Table 3 in EN 61000-3-2 gives us two limits to satisfy with, one is maximum permissible harmonic current per watt (mA/w), the other maximum permissible harmonic current (A). The power limit for Class D equipment is 600W so that you always have to meet the maximum permissible harmonic current per watt limits. In other words, there is no such case that the EUT meet the per watt limits but not the maximum current limits. What's the purpose to have seperate limits for Class D equipment? Or do I miss something or have the wrong concepts? TIA
