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

AEPS-GROUP power converters of TESND series in robust cases with mounting flanges are designed for DC mains, typical for decentralized power supply systems with use of batteries: 12 (10.2-15 VDC), 12W (10.2-30 VDC), 24 (20-30 VDC), 24W (20-60 VDC), 27 (20-40 VDC), 27W (15-50 VDC) and 48 (36-75 VDC).

TESND series consists of TESND20, TESND40, TESND60, TESND120, TESND250, TESND600 and TESND1200. 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, 30, 50, 100, 200, 500 and 1000 W respectively.

Electrical features: all single channel TESND units utilize output synchronous rectification up to 27 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. TESND600 and TESND1200 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 54 to 142 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. There are also LP (low profile) variants with height reduction of 10-20 % available. Such planar design improves composability of units in the equipment.

AEPS-GROUP TESND 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 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.

High efficiency of up to 93 % allow maximum operating case temperature range up to -60…+130 °C on request.
