Solution

As the name suggests, surge is the instantaneous overvoltage exceeding the normal working voltage. Its sources are divided into external sources (overvoltage generated on the power line by lightning and switching operation in the power grid) and internal sources

Technical features

As the name suggests, surge is the instantaneous overvoltage exceeding the normal working voltage. Its sources are divided into external sources (overvoltage generated on the power line by lightning and switching operation in the power grid) and internal sources (air conditioning, elevator, electric welding machine, air compressor and other inductive loads). According to statistics, in the United States: shutdown, time loss, equipment maintenance Direct losses such as premature replacement of equipment are as high as US $26 billion a year. In China, according to relevant statistics, 63% of the electrical products with problems during the warranty period are caused by power surges. Our company is based on GB / T17626 5 iec61000-4-5 surge (impact) immunity test, and some sorting and testing of low-voltage DC lightning protection scheme are done for your reference.
