12 volt dc automotive fan speed controller schematic needed using mj11032 or mj11016 darlington ( pref)
hi, i am after a basic type schematic to controll the speed of a 12 volt
dc automotive cabin fan . seems to be a bit of a problem in these saab`s. any schematic using a mj11032 or mj11016 darlington would be good. if not any electronic speed controll schematic will be fine. the original darlington is rated at about 25 amp , seems a bit excessive.... these darlingtons i have are rated at 30 and 50 amp. thanks, mark k |

But regardless it may not be optimal in any sense of the word. I assume you want to go PWM, right? (Drive the darlington with a 555?) |
