Did you read my previous post? The device normally runs hot. At 1A the resistance is about 2Ω which means its dissipating 2W. That's enough to make it very hot (hot enough to readily burn skin). If you read this data sheet you can better understand how it works.Checking with current it shows 1amp...i am measuring the current from the wire going to transformer inputs. Just wondering why it gets very hot...could it be normal? When cools down the resistance is ~47Ω....
