scope:

This recommended practice is written to provide a standard specification language for common parameters used to characterize the performance of electronic power distribution subsystem elements. Specifically, these are parameters relating to the integration of power supplies into electronic power distribution subsystems. The specification language consists of parameter definitions, test methods, and test conditions for the parameters. The specification language is meant to be used by both electronic power subsystem developers and designers and component manufacturers to insure unambiguous communication.

The specification language is intended to be applied to ac-dc and dc-dc electronic power distribution subsystems. The range of power subsystems includes single-phase and three-phase systems, with power levels from a fraction of a watt to 20 kW. The voltage range is from a few volts to 600 V, at a frequency or frequencies of dc -1 kHz. However, this recommended practice can be used outside the range.

Purpose

 The purpose of this recommended practice is to standardize a specification language, not to specify or enforce "a standard specification." A specification written in compliance with this language will ensure easy and precise understanding between manufacturers and users without, in any way, limiting manufacturers' ability to present features that are special to their products.

Efforts have been made to include as many common parameters as possible, but this recommended practice is by no means meant to be all-inclusive.
