IEC 61204 pdf download Low-voltage power supply devices, d.c. output – Performance characteristics
1General
1.1Scope and object
This international Standard describes a method for specifying requirements for low-voltagepower supply devices (including switching types) providing d.c.output(s) up to 200 v d.c. at apower level of up to 30 kW, operating from a.c. or d.c. source voltages of up to 60o v.
The devices are for use within class l equipment or for free-standing operation when usedwith adequate electrical and mechanical protection.
This standard is intended to be used for all types of a.c. or d.c. driver power supplies with anynumber of outputs, specially produced for an unknown final application.
ln the case where power supplies are developed as a component of equipment covered byspecific product standards, these standards apply; the additional application of lEC 61204may be useful as an option, especially if the performance characteristics are not sufficientlycovered by the product standard.
lt 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 thistype of equipment,and to establish a selection of levels of performance.These levels arecarefully graded to enable manufacturers and users to select and specify a range of powersupply devices suitable for their application.
