Hello colleagues, I want to put together some laboratory supplies with some traps that I have, I have a 220x45v 15am and another 220x33v 8am traffic, I want to build some good sources with these transfers, someone has some circuit to make good sources of multiple voltages ?? Thank you I await your comments.

SOLUTION ACCEPTED
Hi. have you searched the net? There are hundreds of diagrams of variable sources with greater or lesser complexity. Regards

    Hello, I was looking at some but almost all of them are to handle little amperage, I will continue to look for something that does not fail, since I want to build something and not have to change anything. Thank you

    Linear regulators for sources of large currents (more than 1 or 2 A) are extremely expensive since the power must dissipate in the form of heat. If it starts with voltages of 40 or 50 volts DC and it is intended to output 3V to 5A, the power dissipated by the regulator will be of the order of 200 to 250W!

    ricbevi, thanks for your answer, I think the most expensive thing I already have (transformers) for the rest It is not a problem, as far as heat dissipation is concerned I have many heat sinks of 2000w sound powers, I just need a good circuit recommended by a technician who already there Armed and tested with daily use.
