>> The Application Background: 1 Thunderstorms frequently happened at nowadays 2 When the power supply is damaged, the damage is great. 3 Power supply lightning damage cause high maintenance costs 4 Power supply with high surge protection has become an industry trend >>program description and notes: 1 The back end of the circuit use the TVS with fast response and low clamping voltage as protecting solution 2 The front and use GDT with a large flow, small size and no continuous flow capacity as protecting solution 3 The inductor L2 and L1 is used for decoupling to drive GDT in action 4 This protection program meet the IEC61000-4-5, GBT17626.5 and other surge test standards 5 This power supply scheme can be combined with 1.2/50-8/20 S wave surge test >> Application: 1 Bullet Camara 2 Dome Camera3 Power adapter4 Led power5 Automotive power6 Other DC 12V power >> Protection circuit diagram
