Open Circuit Test (core loss test): TEST CONDITION: Apply variable voltage to primary coil (115V terminals) from 115-180VAC at 60Hz. No load on secondary coils. 1. Primary V = 115VAC, Primary I = .02A or core loss is 2.3Watt. 2. Primary V = 140VAC, Primary I = .03A 3. Primary V = 160VAC, Primary I = .03A 4. Primary V = 180VAC, Primary I = .07A Short Circuit Test (copper loss test): 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 10.25V and 3.48A or 35.6Watt which is the maximum rated copper loss TEST CONDITION: Apply dielectric meter between primary coils and secondary coils; and increase voltage up to 3500VAC. No initiate any spark. TEST CONDITION: Input 115VAC 60Hz to the primary coil; parallel 2 secondary coils, 5 ohm 250W resistors as dummy load and room temperature at 25 degree C. Temperature rises 5 degree C after an hour test at load test #4. 1. Primary I = 0.02A, Secondary V = 18.4VAC at 0.0A, Power = 0 Watt 2. Primary I = 0.65A, Secondary V = 18.1VAC at 3.61A, Power = 65 Watt 3. Primary I = 1.20A, Secondary V = 17.7VAC at 7.08A, Power = 125 Watt 4. Primary I = 2.77A, Secondary V = 16.6VAC at 16.59A, Power = 275 Watt 5. Primary I = 4.00A, Secondary V = 16.4VAC at 24.11A, Power = 400 Watt Dimension – 4.6†Diameter x 3.22†High.
