I am going to use the Racegrade SSD3 to PWM control my fans.

As I read the instructions I would use a Ignition/EFI B+ for the “Active High” input signal and then use an available LS output from the M150 to send a duty cycle signal to the “Active Low” input.

Has anyone configured one of these and can confirm?

Hi,

I would have the high side power for the Active High as a switched supply,that is only powered when the M1 is powered, otherwise your setup is correct.
