IEC 61204-6 pdf download Low-voltage power supplies, d.c. output – Part 6: Requirements for low-voltage power supplies of assessed performance
This part of lEC 61204 applies to power supplies for general purpose applications.Thesepower supplies carry out an a.c. to d.c.conversion or a d.c. to d.c.conversion.Appropriateprovisions 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. sourcevoltages with a rated value of up to 6oo v.
As far as output characteristics are concerned, this standard applies only to the supplies of d.c.voltages of less than 200 V with a power limited to 2,5 kW; the latter power can be extended to30 kw by taking care of the appropriate test methods.
The object of this part of lEC 61204 is to set down the requirements for the performance oflow-voltage power supply devices of assessed functionality intended for serial production. lfother performance requirements or quality assurance have been agreed by a contract, thelatter prevails.
This part of lEC 61204 is intended as a guidance for the improvement of the performance oflarge series.
For performance and quality conformance inspection, the numbering of the clauses andsubclauses of this part of lEC 61204 refer, unless stated otherwise, to IEC 61204.

Procedure and classification
The requirements of this standard apply to
either the manufacturer’s standard power supplies meeting the requirements of the detailspecifications,
– or to specific, custom-made power supplies.The procedure includes the following three provisions:
the manufacturer’s quality control, methods and manufacturing procedures, shall becertified to the lso 9oo0 series or equivalent;
initial product compliance with the performance requirements;periodic quality conformance assessment.
