Semireglabil multitura 204 - 200k


Recommended Posts

Va salut. Am o intrebare pt. cunoscatori. Am o problema cu un semireglabi 204w. Nu stiu sensul  de rotatie pt. a creste rezistenta. Il folosesc intr-un circuit in care comand un NE555. Cati ohmi sunt pe o rotatie intreaga. Are un punct minim sau maxim la care se blocheaza sau il dau peste cap? Si al 2 lea potentiometru este un 203 - 100kohm comanda un IRFP 250. Le-am invartit in toate partile. Mi se arde siguranta de fiecare data. Va rog din suflet putin ajutor. Stima si respect. Mentionez ca sunt incepator.
