Efficiency Calculator Encompasses Level VI, ErP Stage II & CoC Tier 2

Ideal Power has launched an improved efficiency calculator; which calculates target efficiency rates not only for the ERP Stage II Directive and DoE Level VI regulations, but also the CoC Tier 2 Scheme. Simply enter the required output voltage alongside the units' power or current and automatically receive target rates for all three.

The ongoing pursuit of improving electronic product performance and the impact on the environment has resulted in more stringent requirements being imposed on external power supply units through both the ErP Stage II Directive (EC 278/2009) and DoE (Department of Energy) Level VI Regulations.

The difference lies with the EU CoC (European Code of Conduct) Tier 2 which is a voluntary scheme established by an independent group of experts in a bid to standardize a higher efficiency level. Despite its purpose there are no plans to make the scheme mandatory to date.

The ErP Stage II directive, provides mandatory regulations on the efficiency of external PSU's (EPS) being imported into the European community. The directive sets limits to both the average efficiency level and no-load power consumption which must be met by an EPS for ac-ac, ac-dc or low-voltage PSU's.

The newest regulation; DoE Level VI (came into force on 10th February effect in 2016) setting more stringent levels to external PSU's (EPS) entering distributed in the USA. The new regulation covers a wider range of products by adding multiple-voltage units as well as high-power units (>250W).

In addition, the regulation prescribed exemptions for units that are intended for indirect operation (such as charging a battery), medical applications or supplied as spare parts, up until 2020.

Although the DOE Level VI is only compulsory within the USA, many manufacturers will ensure their products comply with the highest efficiency standards to enable global distribution, such as Ideal Power's 25HK-AY and 66JYH32 series.

As well as the improved efficiency calculator features, Ideal Power's new website also boasts a smart product selector, which will refine matching products by keyword, category, output voltage, current power and even input voltage - making the users' search for the right power solution as simple and straightforward as possible.

"The concept behind our new site has been to find solutions that overcome the challenges facing many professionals and customers alike within our industry." Ideal Power's Marketing & Sales Manager, Jon Vallis commented. "We hope to present an essential resource through the features and information made available."
