Outlet Power Scaling with Compact Fieldpoint

[Gizmaa]

Does anyone have any suggestions on scaling outlet power?  I have a fan which takes 115 VAC and .68 A but the PWM module can't handle that wattage.   I've considered using an electronic potentiometer but have yet to find one which suppports my requirements.  It's for a fan which we need to scale between 0 and full speed.

We have: 

Compact Fieldpoint 2120

cFP-AI-112 Aanalog input

cFP-PWM-520  Pulse width modulation output

cFP-TC-120  Thermocouple module

You may want to look for a small variable frequency drive.  Speed is varied by different frequency outputs.  You could control one by outputing an analog signal to it, or even using serial communication.
