TESD, 10 W - 1200 W, no optocoupling, robust case with flanges

AEPS-GROUP power converters of TESD series have been created as a result of modernizing popular DC/DC converters TESD, MR, MDM while keeping original footprint and pinout, to ensure possibility of “pin-to-pin” replacement. The series is meant to support serial equipment production, which uses previous generation units with no-optocoupler feedback. Also, due to widening of available power outputs and increasing power density, modernized TESD series brings consumers more possibility to modernize their own equipment without their power system modifications.

TESD series consists of DC/DC converters TESD15, TESD25, TESD50, TESD100, TESD200, TESD300, TESD600 and TESD1200. 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 10, 20, 40, 80, 150, 200, 400 and 800 W respectively. The units are operated at 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).

Electrical features: all single channel TESND units utilize output synchronous rectification up to 27 VDC output, which significantly increases their efficiency up to 93 %. 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. TESD units include full set of service functions, up to providing active current sharing parallel operation.

Constructional features: series units TESD are made in compact dimensions and together with high efficiency the units achieve unprecedented power density of 31 to 70 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. Absence of optoelectronic components creates ability to work in environments with ionizing factors.

The units are optimal to be utilized in application fields 1, 2, 4, 5, 6, 8, 9 – 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 mining and radars.
