In the case of ac loads, it is necessary to make a distinction
for power supply purposes between the individual
operating modes. In reverse phase control mode, figure 4,
Pin 15 must be 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
1
, is connected before the rectifier bridge and
therefore has only one mains half-wave. R
1
is then calcu-
lated as follows:

Power supply in reverse phase
control mode for ac loads
In two-wire systems, the additional power supply at
Pin 15 is not possible (see figure 4, by omitting R
1
and
Diode D
1
). In this case, the resistor R
sync
is identical with
R
1
and should be as low as the power dissipation allows
it. A sufficiently large residual phase angle must remain
in this case in order to guarantee the device supply.
The power supply is simplified if the device is operated
as a static zero-voltage switch for ac loads (see figure 5).
All delay times are twice as long here, since synchro-
nization of the module is tapped before the rectifier
bridge.
