In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead. 2. Inductance is for the primary, measured at 100 kHz, 0.1 Vrms. 3. Peak primary current drawn at minimum input voltage. Dot indicates pin 1 1 12 1 0.665 16,88 4. DCR for secondary is with windings connected in parallel. 5. Leakage inductance for the primary is with the secondary and drive windings shorted; leakage inductance for the drive winding is with the secondary windings shorted. 6. Turns ratio is with both secondary windings connected in parallel. 7. Output of the secondary is with the windings connected in parallel. 10 W output from 36 - 57 V PoE input or 24 V adapter; 6 W output from 12 V adapter. Bias winding output is 10 V, 20 mA. 8. Electrical specifications at 25C.
