Hello, i am new here and i am in need of some help. I am trying to figure out how to limit DC voltage to a electric pump that has a maximum voltage rating of 12vdc @ 7.5A.
I am trying to install this pump in a custom project on my car, but the output voltage of my cars alternator is 14.4V@ 90A. i already have had one of these pumps installed running at 14.4 volts and after about 30 mins of running time it melted.
Electric pump specs:
Input: 6V-12V
Output: 15L/m
Current: 3.5A@6V Minimum
7.2A@12V Maximum
car electrical specs:
14.4V @ 90 amps
The manufacturer suggested that i run the pump at 9 VDC. I am looking for the easiest way to limit the voltage to the pump without building a complicated circuit or expensive circuit. I am trying to keep the cost very low as that is the nature off all DIY projects.
thanks
