When you leave the country, you don’t just have to worry about different currencies and languages — you also have to worry about different plug shapes and electricity voltages. There’s no one standard socket shape or voltage. If you don’t do your homework ahead of time, you may be unable to use your electrical devices. Even worse, you may damage them by plugging them into the foreign outlets. The most obvious issue you’ll run into is that of the different electrical socket shapes used around the world. You’ll need the appropriate plug shape or you won’t even be able to plug your electronics into the power outlets in the country you’re visiting. The below diagram from Wikipedia gives us some idea of how plug shapes vary from country to country. Note that North America, continental Europe, the United Kingdom, and Australia all use different plug shapes. Luckily, plug adapters are easy to come by. You can buy fairly cheap adapters that will allow you to plug your electronics into the outlets in the country you’re visiting.

Important: You must also take voltages into account. ac power supply for car stereoIf you use an adapter to plug a device into the foreign outlet, it may become damaged if your electric device doesn’t support the voltage. how to change ac unit filterCheck the voltages first — see below for more information.ac unit for bedroom Plug shapes aren’t the only thing you need to worry about. Different countries also use different voltages and frequencies of electricity. If you plug in a device that isn’t rated for the outlet’s voltage, it may be seriously damaged. The below diagram from Wikipedia gives us some idea of the variation between countries. North American power outlets provide 120 volts at 60 Hz. Outlets in Europe provide 230 volts at 50 Hz. Voltages vary in other countries, too.

Read the small print on your devices to find out whether they support the voltages you need. For example, look at the print on your smartphone or laptop charging adapter. If you see something like the following, the adapter is rated to work both in North America and Europe: Chargers for laptops, smartphones, and tablets are often compatible with both voltage standards. However, you shouldn’t take this for granted — look at the fine print on every adapter before plugging it in. For example, Nintendo 3DS charging adapters are not compatible with both voltage standards. If your device is rated to work with the voltages in the country you’re visiting, all you need to do is use a plug adapter to connect it to the different physical plug. If you have devices that aren’t rated to work with the voltages in the country you’re visiting, you’ll need a “voltage converter” that plugs into the foreign outlet and converts the electricity to a different voltage. You can purchase multiple-outlet surge protectors with built-in voltage converters or use single-outlet converters.

Not all surge protectors are voltage converters — make sure you’re buying the right one. Consider both plug shape and voltage before traveling. For more information, look up the countries you’ll be visiting online and check the socket type and voltages they use. You’ll know the type of adapters and converters you’ll need to purchase ahead of time. Wikipedia has a good list of socket types and voltages used in different countries in its Mains electricity by country article. You may be able to pick up the adapters and convertors you need at an electronics store when you arrive, but don’t count on it — they can be hard to find. You should do the research and make your purchases ahead of time so you’re prepared. Image Credit: Plug standard diagram and voltage standard diagram from WikipediaThe requested Page was not found.

The global regulatory environment surrounding the legislation of external power supply efficiency and no-load power draw has rapidly evolved over the past decade since the California Energy Commission (CEC) implemented the first mandatory standard in 2004. With the publication in 2014 of a new set of requirements by the United States Department of Energy (DOE) that took effect in February 2016, the landscape has changed again as regulators further reduce the amount of energy that may be consumed by external power adapters.

In Europe, even more stringent requirements, which are currently voluntary, look set to become mandatory Ecodesign rules from January 2018. To help our customers stay on top of these continuously evolving global regulations, we have set out to push the energy efficiency initiative across our entire power portfolio. By continually monitoring the latest energy efficiency regulations, we ensure that not only our products, but our customers’ products are in compliance in each region where they are sold. Browse CUI's portfolio of DoE Level VI and CoC Tier 2 external ac-dc power supplies. The infograph below traces the path from the CEC’s 2004 regulation through to the DoE’s Level VI standards that went into effect in early 2016. It also shows the European Union’s Code of Conduct standards that are voluntary now, but are currently under review to become Ecodesign requirements in two tiers. The Tier 1 standard, which is broadly equivalent to Level VI, is proposed to become mandatory from January 2017 and the tighter Tier 2 standard is proposed to become mandatory from January 2018.

The above timeline demonstrates just how dynamic the regulatory environment has been over the past several years. As different countries and regions enact stricter requirements and move from voluntary to mandatory programs, it has become vital that OEMs continually track the most recent developments to ensure compliance and avoid costly delays or fines. While many countries are establishing voluntary programs harmonized to the international efficiency marking protocol system first established by Energy Star, the following countries and regions now have regulations in place mandating that all external power supplies shipped across their borders meet the specified efficiency level: The international efficiency marking protocol defines two performance criteria; no-load power consumption and energy efficiency. The table below summarizes the performance thresholds for each efficiency level as they were established over time: used if you do not meet any of the criteria no criteria was ever established

Regulated products now include: Multiple-voltage external power supplies Products with power levels > 250 watts The performance thresholds are summarized in the table below: Pout ≤ 1 W ≥ 0.5 x Pout + 0.16 1 W < Pout ≤ 49 W ≥ 0.071 x ln(Pout) - 0.0014 x Pout + 0.67 ≤ 0.100 49 W < Pout ≤ 250 W ≥ 0.880 ≤ 0.210 Pout > 250 W

The direct operation EPS standards do not apply if: EU CoC and Ecodesign Requirements The European Union published its Code of Conduct on Energy Efficiency of External Power Supplies Version 5 in October 2013. Tier 1 effectively harmonizes the EU with DoE Level VI, noting the differences in scope detailed below, and became effective as a voluntary requirement from January 2014, some two years ahead of Level VI.

Its adoption as an EU Ecodesign rule is expected to be mandated from January 2017. The more stringent Tier 2 became effective on a voluntary basis from January 2016 and is expected to become mandatory as an Ecodesign rule from January 2018. The key difference between the CoC requirements and Level VI is the new 10% load measure, which imposes efficiency requirements under a low-load condition where historically most types of power supplies have been notoriously inefficient. It is important to note that CoC does not distinguish between direct and indirect operation external power adapters. While CoC Tier 1 includes the new 10% load measure, its no-load and active mode limits are less stringent than DoE Level VI. CoC Tier 2 further tightens the no-load and active mode power consumption limits for key classes of power adapters enacted by Level VI i.e. at output powers ≤49 W and 49 W < Pout ≤ 250 W and covers both standard voltage and low voltage adapters. The table below details the additional requirements imposed by Tier 2. 0.3 W ≤ Pout < 1 W ≥ 0.50 x Pout +0.146 ≥ 0.50 x Pout +0.046 ≤ 0.150 1 W < Pout ≤ 49 W ≥ 0.0626 x ln(Pout) + 0.646 ≥ 0.0626 x ln(Pout) + 0.546 ≤ 0.150 49 W < Pout ≤ 250 W ≥ 0.890 ≥ 0.790 ≤ 0.250 Pout > 250 W
