In the case of AC loads, it is necessary to distinguish the power supply purposes of the individ-
ual operating modes. In reverse phase control mode (see
additionally supplied with power via a dropping resistor, since no current flows in pin 16 when
the power switch is switched on. Here, the dropping resistor, R
has therefore only one mains half-wave. R

In two-wire systems, the additional power supply at pin 15 is not possible (see

should be as low as the power dissipation allows it. A sufficiently large residual phase angle
must remain in this case to guarantee the device’s supply.
The power supply is simplified if the device is operated as a static zero-voltage switch for AC
loads (see
