Technical knowledge：EMC Laboratory Introduction: Voltage Fluctuations and Flicker (Flicker) Section
I. Test Items
The test items clearly stipulate the limit requirements for voltage variations produced by the tested equipment under specified conditions, ensuring the stable operation of the power supply system. Applicable standards: EN/IEC 61000-3-3, EN/IEC 61000-3-11.
II. Test Objectives
Strictly limit the voltage fluctuations and flickering issues caused by electrical and electronic equipment in the public low-voltage power supply system, avoiding interference to the power grid and surrounding equipment.
III. Test Principle
By monitoring the voltage variation characteristics of the tested equipment after it is connected to the public low-voltage power supply system, precisely analyze parameters such as voltage fluctuations and flickering, and determine whether they meet the standard requirements.
IV. Equipment Capability
Core configuration: 30kVA three-phase power harmonic and flicker analyzer (Harmonic/Flicker/DIPs)
• Equipped with 30kVA AC/DC programmable power supply, supporting single-phase and three-phase AC flicker compliance testing
• Expandability: The system reserves upgrade space, and can be expanded to 45kVA in the future, meeting the product iteration requirements
V. Technical Advantages and Customer Value
1. Precise and Efficient
Equipped with professional waveguide darkroom and high-precision testing equipment, ensuring accurate and reliable test data, significantly shortening the product certification cycle.
2. One-stop Service
Provide pre-test → problem diagnosis → rectification and optimization → formal test report full-process technical support, efficiently solving EMC issues.
3. Global Recognition
Test reports comply with international mainstream regulations and standards, helping products quickly enter the global market and break through trade technical barriers.
