scope:

This standard applies to power supplies of assessed quality for electrical and electronic equipment. These power supplies carry out an AC-to-DC conversion or a DC-to-DC conversion with appropriate provisions for safety. As far as input characteristics are concerned, this standard applies to all DC or AC source voltages with a rated value up to 600 V. As far as output characteristics are concerned, this standard applies only to the supplies of DC voltages less than 200 V with a power limited to 2,5 kW; the latter power can be extended to 30 kW by taking care of the appropriate test methods.
