US DoE publishes final EPS standard

The US Department of Energy (DoE) has published its latest efficiency standards for external power supplies (EPS) and has extended them to include several other EPS types; the new standards become effective in 2016.

In addition, the DoE has also confirmed that it may strengthen its current national Battery Charger Systems (BCS) standard to reflect the recently introduced CEC standard for consumer products with rechargeable batteries, such as mobile phones and media tablets [see CamSemi blog entry 26 Mar 13].

US EPA to end Energy Star BCS program

The US Environmental Protection Agency (EPA) has confirmed that its Energy Star Battery Charging Systems (BCS) program specification – for stand-alone battery chargers and systems sold with rechargeable products – will end on 3 June 2014.

The BCS efficiency programme is being stopped because it offers ‘limited additional cost savings’ when compared with existing, more stringent standards from the California Energy Commission (CEC).  The CEC standard for small non-USB BCS with battery capacity ≥ 20 Wh came into effect in February 2013; the standard for USB chargers is effective from February 2014.

EC approves EPS efficiency code of conduct V5

The European Commission has finalised and passed version 5 of its voluntary Code of Conduct (CoC) for external power supplies (EPS) [see CamSemi blog entry 19 Sept 12].

In previous versions of the CoC, the average active mode efficiency requirement used the average of efficiencies measured at 25%, 50%, 75% and 100% loads.  However, V5 has an additional minimum efficiency level at 10% load to specifically address applications that spend a significant part of their time in lower power standby or idle modes, such as networking product adapters.

Energy Star small network equipment specification V1.0 now in force

Energy Star has published its final V1.0 specification for small network equipment - such as modems, routers, switches and access points – and to take effect from 3 September 2013.  See CamSemi blog entry 21 May 13.

Energy Star publishes final lamps specification V1.0

Energy Star has published the final version of its lamps V1.0 specification that will replace the existing Compact Fluorescent Lamps (CFL) V4.3 and Integral LED Lamps V1.4 specifications in September 2014.

Most of the LED lamp requirements remain the same in the final draft including luminous efficacy, power factor (0.7 or greater for lamps >5 W) and colour rendering index (≥ 80).  However there have been some changes to dimming requirements with a clarification on measurements for noise and flicker.

Energy Star publishes new telephony specification V3.0 – draft two

Energy Star has published the second draft of its V3.0 telephony specification that covers cordless, corded telephones with EPS, wireless and conference phones.

Although the current specification only requires products to comply with standby power levels and EPS level V performance, the new draft proposes regulating power consumption based on product type, capability, added functionality and power management features.  The US Environmental Protection Agency plans to publish the final specification and test methods before the end of 2013 and with the programme effective from mid 2014.
