Yes, AC controlled SSR will work. Or use a wall wart plugged into your ranco output and connect the DC output of the wall wart to the input of a DC controlled SSR. Not very elegant but it will work.
I assume you're asking because you want use the ranco to control something outside of its output rating and you already have a ranco and don't want to buy another more suitable controller.
That solution crossed my mind but I wasn't sure if the wall wart could handle the switching.
You're absolutely right,
I want to control an electric heating element of 2200W, 220V. so it should take 10A and the Ranco is rated for just 8A.
