800V ct 400V 400VA toroid tube amp transformer 70V tap
1. Primary V = 120VAC, Primary I = .04A or core loss is 5Watt.
2. Primary V = 140VAC, Primary I = .09A
TEST CONDITION: Apply variable voltage to primary coil (115V terminals) from 1-20VAC at 60Hz and short circuit on secondary coils and test the primary voltage and current. The result is 6.3V and 3.45A or 21Watt which is the maximum rated copper loss
TEST CONDITION: Input 115VAC 60Hz to the primary coil; parallel 2 secondary coils, 50 ohm 50W resistors as dummy load and room temperature at 25 degree C. Temperature rises 10 degree C after an hour test at load test #2.
1. Primary I = 0.04A, Secondary V = 405VAC at 0.0A, Power = 0 Watt
2. Primary I = 0.90A, Secondary V = 375VAC at 1.3A, Power = 475 Watt
Dimension 4.8 Diameter x 3.2 High.
