9.5 Energy classifications

In accordance with the CELMA classification scheme, the following

classes to which the typical controllers belong are available:

• Class A1: Dimmable electronic control gear

•

Class A2: Electronic control gear with reduced losses

• Class A3: Electronic control gear (ECGs)

• Class B1: Magnetic control gear with very low losses

• Class B2: Magnetic control gear with low losses

• Class C: Magnetic control gear with moderate losses

• Class D:

Magnetic control gear with very high losses

Dimmable ECGs are classified as A1 if they meet the following re-

quirements:

• At a light power setting of 100 %, the ECG meets at least the re-

quirements according to A3 (OSRAM DIM ECG meet A2)

• At a light power setting of 25 %, the total power is the same or less

than 50 % of the power at the 100 % light power setting

• The ECG must be capable of reducing the light power to 10 % or

less of the maximum power
