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°. This delay reduces the conduction angle, with respect to the AC Line by 7° from the values shown above.
