Regulatory markings on power supplies; what do they mean? When do I need them? Markings on power supplies, especially on external power supplies, contain important and very specific regulated information that is relevant for the geographical markets or application specific segments the product is designed to work in.
The ENERGY STAR program for External Power Supplies requires that manufacturers mark their power supplies using the international efficiency marking protocol. Any external power supply meeting the performance requirements for level V and above would qualify as ENERGY STAR (Version 2.0).
The international efficiency marking protocol provides a system for power supply manufacturers to designate the minimum efficiency performance of an external power supply, so that finished product manufacturers and government representatives can easily determine a unit's efficiency.
The new federal US standard for external power supplies (effective July 1, 2008) is identical to level IV above. This standard only requires compliance at 115 V/60 Hz. Pno is the Nameplate Output Power of the unit under test. In Australia and New Zealand, AC-AC external power supplies are not required to meet the no load power requirements.
