28VX2 200VA toroid transformer diy hifi power amp kit
2. Primary V = 140VAC, Primary I = .06A or core loss is 7Waat.
TEST CONDITION: Apply variable voltage to primary coil (115V terminals) from 1-20VAC at 60Hz and short circuit on secondary coils. The test result is 7.2V and 2.35A or 18Watt which is the maximum rated copper loss
1. Primary I = 0.02A, Secondary V = 28.1VAC at 0.0A, Power = 0 Watt
2. Primary I = 1.45A, Secondary V = 27.6VAC at 5.40A, Power = 149 Watt
3. Primary I = 2.12A, Secondary V = 27.1VAC at 8.2A, Power = 225 Watt
