    I am working with a variable load. The original set-up: a transformer is connected so it is part of the load side of the circuit. pri: 240V sec: 32V where the 240V line was connected to a SSR with a linear proportional controller then connected to the transformer. This is used to control the amperage on the secondary side of the transformer. It seems to me the 240V should run straight to the transformer and the secondary should be attached to the SSR, then to the load?

    Thanks for the input!

    It depends somewhat on the type of proportional controller that you are using; phase controlled triac or variable transformer. It can work both ways, with some limits when driving a chopped sine wave into a magnetic circuit being the less desirable of the two ways; (heating). A variable auto-transformer is probably the least noisy variable AC voltage source.
