Hi Jay,A useful formula (from "Practical Transformer Design Handbook" by Lowdon) for a laminated silicon-steel core transformer:
P = (A*f/9.6)2 Where: P = power in watts A = core area in square inches f = operating frequency Bert -- ******************************************************************** We specialize in UNIQUE items: coins shrunk by ultra-strong magnetic fields, Captured Lightning Lichtenberg figure sculptures, and scarce technical Books.
