- quickthrowman 11mo agoA 1.5kva isolation transformer is about $600, that fits with today’s pricing.
- crote 11mo agoIt's not about isolation though - it's about line noise. An isolation transformer will let that pass straight through (minus the usual filtering due to any transformer being an inductor), whereas the AC->DC->AC conversion gets rid of all of it by effectively acting as a perfect low-pass filter.
