Pentair iChlor 30 Salt Chlorine Generator Power Center

I have a Pentair iChlor 30 Salt Chlorine Generator. I dont not have a power unit for it. After looking online I found that I have to get a power center and it is over $300.00 (product is Pentair 520556 IntelliChlor Power Center). Is there a chaper alternative like a transformer for a different device that may also work?
