TESND, 10 W - 1200 W, robust case with mounting flanges, critical application

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 TESND series in robust cases with mounting flanges are meant for universal input of DC mains 27W (15-50 VDC).

TESND series consists of TESND20, TESND40, TESND60, TESND120, TESND250, TESND500 and TESND1000. 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 153050100200, 400 and 800 W respectively.

Electrical features: all single channel TESND units utilize output synchronous rectification up to 24 VDC output, which significantly increases their efficiency. Galvanic isolation of outputs in two-channel variants, which broadens the functional application in creating equipment, with various connections of output channels: independent dual outputs, parallel-connected dual outputs, series-connected outputs to create high voltage output and common ground dual outputs. TESND250, TESND500 and TESND1000 units include full set of service functions, up to providing active current sharing parallel operation.

Constructional features: series units TESND are made in compact dimensions and together with high efficiency the units achieve unprecedented power density of 49 to 118 W/inch3. Case base has stiffening ribs and also serves for conductive cooling. Considering that all components significant in weight are connected to the base and submerged in hardened heat-transferring potting – resistance to and durability against mechanical stress is unique.

High efficiency of up to 93 % allows to provide extreme case operating temperature range up to -60…+130 °C.

AEPS-GROUP  series TESND 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 nits are also an optimal fit for telecom equipment, mining, supercomputers, radars and informational displays and screens, located in outdoors conditions. At the same time, TESND units operate in Arctic and Antarctica, in mountains at all heights and in cold or hot deserts etc.
