16VX2 300VA toroidal transformer diy hifi stepper motor
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 = 120VAC, Primary I = .03A or core loss is 3Watt.
2. Primary V = 140VAC, Primary I = .07A or core loss is 8Waat.
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 7.8V and 2.75A or 22Watt 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 #3.
1. Primary I = 0.02A, Secondary V = 16.6VAC at 0.0A, Power = 0 Watt
2. Primary I = 0.85A, Secondary V = 16.1VAC at 4.70A, Power = 75 Watt
3. Primary I = 2.92A, Secondary V = 15.4VAC at 13.5A, Power = 208 Watt
Dimension 4.8 Diameter x 2.9 High.
