LED power adapter Current harmonics specification (IEC 61000-3-2)

EN 61000‒3‒2:2006+A1+A2 Elec­tro­mag­netic com­pat­i­bil­ity (EMC) — Part 3 – 2: Lim­its —

Lim­its for har­monic cur­rent emis­sions (equip­ment input cur­rent ≤16 A per phase)

Scope :

Inter­na­tional stan­dard EN 61000‒3‒2:2006+A1+A2 is applic­a­ble for elec­tri­cal equip­ment

that is sup­plied from mains net­work with volt­age not less than 220V and cur­rent up to 16A

(includ­ing) to limit the har­monic com­po­nent emis­sion.

From the scope of this stan­dard the fol­low­ing equip­ment are excluded:

Equip­ment with rated power less than 75W, except class C equipment.

Pro­fes­sional equip­ment with power >1kW.

Sym­met­ri­cally con­trolled heat­ing ele­ments with power ≤200W.

Inde­pen­dent dim­mers for incan­des­cent lumi­nar­ies with power ≤1kW.

Clas­si­fi­ca­tion :

Inter­na­tional stan­dard EN 61000‒3‒2:2006 +A1+A2 have clas­si­fi­ca­tion of equip­ment it cov­ers:

Class A:

• Three phase equip­ment

• House­hold appli­ances, except class D equip­ment

• Sta­tion­ary, fixed tools

• Dim­ming equip­ment intended to be com­bined with incan­des­cent lamps

• Audio equip­ment

• Other equip­ment that is not clas­si­fied as class B, class C or class D

Class B:

• portable tools

• non-​professional arc weld­ing equip­ment

Class C:

Class D:

Fol­low­ing type equip­ment with power less than 600W (includ­ing):

• Per­sonal com­put­ers and sim­i­lar

• Tele­vi­sion receivers

• light­ing equip­ment

Exam­ples :

Class A– fre­quency con­vert­ers, cook­ing appli­ances, fixed wood­work­ing equip­ment,

                  light­ing dim­mers, audio ampli­fiers, sub­woofers, heaters with reg­u­la­tion.

Class B– drills, elec­tri­cal ham­mers, portable min­ing equip­ment, non-​professional

                  arc weld­ing equip­ment.

Class C– LED light­ing, LED street light­ing and other light­ing equip­ment.

Class D– Per­sonal com­put­ers, tablets, lap­tops, TV.

Require­ments :

Con­ducted emis­sion require­ments cov­ered by this stan­dard are up to 40th har­monic.
