TIMING CHARACTERISTICS
(See Figures 2 and 3):
All timings are based on fs = 60Hz, unless otherwise specified. 50Hz timings are 1.2 times 60Hz timings.

NOTE 1.
In the circuit schematic shown in Figure 5, the SYNC input signal is delayed in phase with respect to the AC Line by about 7擄. This
delay reduces the conduction angle, 脴, with respect to the AC Line by 7擄 from the values shown above.
