here is the datasheet
i have 3 things that i want to know
1) what does æ symbol mean at quick reference data
2) are the 120v the maximum supply voltage? and if i get it right, the norman supply voltage is 50V dc
3) if i want to convert 220ac to dc, do i have to first transfer it to 72vac? if i am right, then after diode bridge and caps, it should be about 50v dc, am i right?
