Meet harmonics and flicker test standards IEC 61000-3-3 using the same power source. "Electromagnetic compatibility (EMC) - Part 3-2 Limits for harmonic current emissions (equipment input current ≤ 16 A per phase)"
Harmonics & Flicker Classification:
Equipment can be grouped into one of 4 classes based on the following criteria as evaluated by the IEC committee members:
- Number of pieces of equipment in use (how many (volume) are being used by consumers)
- Duration of use (number of hours in operation)
- Simultaneity of use (are the same type of equipment used on the same time frame)
- Power consumption
- Harmonics spectrum, including phase (how clean or distorted is the current drawn by the equipment)
After all the above criteria are taken into consideration equipment are classified as follows:
- Class A
- Balanced three-phase equipment
- Household appliances, excluding equipment identified by Class D
- Tools excluding portable tools
- Dimmers for incandescent lamps
- Audio equipment
- Everything else that is not classified as B, C or D
- Class B
- Portable tools
- Arc welding equipment which is not professional equipment
- Class C
- Class D
- Personal computers and personal computer monitors
- Television receivers
