1000 W Induction heater

[drummerdimitri]

So I was using my el cheapo induction heater with two 1500W power supplies in series for a total of 41 V DC as the unit works up to 48 V however I did not realize I was drawing 1500 W of power when the unit was only designed for 1000 W and now it just short out my power supplies but I have no idea how to troubleshoot it.

Here is the  link to the exact unit:

What component could I have fried? I'm guessing the power mosfets?

The output transistors / mosfets may have blown
