Test products: serial device server;

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

Objective: To test whether the serial port plus Leiyu SMD1206P010TF, SMD4532-090, SM712 and SMAJ36CA pass the electrostatic surge IEC61000-4-2 standard and IEC61000-4-5 standard. 

一．测试客户产品及要求指标如下：

Second, the protection scheme of the Leiditech circuit:

(1) 100M network port lightning protection scheme

(2) RS232 ESD protection scheme

(3) RS485 surge protection scheme

(4) DC24V power surge protection scheme

Third, test wireless image transmission transmission module photos and data records:

 Coupled with the PESD0542U005 device, it can pass the electrostatic IEC61000-4-2 standard and the group pulse IEC61000-4-4 standard.

Summary:

The interface protection of electronic products requires the use of overvoltage protection devices, many engineers realize that they need to use protection devices, but due to improper selection or not in accordance with ESD circuit PCB design principles, resulting in product electrostatic testing or EMC test failure, product multiple verification tests, waste of human and financial resources, resulting in product delay in the listing of things always occur, or overdesign, resulting in cost pressure.

Leiditech Electronics specializes in providing customers with electromagnetic compatibility EMC design services, providing laboratories to do thorough testing, from customers efficient, convenient to complete the design, hope for more customers can quickly pass EMC projects, improve product reliability as much as possible.

Leiditech Electronics Electromagnetic Compatibility Laboratory, free testing, provide peripheral electrostatic protection reference circuits. Leiditech test equipment for customers free test, welcome to contact Hu Gong 18016225001 at any time.
