Application Background
Global warming leads to an increase in thunderstorm weather
Severe hazards arise after power supplies are damaged by lightning strikes
High maintenance costs are incurred following lightning-induced power supply failures
Power supplies with high surge protection have become an industry trend
Solution Description and Precautions
The rear stage of this solution adopts TVS components featuring ultra-fast response time and low clamping voltage
The front stage uses surface-mount GDTs with large discharge capacity and compact size
An inductor L is employed in the middle for decoupling and driving the GDT to discharge large currents
This power supply solution complies with surge test standards such as IEC 61000-4-5 and GB/T 17626.5
This power supply solution can pass the 1.2/50μs-8/20μs combination wave surge test
Solution Applications
PTZ camera power supplies
Box camera power supplies
