Neumüller Elektronik presents two new, non-insulated DC/DC converters from Delta Electronics in a small form factor of 1/32 brick. Both have an ultra-wide input range of 9 - 53Vdc and operate with a fixed switching frequency of 300KHz and achieve efficiencies of up to 98%! The level of the output voltage can be adjusted over a wide value range: With the T31SN12008 from 3.3V - 16.5V at max. 8A and with the T31SN24005 from 5V to 30V at max. 4.5A.
The power dwarfs come in 4 versions: Open Board THT or SMT or in a closed housing THT, cast with/without cooling flange connection. A possibility to regulate voltage drops over long output distances is provided by the remote sense input. Flexible assembly in manual/wave and reflow processes is possible. The function of the voltage transformers is safely possible up to a height of 5000m. Also approved according to: IEC/EN/UL/CSA 62368-1, 2nd Edition and IEC/EN/UL/CSA 60950-1,2nd Edition+A2. Delta's power dwarfs can be used to build very efficient and cost-effective distributed power systems.
