34、dard BS6688: 1986, has been reworked and extended to take into account existing and forthcoming IEC standards.

35、LOW-VOLTAGE POWER SUPPLY DEVICES, DC OUTPUT PERFORMANCE CHARACTERISTICS 1 General 1.1 Scope and object This international Standard describes a method for specifying requirements for low-voltage power supply devices (including switching types) providing d.c. output(s) up to 200 V d.c. at a power leve
36、l of up to 30 kW, operating from a.c. or d.c. source voltages of up to 600 V. The devices are for use within class I equipment or for free-standing operation when used with adequate electrical and mechanical protection. This standard is intended to be used for all types of a.c. or d.c. driver power
37、supplies with any number of outputs, specially produced for an unknown final application. In the case where power supplies are developed as a component of equipment covered by specific product standards, these standards apply; the additional application of IEC 61204 may be useful as an option, espec
38、ially if the performance characteristics are not sufficiently covered by the product standard. It permits to specify a power unit to meet a particular application by the specification of parameters at required performance levels, to establish the essential definitions related to this type of equipme
39、nt, and to establish a selection of levels of performance. These levels are carefully graded to enable manufacturers and users to select and specify a range of power supply devices suitable for their application. 1.2 Normative references The following normative documents contain provisions which, th

All normative documents are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibi
