Helo everyone. Forgive me for my english, I am French and I try to do my best.
I am a student, in april-may I will pass some competition for engineer school, one of the matter consist in the study of a technological objet of my choice.
I want to do it with an ups, but I have some difficulties in finding the good one. I am seeking for an ups using pwm technology, so I think that a line-interactive sinus may be good. Which ups do you recommend ? Considering I have about 100-200 $ ?
