How to Make a 2-45V 20A Power Supply Using Toroidal Transformer || adjustable power supply 2-45V 

45v,40A= 1800W,with such a tiny transformer ? Is it a dream ?

Pls add short circuit on this project....

Is the mount a wood block or metal?

How if your toroidal has a 32v 0v 32v? So u make two of this assembly? Is this applicable to amplifier?

Hi....newbie here.what is the watts of 1k ohms resistor?and what is the value of led resistor?

how u so sure it is 20a? u did show 45v reading only. why u didnt test the current readin?
