Thank you for the reply OperaHouse. I forgot to add a vital piece of the pie. It needs to operate at temperatures as low as -40 F. So, if possible I would like to stay away from any additional batteries as this circuit has to be mounted outside of the heated cab of the vehicle.
I need to protect a 24 VDC system fed from a large mining haul truck for current/voltage spikes.
It's spec would range from 18-32 volts and .18 to .75 Amps.
Can anyone help me with this?
