... Monitoring the current flow after triggering. – Avoiding triggering due to an inductive load. The current synchronization as described above is a special feature of the U2010B. The device evaluates the voltage at the pulse output between gate and reference electrode of the triac result, no separate current synchronization input with specified series resistance is necessary. ...

... By using an LED between these pins (11 and 12), a high-load indication can be realized. If the potential at pin 6 increases to about 6 The result is programmable at pin 9 (operation mode). 3.8.1 Mode Selection U2010B 6 , there is a difference between both input currents at pins 1 and 2. This 6 , modulates this voltage. An increase of mains voltage causes the ...
