Hi all,
I need to create an adjustable power supply (AC) that ranges from 0-6 volts with roughly 1 ampere at 1 volt. I have a variac transformer (0-130 volts), an isolation transformer and a stepdown transformer. My question is, does it matter what order I step the voltage down? In other words, could I keep the variac in front of the stepdown transformer, and vary the input voltage of the stepdown transformer? Or should I step it down first then use the variac (even though the input voltage is rated at 120 v...)
Or does it not matter at all?
Thanks,
-Andrew
