aleph 1.7 power xformer

sakellogg · 23rd January 2011, 02:05 AM

anyone see a problem with using a 220-110 stepdown xformer for a aleph p 1.7 as power input. should be 60vac give or take.

i cant think of any but....could be wrong.

like this one

500 Watts Step Up/Step Down Voltage Transformer - eBay (item 180508056355 end time Feb-09-11 11:04:24 PST)

going to have to "diy" it to make it work.

thoughts?
thanks.

if you're going to use it with 220 primary at 110 mains voltage - then you're good - it will give ~55Vac at secondary ;

but - be sure that you have proper transformer , not just plain autoformer

considering smallish size of it , and 500VA claim , I bet - it's plain autoformer ....... so it don't have usual galvanically isolated primary and secondary

in that case - it isn't good for your needs

why dont you just get a 160VA 2x30V trans?
they are easy to get, and not too expensive.
