By combining our design and manufacturing efforts we are able to reduce costs, gain productivity and share experience to inform our designs.

Electronic components such as transformers, potentiometers, speakers, and some capacitors are often stamped with a date code, which indicates the manufacturer and the manufacturing date.

N2= 117 , I1=10/220 , a2 = 1.139E-3 m², integ A1d V2 = 4.339E-7 but the result was M = 77.1 m H ( i multiplied the integ x 0.08 , the 3 dimension of core ) So the cooupling factor k = M / sqr(L1*L2) = 0.498You're using the wrong area for a2--this is probably ambiguous the way that I've written it up in the manual.You've used twice that area, so you calculated exactly half the coupling factor that you should be getting.Suenn Liang Electric is a professional electrical power transformer manufacturer in Taiwan.Jefferson Electric has manufactured dry-type transformer products since 1915.We provide quality products to the commercial, industrial and OEM marketplace.
