PWM SSD3 setup on M150

Postby warrensupra on Fri Jun 12, 2020 9:09 am

Hello,

I am trying to set up a SSD3 with a Weldon 2345a fuel pump. The question I have is the wiring of the two input wires on channel 1. If you've wired this up and gets it to work, can you confirm how you wired up the two input wires? I find it confusing how they explain the low and the high current on the device itself vs. the printed documentation. Also, what frequency would be good to run it at. See attached.
Thanks

Each channel has 2 inputs (can't be PWM at the same time). A high and low input.

You should chose either a high or low for each channel and wire them together. That will drive both outputs together for your 2345a.
