In Order to Complete the IEC61000 Electromagnetic Compatibility Test, How Many Waveforms Have You Set?

2021-12-24

Electromagnetic compatibility (EMC) testing is a test item that almost all electronic product manufacturers must comply with. The EMC standard is divided into two parts: electromagnetic emission and immunity test. The IEC61000-4 series standard is a basic standard promulgated by the International Electrotechnical Commission focusing on product immunity test. The electromagnetic compatibility of electrical and electronic equipment has different requirements. In the relevant test regulations, electronic product manufacturers need to find high-performance AC Power Supplies to fulfill the Power Supply requirements of special waveforms.
Take IEC61000-4-11 as an example. This is a standard test widely carried out at home and abroad. The domestic standard adopted is "GB/T 17626.11-2008 Electromagnetic Compatibility Test and Measurement Technology Voltage sag, short-term interruption and voltage change Immunity Test." Regulations require that the test should be carried out under the typical working conditions of the object to be tested for voltage sag, short-term interruption and voltage change. If it is a three-phase power supply system, test one phase and one phase. Do each item 3 times with an interval of 10 seconds.
It can be seen in the short-term interruption test that according to the different objects to be tested, different types of parameters need to be selected, including custom tests according to equipment requirements. If the user's product is sold globally and there are models that meet different power supply conditions, you need to edit multiple LISTs and call them one by one during the test. This increases the work of the engineer to edit and select the waveform, and it is difficult to intuitively understand the parameters of the running test during the test.
The built-in regulatory test function of the APM power supply not only provides standard test curves that meet regulatory requirements, but also provides custom functions. Users can edit and modify test items by themselves, and perform regulatory extended testing on the object under test. Of course, this type of power supply product also has host computer software, and these controls can also be completed through a computer.
SP-3U/6U series power supplies provide a power output of up to 36KW. It is suitable for the R&D, production and quality inspection stages in many fields such as new energy, rail transit, semiconductor and scientific research institutions.
