Hi guys. Using the Motec M150 to PWM a Davies Graig 150 series electric water pump. The Motec will allow between 0 and 20,000 Hz. 0 is on only. So to PWM. 1 to 20,000 Hz. I’m running it at 1,000Hz now. Would you know/recommend the optimal Hz to PWM this pump. Thanks. Russell

I ran a couple of electric coolant pumps on an M1 using Half Bridge Outputs at 250hz without issue.
