Hi guys, I have just bought a 1500VA transformer, 240v primary to 2x 33v secoondary, giving a rectified output of around 46vdc.

Now I get confused. I have assumed 1500va / 33v to provide 45.45 amps output, so I have bought a 50 amp bridge rectifier. Will this be sufficient or do I need a larger rectifier?

If I need a larger recrifier, I have only managed to find 3-phase varieties with 5 pins. Can anyopne advise whether these can be used single phase, or recommend a suitable alternative please.

If it is of intereset, I am driving 3x DSG3 8020 drivers which draw a max current of 20 amps each but unlikely to ever draw more than 40 amps. Is there device which could limit the output from the power supply to 40 amps if this is an option?
