Worked with the engineer on it and it doesn’t theoretically seem that there should be a problem. The switch outputs a full sine wave output as AC which is what the fan is expecting. He tested a similar load with a DC motor (with an AC input) and was able to switch the device on and off repeatedly without any issue. I would think they would need this device or another one with the problem to test in their lab. I’ll check to see if they can get a hold of one.
