TESD, 10 W - 200 W, no optocouplers, metal housings with mounting flanges
The TESD series appeared as a result of the modernization of the popular DC / DC converters TESD, MR, MDM while maintaining their dimensions and pinout, to replace “pin to pin”. It is designed to maintain serial production of equipment using the previous generation of modules with optocoupler-free feedback. Also, by expanding the grid of capacities and increasing energy efficiency, the modernized TESD series gives consumers much more energy opportunities when upgrading their equipment without changing the power supply system.
This series consists of DC / DC modules TESD10, TESD15, TESD30, TESD60, TESD100, TESD200. The numbers indicate the maximum output power of the module in watts, however, to ensure long-term reliability, the load factor of these modules is selected in the range of 0.70-0.8. The modules are designed for electrical DC networks 28W (16 … 50) V, 12W (10.2 … 36) V, 24W (18 … 75) V.
Electrical advantages: All single-channel TESD modules contain synchronous rectifiers, which significantly increases their efficiency up to 93%. TESD series modules contain a standard set of service functions. Galvanic isolation of the output channels significantly expands the functionality.
Design advantages: TESD modules are small in size, which, combined with high efficiency, allows them to tolerate energy densities from 31 W / in3 to 65 W / in3. The module cases have stiffening ribs and at the same time serve for conductive heat dissipation – they are radiators. Considering that all components are structurally connected to the body and filled with a tough heat-conducting compound, the resistance and strength to mechanical stress is very good. The absence of optoelectronic devices allows working in conditions of ionizing influences.
On request, it is possible to perform for the operating temperature range of the case -60 ° C … + 125 ° C!
TESD series modules can be successfully used in flying and floating objects, in all types of ground transport. They are very optimal for telecommunications facilities, for supercomputers, for radars and information display screens located in external environmental conditions and, finally, in very wide temperature ranges of the environment – they work in the Arctic and Antarctica, in mountains at all altitudes and in cold and in hot deserts, etc., wherever a very wide input voltage range is required.
