Harmonics on RDR194 Question on Class D limits
I was studying RDR-194 and found something I cannot explain:
According to the IEC, Lighting Equipment (Class C equipment) below 25W should meet the harmonics limits valid for Class D equipment.
This table tells me that for example the 3rd harmonic has a max permissable harmonic current of 3.4mA/W (table attached)
Your graph shows a limit value of about 95mA @ 115VAC (page 26 RDR-194; graph attached)
As this is a 14W PSU I cannot explain this high limit.
Can you explain?
