Hi,
I'm having fun trying to learn electronic on myself but I need help here.
I've attached part of my schematic !
All I need is to connect a 12V DC .28A Fan on a 36V CT 72VA transformer without burning it or busting another fuse!
I have 53V DC on the circuit (due to C1 I assume) so I've divided the voltage in half between R5 (47 Ohms) and R6 (47 Ohms) to 26.5V and around 0.55A (V/Rt = 53 / 94).
I used a 7812 Positive Voltage Regulator (rated at 35V in and 1.5A) to insured the Fan receive 12V using 0,26A.
Any reasong why something should eexplode in the desing?? R5 seems to have a hard time surviving my experiment!
Thanks in advance!
