Figure AN1010.4 240 V ac Triac/Diac Circuit
Figure AN1010.5 illustrates a circuit using a sidac phase control
network to ignite a 240 V ac fluorescent lamp. This circuit works
basically the same as the 120 V circuit shown in Figure
AN1010.3, except that component values are changed to com-
pensate for higher voltage. The one major change is that two
K2400E devices in series are used to accomplish high firing volt-
age for a fluorescent lamp.
