General Description
Mains Supply
2 U2010B
The U2010B contains voltage limiting and can be connected with the mains supply via
D₁ and R₁. Supply voltage – between pin 10 and pin 11 – is smoothed by C₁.
In the case of V₆ £ 70% of the overload threshold voltage, pins 11 and 12 are connected
internally whereby V_sat £ 1.2 V. When ½V₆½ ³ ½V_T70½, the supply current flows across
D₃.
