My plan is to put the wall dimmers before the transformers in the circuit.
something like this:
AC mains > wall dimmer > AC to DC transformers (wired in series) > power resistors > electromagnet
I am wiring two identical 24vdc 4A transformers in parallel to attain 24vdc @ 8A.
This is being used to power an electromagnet that maxes out at 24vdc @ 7.5A
I was told to add some power resistors to each transformer output to balance the currents drawn (0.1ohm/5W or less).
Is there a way...
variable controller electronic electromagnets
Thanks for the tips... I think the H-Bridge and PWM method might be a little advanced for me.
Could I just use some rectifiers in place of the transformers? They are much cheaper :)
what are the best ones to use? do you think i could just put a...
variable electromagnet
Hello,
I am building an array of 4 electromagnets & my goal is to have control over intensity & polarity for each one, independently.
I can power the magnets at either 18v dc (5.6A draw) or 24v dc (7.5A draw). I would prefer to work at 24V because that gives me a...
