Re: Electronic Load
Hi
I custom designed one that can handle 2500W, 50V @ 50A about 2 years ago for a company to test aviation equipment on 48V. Will look if I can find the old drawings I had. This was variable from about 2-50V, 0.1A - 50
The important thing at these power levels is heatsinking. I used a massive, very high efficiency forced cooled sink with about 25 IRF1010 mounted on it. I also incorporated safety features like reverse voltage, over-current, over temp, over-volt protection. Because these power fets operate in a linear mode they get hot fast at full power.
