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 JETDi series in standard “Brick” formfactors are designed for universal input of DC mains 27W (15-50 VDC).
JETDi series consists of JETDi20, JETDi30, JETDi60 and JETDi120. The numbers state maximal output power in Watts, however to ensure long-term reliability the loading coefficient should be chosen from 0.7-0.8. Therefore, the series units are optimized for average power of 15, 20, 50 and 100 W respectively.
Constructional features: series units JETDi are made in compact dimensions and together with high efficiency the units achieve unprecedented power density of 49 to 83 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 hardened heat-transferring potting – resistance to and durability against mechanical stress is unique. However, it’s important to consider that mounting the units to a PCB is to be done mainly by its pins. Therefore, when using the units in certain cases it’s important to provide for additional bracing.
Electrical features: all single channel JETDi units utilize output synchronous rectification up to 27 VDC output, which significantly increases their efficiency. The units include full set of service functions.
JETDi units are able to operate without any heatsink. On request it’s possible to support with models of case operating range up to -60° to +130° C.
AEPS-GROUP JETDi units are optimal to be utilized in application fields 4, 5, 7, 8, 9, 11 – in environments without any significant mechanical factors (impacts and vibrations) – drones, hot air balloons and gliding devices, meteo-probes. 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, the units are able operate in Arctic and Antarctica, in mountains at all heights and in cold or hot deserts etc.
