B.1 United States

– ENERGY STAR for BC and ENERGY STAR Tier I (V1.1) and Tier II (V 2.0) for EPS

Revised U.S. ENERGY STAR levels became effective on November 1, 2008. Thesevoluntary levels are stricter than V1.1 levels, and provide separate levels for standard vs. lowvoltage models and for AC/AC versu s AC/DC models.

Power converters covered under this standard include all single-voltage EPSs with nameplate output power up to 250 watts, and battery chargers for heat, light, and motion products with a 42-V limit and a 2-watt to 300-watt input limit. Notable exclusions to V1.1 are de vices with detachable batteries, motor-operated devices, and medical devices. Notable

MEPS are administered by the Equipment Energy Efficiency Program, which is cofunded by the Australian and New Zealand Governments, as well as Australian state and territory
g overnments. MEPS are mandatory. Voluntary, higher efficiency levels exist, which will become the new MEPS in the future.

Power converters covered under this standard include all single-voltage EPSs with nameplate output power up to 250 watts. Notable exclusions are devices with batteries that attach

directly, replacements, and medical devices. No -load power requirements only apply to AC/DC power supplies.

The MEPS program does not yet deal with battery chargers but they are currently under

c onsideration. If specific MEPS are not introduced for battery chargers, the 1-watt standby
pr oposal will apply.

### B.7 EU (Subset of Member Countries) Group for Energy Efficient Appliances

Developed by the Group for Energy Efficient Appliances, which includes government agencies and institutions from Denmark, the Netherlands, Sweden, Switzerland, Germany, France, and Austria, the GEEA standards are voluntary. The purpose of the GEEA, organized in 1996, is to harmonize national regulations pertaining to electronics and home office equipment. Minimum energy-efficiency requirements are among the product characteristics GEEA addresses, including MEPS for external power supplies and battery chargers.

Power converters covered under this standard include all single-voltage EPSs with nameplate output power up to 150 watts. In addition to EPS and BC, this standard applies to portable personal equipment, which is defined as ―equipment that is sold as part of a product with non- removable rechargeable batteries and is sold with the aim of recharging batteries.‖

South Korea’s MEPS program for EP Ss, developed by the Ministry of Commerce, Industry, and Energy (MOCIE) and Korea Energy Management Corporation (KEMCO) is being implemented in three phases, with the ultimate goal of reducing standby power of all electronic products below 1W. Phase one of this program (2005-2007) was a voluntary limit on efficiency. C urrently in effect is phase two, which set mandatory standards for EPSs up to 150 watts (active mode and no-load power consumption) and lithium-ion BCs (no-load power consumption). Phase three will apply to those products not yet covered under the mandatory program.
