I need designs for two DC/DC converters cards to convert 800 volt 5 amp voltage source to 8000 volts for power transmission over 12-16 miles using small gauge wire. Control and status of both cards shall be via telnet protocol command line interface The up-converter shall be controllable via the down-converter telnet interface Up-convert on/off The up-converter shall report status via the down-converter telnet interface Up-convert status (On/off) Input voltage (volts) Input current (amps) Output voltage (volts) Output current (amps) Card temperature (degrees C with 1/10th of a degree resolution) Up-converter: - Input voltage: 800 volts DC - Input current: 5 amps - Output voltage: 8000 volts DC - Efficiency: 95% at full load - size: negotiable, but smallness is important - weight: negotiable, but lightness is important - temperature: must operate in environments -60 to -20 degrees C (enclosure heating is permissible, but heating must be able to be powered from ...
Fixed Price: $1,000 - $5,000

Im looking to create a new product. I need a cad drawing, 3D render, and would like a working model if anyone is that well versed and can handle all 3. I'll go into greater detail with the right candidate for this project. The item is about the size of a football. It's made of plastic parts and will feature some electronics as well. I'd like to get the ball rolling as soon as possible with the right group. Good luck... Feel free to ask questions. TH
