1) Static air, SITAC soldered in pcb or base plate.
2) Test AC voltage in acc. with DIN 57883, June 1980.
3) The SITAC switch is soldered in pcb or base plate.
4) Termocouple measurement has to be performed potentially separated to A1 and A2.
The measuring junction should be as near as possible at the case.
5) The SITAC zero voltage switch can be triggered only in the hatched area below the
T
j
curves.
