Anti-interference wiring of DC circuit of electronic equipment
Source: InternetPublisher:消失的歌 Keywords: Anti-interference wiring electronic equipment Updated: 2021/10/28
Adding anti-interference capacitors to the input side of the DC power supply of electronic equipment
can suppress interference from the DC power supply. Its
wiring is shown in the figure.
In the figure, capacitors Cl and cz are used to resist high-frequency interference
, and C3 is used to resist low-frequency interference. Ri and R2 are
the voltage-reducing resistors of the voltage stabilizing circuit and can also play an anti-interference role
. CI - generally takes 0.22 ~ lyF/400V, C2 -
generally takes 0.1 ~ 0. 47_uF/50V, C3 - generally takes
100 ~ 500pF/50V; voltage regulator tubes vsl and VS2 are selected according to the working power supply voltage of the electronic equipment .
