TRIG PHASE ANGLE Ø SYNC TRIG (1) The TRIG Phase Angles shown in TABLE 1 are referenced to the SYNC input. In the Application Schematic shown in Figure 4A, SYNC is delayed by 7° from the AC line. Therefore, actual Phase Angles with respect to the AC line are 7° less than TABLE 1 values. TABLE 1 values are mask programmable. (2) The percentage of Full Power delivered to a resistive load by the Triac Switch.
