注释

Output is for the secondary. Aux winding output is 12 V, 0.02 A.
Inductance is for the primary, measured at 125 kHz, 0.5 Vrms, 0 Adc.
Peak primary current drawn at minimum input voltage.
Leakage inductance is for the primary and is measured with the secondary shorted.
4500 Vrms isolation (hipot) from primary to secondary; 1500 Vrms isolation between primary and auxiliary.
