Ideal Power have launched a new tool that calculates the average efficiency that an external power supply must conform with to meet ErP II, stage 2.

This easy-to-use tool is extremely quick and at a glance, engineers, designers and purchasing professionals can work out what average efficiency value the power supply of their application or product is required to meet.

By simply inputting an output voltage and wattage, the calculator will use the official formula set by the 278/2009 ErP II compliance in the 2005/32/EC Directive, to provide the average efficiency rate required.

Contact Ideal Power if you would like some help with ErP II efficiency or you have any general questions regarding approvals and standards related to power supply and conversion products.
