Variable Transformer:
More opotions to connect differernt induction coils:
Secondary connection at the front of the Transformer: Have 1 turn and 2 turns Secondary connection copper plate. Primary connection as the back of the transformer: Com is comm on Port: Connect the
Black one, this is must be connect it, Red port is options (8Turns,10Turns,12Turns, 14Turns,16Turns). Coil length connection From Long to Short sequence as follows: 8TURNS-10TURNS-12TURNS-14TURNS-16TURNS Means 8 turns can connect longest coil length, then will be 10turns--12turns-14turns --16turns.
So if you choose 2 turns primary connection, then transformer ratios as follows: 8:2(can as 4:1) Â 10:2(can as 5:1) Â 12:2(6:1) Â 14:2(7:1) Â 16:2(8:1) If you choose 1 turn primary connection, then transformer ratios as follows: 8:1 Â 10:1 Â 12:1 Â 14:1 Â 16:1 If use the same coil, Transformer ratios is smaller, Frequency will higher. Transformer ratios is bigger, the frequency will be lower. (Coil is smaller, connect the transformer ratio is bigger, coil is bigger, connect the transformer ratios is smalle
