—which are the number one point of failure in power electronics—the entire internal volume is potted with a proprietary thermally conductive compound. Heat is uniformly transferred directly to the metal case, allowing for highly efficient baseplate conduction cooling through the mounting surface.
Heavy transport and defense vehicles have notoriously “dirty” power grids. Voltage spikes, load dumps, and starter motor drops easily exceed the narrow input ranges of typical telecom converters. JETDIR modules solve this by utilizing ultra-wide input ranges, such as the “28W” (16-50 VDC) standard. This allows the converter to absorb severe transients and battery voltage fluctuations in 24V/28V systems without dropping the load or taking damage.
If you designed your power architecture correctly using JETDIR, the system doesn’t even blink. High-power JETDIR modules (such as the 300W and 600W versions) feature built-in active current sharing for parallel operation. Engineers can easily build N+1 redundant arrays. If one unit goes offline, the surviving converters instantly and seamlessly absorb the load, ensuring absolute zero downtime for critical electronics.
