This PS circuit seems rathed old fashioned. I opened a larged A/C unit from the same manufacturer, and which was installed at the same time. It's circuit board is only about half the size. Although this is a switch mode PS, it doesn't appear to use switch mode regulation. As far as I can see, there is no feedback from the secondary side back to the primary feedback circuit. Instead, there is a linear regulator in the secondary side to set the voltage for the electronics. For what it does, the PS primary circuit seems rather complicated. Sylvia.
