Test products: power adapter;

Temperature and humidity of Leimao laboratory: 26 degrees, 61%;

Test standard: the surge test shall pass the IEC61000-4-5 standard ±1KV, and the test times shall be 10 times;

Test purpose: To test whether Leimao 05D471KJ and MB6S pass IEC61000-4-5 standard.

1. The requirements for testing products and standards are as follows:

Second, Lei Mao adopts circuit protection scheme (WeChat scanning applet QR code can see more protection schemes):

III. Records of photos and result data before the test is unchanged:

Fourth, the test was changed to Lei Mao 05D471KJ, MB6S photos and result data records:

It is recommended to select Leimao 05D471KJ and MB6S to meet the test requirements and have sufficient margin.

Summary:

The interface protection of electronic products needs over-voltage protection devices, and many engineers realize that protection devices are needed. However, due to improper selection or failure to follow the design principles of protection circuit PCB, the electrostatic test or EMC test of the products failed, and the products were repeatedly verified and tested, wasting manpower and financial resources, which always caused the products to be delayed in the market or over-designed, resulting in cost pressure. Leimao Electronics provides EMC design services for customers, provides laboratories to do bottom-up tests, and completes the design with high efficiency and convenient cost control, hoping to do our best for more customers to quickly pass EMC projects and improve product reliability. Leimao Electronic emc lab provides free testing and reference circuits for peripheral electrostatic protection. Leimao test equipment is available for customers to test for free.
