Need a switch for open and close damper

I put a fresh air vent into my HVAC. I bought a mimolite thinking that it would provide 24vdc to the damper but I guess it is more of relay and I will have to get power from somewhere else to drive the damper? Could someone recommend another option

Well it is kind of hard to do that if the inout is only 13.5 V’s…Since that is the case does anyone have now of a 24VDC power supply I can use to directly connect to the damper and then I will just use a plug switch to control it.
