Hi all,
I have a DC input from a battery (36V) to a motor controller. However, sometimes a fully charged battery has up to 42V. Since my motor controller is rated for 40V I need some kind of a clipper circuit that cuts off any excess voltage.
The only thing I can think of is a Zener diode with zener voltage of say 36V. Will this work? how much resistance do I need to add in series to the power supply if the current could be as high as 3 Amps.
Are there better ways to accomplish this?
Thanks in advance!!
Cheers,
kaar
