The hold-off condition also can be eliminated by pro-
viding a higher level of LED drive current. The higher
LED drive provides a larger photocurrent which
causes the phototransistor to turn-on before the com-
mutating spike has activated the zero cross network.
Figure 2 shows the relationship of the LED drive for
power factors of less than 1.0. The curve shows that
if a device requires 1.5 mA for a resistive load, then
1.8 times (2.7 mA) that amount would be required to
control an inductive load whose power factor is less
than 0.3.
