Hi,
I have three 25A outputs left on PDM and want to drive 3 fuel pumps(1 for sub tank,draw 10A maxmum and 2 identical pumps for engine,draw 15A each) and 1 air pump(16A max). Can I use one 25A output to drive the two identical fuel pumps with pwm control with 70% DC? Total current these two will draw should be around 21A. Is that ok to do so? And what frequency should I use if I want to use pwm control to control the fuel and air pump seperately?
Thanks.
Yuchen
