Low voltage power supplies, d.c. output - Requirements for low-voltage power supplies of assessed performance1 Scope and object This part of IEC 61204 applies to power supplies for general purpose applications. These power supplies carry out an a. c. to d. c. conversion or a d. c. to d. c. conversion. Appropriate provisions for safety will be found in the relevant product standards. As far as input characteristics are concerned, this standard applies to all d. c. or a. c. source voltages with a rated value of up to 600 V. As far as output characteristics are

based on the lifting cycle history rather than the traditional time period basis

BS 5258-9 also discusses the installation and servicing procedure for safe use of the product over time

BS 5502-21 provides users guidance on the selection of materials
