Siemens 3RT19 16-1JJ00 Surge Suppressor, Varistor Design, With LED, 10 - 120mW Power Consumption of LED, 24-48VAC Rated Control Supply Voltage

welcome back to my channel in this video we will discuss mov resistor vdr tvs what is there what is that if you see any power supply we see this component this blue shape component if we see this power supply this component is here if we check this board we have this red color v3 v2 v1 and if we see here in the same board it is written vdr3 the same component vdr3 it have some raised surface here in both sides and the same as vdr4 in red color vdr4 if we check this power supply for higher we have the same component it is vr1 and it is in z shape the symbol z shape in this power supply it is mentioned zd1 it is at input filter circuit in this power supply we have this yellow shape what is this component it is basically a question from one of my viewer from grace electronics so let's discuss it is resistor voltage dependent resistor or you can say it is mov metal oxide resistor vdr voltag
