6.8 Thyristor control logic (switch)
Operating mode If the power controller is set to
r
Thyristor control
r
Logic (switch), the power
controller operates as an electronic switch.
For as long as the configured analog input is activated, the thyristors are fired
in zero crossing of the mains voltage and are only locked again when the ana-
log input is deactivated.
Transformer
loads In the case of transformer loads, the first mains voltage half-wave of each
pulse group must be cut. This can take place by configuring
α
start and enter-
ing a value.

Chapter 5.1.2 "Steller"
The phase control angle for each first half-wave can be selected between 0
and 90°.
Time behavior The TYA S201 is not suitable for the specific control of individual sine waves.
