LED Tester | Christmas Light Tester - LISUN

Our engineer Jacky Jiang visit Spain to do installation & training for clients this month. And he also visited several local potential customers during this period. This customer is a luminaires manufacturer, they are very interested in our  LED test instruments . After learning that our engineer would do installation and training nearby, they arranged engineers to learn about the led test system in our client company and discuss with our engineer deeply here. After that, they warmly invited our engineer to visit their company. Here are photos in their company: [caption id="attachment_1293" align="aligncenter" width="800"] Figure 1: Group photo of the customer and LISUN engineer Jacky (second from the right)[/caption] [caption id="attachment_1292" align="aligncenter" width="800"] Figure 2: Group photo of the customer and LISUN engineer Jacky (the right)[/caption]

Surge generator  anti-interference measurement is based on the international standard IEC 61000-4-5. 1 Test objective The entire lightning stroke in the nature (namely the indirect thunder such as the lighting stroke between the clouds, or the lighting stroke happened to the adjacent objects) can induce the surge voltage and current in outdoor aerial. Besides, huge surge voltage and current will also be induced in the supply circuit of the instant switch in the power station or switching station. The common characteristics of the two kinds of surge include high energy (compared with the energy, the static electricity is P joule level, pulse group is the millijoule level, lightning surge is hundreds of the joule level, which is one million times of the former two interfering energy), slow waveform (microsecond level, but the static electricity and pulse group are nanosecond level, even the sub nanosecond level), and low recurrence frequency. IEC 61000-4-5 is a standard that prov...
