General

This Standard specifies a test method for calculating the energy performance of external power supplies (EPS) across a full range of load conditions. It covers single-voltage and multiple-voltage external ac-dc and ac-ac power supplies. Note: External power supplies are designed to convert line voltage ac into the low-voltage output (ac or dc) typically required by laptop computers, cordless and cellular phones, portable stereos, etc. EPS are contained in a separate housing from the product they are powering.

Purpose

The test method specified in this Standard is intended to complement the methodology contained in CSA C381.2. This Standard and CSA C381.2 define two classifications of products for the purpose of energy-efficiency testing; products within the scope of CSA C381.2 are not intended to be tested by this Standard. Annex B provides information on determining the appropriate test method (this Standard or CSA C381.2) for measuring a product's energy efficiency.
